Definitions
- This invention is directed to novel fuel compositions for internal combustion engines and to methods for using such fuel compositions.
- Additives for fuels such as anti-icing agents, lead-containing fuel additives, detergents, and various antioxidants generally resulted in adequate performance. Deposits in other parts of the fuel delivery system were not of a major concern because such engines were generally tuned to a rich air/fuel ratio allowing for mixture malfunction. Greater power-weight ratios meant that the driver was less apt to notice changes in peak power and fuel economy, and exhaust emissions were not a serious concern at that time.
- Another object is to provide novel fuel compositions that meet at least one of the above-stated objects and do not contribute towards valve-sticking.
- a further object is to provide a method for maintaining total intake system cleanliness in a gasoline-fueled internal combustion engine.
- Still another object is to provide a method for preventing or reducing the formation of intake valve deposits in a port fuel injected engine, or for removing such deposits where they have formed.

- alicyclic e.g., cycloalkyl, cycloalkenyl
- substituted hydrocarbon substituents that is, those substituents containing non-hydrocarbon groups which, in the context of this invention, do not alter the predominantly hydrocarbon substituent; those skilled in the art will be aware of such groups (e.g., halo (especially chloro and fluoro), hydroxy, alkoxy, mercapto, alkylmercapto, nitro, nitroso, sulfoxy, etc.);

- substituents a hydroxyl group, an A group as defined above, and an amino group, -NT 2 .
- Each of the foregoing groups must be attached to a carbon atom which is a part of an aromatic nucleus in the Ar moiety. They need not, however, each be attached to the same aromatic ring if more than one aromatic nucleus is present in the Ar moiety.
- the aminophenol of the instant invention contains at least one substituent of the formula -NT 2 .
- Each T is independently H or a hydrocarbyl group having up to about 28 carbon atoms.
- each T is independently H or an alkyl or alkenyl group.
- the alkyl or alkenyl groups contain from 1 to about 28 carbon atoms, more often from 1 to about 18 carbon atoms.
- at least one T is H with the other T being H or alkyl or alkenyl. In a most preferred embodiment, both T are H.
- the subscript c indicates the number of amino groups that may be present as substituents on the Ar group. There will be at least one such amino group substituent, and there may be more, depending on the values of the subscripts a and b. Preferably, c is a number ranging from 1 to about 5. In a preferred embodiment, c is one.

- the subscript b must be at least one; however, it may be a number greater than 1 as defined hereinabove.
- the maximum number of -OH groups that may appear on the aromatic moiety Ar depends upon the values for subscripts a and b. Preferably, there will be from 1 to about 5 -OH groups as substituents on Ar. In an especially preferred embodiment, there will be but one OH substituent on Ar, that is, the subscript b equals one.
- the aminophenols of this invention contain one each of the foregoing substituents -OH and -NT 2 (i.e., b and c are each 1), one A is an aliphatic hydrocarbon-based group with the remaining A groups being H, and but a single aromatic ring, most preferably benzene.
- An especially preferred class of aminophenols can be represented by the formula
- R' group is a substantially saturated hydrocarbyl group of about 30 to about 400 aliphatic carbon atoms located ortho or para to the hydroxyl group
- R" is a lower alkyl, carboxy lower alkyl, lower alkoxyl, nitro group or halo group
- p is 0 or 1.
- p is O
- R' is a substantially saturated, purely hydrocarbon aliphatic group. Often it is an alkyl or alkenyl group para to the -OH substituent. Often there is but one amino group, -NH 2 in these preferred aminophenols but there can be two.
- the aminophenol is of the general formula
- R' is derived from homopolymerized or interpolymerized C 2-10 1-olefins and has an average of from about 30 to about 400 aliphatic carbon atoms and R" and p are as defined above.
- R' is derived from polymerized ethylene, propylene, butylenes and mixtures thereof. Typically, it is derived from polymerized butenes. Often R' has at least about 50 aliphatic carbon atoms and p is 0.
- the aminophenols of the present invention can be prepared by a number of synthetic routes. These routes can vary in the type reactions used and the sequence in which they are employed. For example, an aromatic hydrocarbon, such as benzene, can be alkylated with an alkylating agent such as a polymeric olefin to form an alkylated aromatic intermediate. This intermediate can then be nitrated, for example, to form polynitro intermediate. The polynitro intermediate can in turn be reduced to a diamine, which can then be diazotized and reacted with water to convert one of the amino groups into a hydroxyl group and provide the desired aminophenol. Alternatively, one of the nitro groups in the polynitro intermediate can be converted to a hydroxyl group through fusion with caustic to provide a hydroxy-nitro alkylated aromatic which can then be reduced to provide the desired aminophenol.
- an aromatic hydrocarbon such as benzene
- an alkylating agent such as a polymeric olefin
- This intermediate can then be nitrated,
- Another useful route to the aminophenols of this invention involves the alkylation of a phenol with an olefinic alkylating agent to form an alkylated phenol.
- This alkylated phenol can then be nitrated to form an intermediate nitro phenol which can be converted to the desired aminophenols by reducing at least some of the nitro groups to amino groups.
- Aromatic hydroxy compounds can be nitrated with nitric acid, mixtures of nitric acid with acids such as sulfuric acid or boron trifluoride, nitrogen tetraoxide, nitronium tetrafluoroborates and acyl nitrates.
- nitric acid of a concentration of, for example, about 30-90% is a convenient nitrating reagent.
- Substantially inert liquid diluents and solvents such as acetic or butyric acid can aid in carrying out the reaction by improving reagent contact.
- reaction can be carried out at temperatures of about -15oC to about 150oC, usually between about 25-75"C, for a period of time sufficient to attain the desired degree of nitration.
- nitrating agent about 0.5-4 moles of nitrating agent is used for every mole of aromatic nucleus present in the hydroxy aromatic intermediate to be nitrated. If more than one aromatic nucleus is present in the Ar moiety, the amount of nitrating agent may be increased proportionately according to the number of such nuclei present. Up to about a 5-molar excess of nitrating agent (per "single ring" aromatic nucleus) may be used when it is desired to drive the reaction forward or carry it out rapidly.
- Reduction of aromatic nitro compounds to the corresponding amines is also well known. See, for example, the article entitled “Amines by Reduction” in Kirk-Othmer “Encyclopedia of Chemical Technology", Third Edition, Vol. 3, pages 335-376.
- reductions can be carried out with, for example, hydrogen, carbon monoxide or hydrazine, (or mixtures of same) in the presence of metallic catalysts, when needed or useful, such as palladium, platinum and its oxides, nickel, copper chromite, etc.
- Co-catalysts such as alkali or alkaline earth metal hydroxides or amines (including aminophenols) can be used in these catalyzed reductions.
- Reduction can also be accomplished through the use of reducing metals in the presence of acids, such as hydrochloric acid.
- Typical reducing metals are zinc, iron and tin or salts thereof.
- Nitro groups can also be reduced in the Zinin reaction, which is discussed in "Organic Reactions", Vol. 20, John Wiley & Sons, N.Y., 1973, page 455 et seq.
- the Zinin reaction involves reduction of a nitro group with divalent negative sulfur compounds, such as alkali metal sulfides, polysulfides and hydrosulfides.
- nitro groups can be reduced by electrolytic action; see, for example, the "Amines by Reduction” article, referred to above.
- One preferred method for obtaining the aminophenols of this invention is the reduction of nitro phenols with hydrogen in the presence of a metallic catalyst such as discussed above. This reduction is generally carried out at temperatures of about 15oC-250oC, and hydrogen pressures of about 0-2000 psig. The reaction time for reduction usually varies between about 0.5-50 hours.
- the aminophenol product is obtained by well-known techniques such as distillation, filtration, extraction, and so forth.
- Another preferred method for obtaining the aminophenols of this invention is the reduction of nitro phenols with at least one hydrazine source, optionally in the presence of at least one metal-containing hydrazine decomposition catalyst.
- the hydrazine source used in the present invention is hydrazine, a hydrazine compound or mixture of compounds which are capable of producing hydrazine in sufficient quantities to react with the nitro phenol.
- Hydrazine, hydrazine compounds and many hydrazine sources are known to those of skill in the art. See, for example, the book entitled “Hydrazine” by Charles C. Clark, published by the Mathieson Chemical Corporation of Baltimore, Maryland (1953), particularly pages 31 through 71 and 120 through 124; and the book entitled "The Chemistry of Hydrazine” by L. F. Audrieth and B. A. Ogg, published by John Wiley and Son, New York (1951), especially pages 209 through 223.
- hydrazine and particularly its solutions with water and other solvent/diluents is preferred.
- the reaction of the nitro phenol with the hydrazine source takes place in the absence of metal-containing hydrazine decomposition catalyst.
- Metals may be present in pure, alloyed or chemical combined form as parts of metallic equipment such as stirrers, pipes, vessels, probes, etc., and in such form they may be in contact with the reaction mass without significantly affecting the course or rate of the decomposition or reaction of the hydrazine source present in the mass. In such cases, for the purpose of the present description, the reaction is said to take place in the absence of a metal-containing hydrazine decomposition catalyst.

- each A is independently H or a hydrocarbyl group
- a, b and c are each independently an integer of at least 1 with the proviso that the sum of a, b and c does not exceed the unsatisfied valences of Ar
- Ar is an aromatic moiety having 0 to 3 optional substituents selected from the group consisting of lower alkyl, lower alkoxyl, carboxy lower alkyl, halo, or combinations of two or more of said optional substituents; with the proviso that when Ar is a benzene nucleus having only one hydroxyl and only one A which is hydrocarbyl, the hydrocarbyl A group is ortho or para to said hydroxyl substituent.
- An alkylated phenol is prepared by reacting phenol with polybutene having a number average molecular weight of about 1,000 (vapor phase osmometry) in the presence of a boron trifluoride/phenol catalyst. The catalyst is neutralized and removed by filtration. Stripping of the product filtrate first to 230°/760 torr (vapor temperature), then to 205°/50 torr (vapor temperature), provides purified alkylated phenol as a residue.
- Kieselguhr catalyst is charged to an autoclave under a nitrogen atmosphere. After purging and evacuation with nitrogen three times, the autoclave is pressured to 100 psig. with hydrogen and stirring is begun. The reaction mixture is held at 96° for a total of 14.5 hours while a total of 1.66 moles of hydrogen is fed to it. After purging with nitrogen three times, the reaction mixture is filtered and the filtrate stripped to 120°/18 torr. Filtration provides the desired aminophenol product as an oil solution.
- a mineral oil solution (1900 parts) of an alkylated, nitrated phenol as described in Example 1 containing 43% mineral oil is heated under a nitrogen atmosphere to 145°. Then, 70 parts of hydrazine hydrate is slowly added to the mixture over 5 hours while its temperature is held at about 145°. The mixture is then heated to 160° for one hour while 56 parts of aqueous distillate is collected. An additional 7 parts of hydrazine hydrate is added and the mixture is held at 140° for an additional hour. Filtration at 130° prov is an oil solution of the desired product containing 0.5% nitrogen.
