COMPLEX LIQUID TARTIAL OXIDATION PRODUCTS AND ARTICLES PRODUCED THEREBY Ne Drawing. Application .filed July 13, 1920, Serial No. 520,715. Renewed December 7, 1923, a
In several of my copending applications such as Serial No. 272,567, filed January 22, 191$),f0r process of making aldehyde fatty acids, and Serial No. 281,124, filed March 7, 1919, now Patent No. 1,697,653, patented J an. i, 1929,- for intermediate partial oxidation product and method of making the same, I havedescrihed methods for the manufacture of intermediate oxidation products from mineral oils, including petroleum, shale oil, and a low temperature distillate of coal, by a method of partial combustion. The prodnets of such a. process lie in the range from. alcohols to aldehyde fatty acids and are mainly alcohols, aldehyde-alcohols, aldehydes, anhydrides, inner esters or lactone bodies, aldehyde fatty acids and similar compounds.
These products are present in different mo-- lecular weights, making the liquid mixture diificult to treat for obtainin difi'erent industrialproducts. I have discovered that fractioningsucha liquid into fractions of diderentboiling ranges aids in obtaining products; although not separating one body or class of bodies, from another body or class of bodies. I have also found that these aldehyde fatty acids and someof the aldehydelike bodies may be resinified and converted into resin-like bodies of commercial use either by themselvesor in compounds; The resinifying of these acids may be carried out in diflferent ways; but L prefer to prepare soaps from the aldehyde fatty acids and then liberate and resinify the aldehyde fatty acids,
for examplefby treating the soaps with cold dilute solutions of hydrochloric acid. The
resin acids formed have ahigher melting pointthan the untreated aldehyde acids and have different chemical and physical properties. Where hydrochloric acid is used dif- 'ferent strengths of solution maybe employed, and the mixture is preferably allowed to stand at a slightly elevated temperature of say to 60 degrees until the excess hydrochloric acid solution has evaporated. The acidtreatment will give especially hard resins. It is also possible to effect resinification by maintaining the free aldehyde acids for a considerable time at a somewhat elevated temperature such as 95 to 100 C.
I will now describe some specific examples of resinifying these acids:
Ewample 1 The aldehyde fatty acids were prepared by'my partial combustion process from Pennsylvania gas oil, the product containing other compounds such as alcohols and aldehydes, together with some unconverted hydrocarbons. Potash soaps were then formed from the aldehyde fatty acids, these soaps being separated from the reaction mixture. The potash soaps were then treated cold with a 4% solution of hydrochloric acid to slight excess. .Under these conditions resinification took place almost immediately. The resinified acids were washed with water and dried. The color of the resin acid mixture was light brown; it was brittle'at room temperature; softened at 72 (1.; had an incipient melting point at100 C., and was completely melted at 120 C. i
I, This mixture of resin acids dissolved readily in benzol. The solvent evaporated rapidly, leaving .adark brown varnish coating which was hard and tough and possessed fine gloss.
Likewise, the varnish-paint applicability of the material was shown by incorporating various pigments with the resin acids in the In the various tests under this example the ticular mineral acid used was shown. The
soap was prepared by potash saponification on the reaction mixture resulting from partial combustion of a Wyoming petroleum fraction of .83 specific gravity.
(a) The separated soap was treated with effect of different concentrations of the par- 4% hydrochloric acid solution cold with agi-f .tation., The resin acid product was dark brown, fairly brittle at room temperature and softened at 65 C. It was semi-liquid at 9 i G. and completel melted at 104C.
(b) A portion 0 the same product was treated by liberating the aldehyde fatty acid benzol solution. With the evaporation of with a solvent.
(0) Another portion of the same product was treated by liberating the aldehyde fatty acids in treating with a 40% solution of hydrochloric acid in the cold. The resin acids produced were dark brown and too soft to crush.
Example 3 The product mixture was made from partial combustion oxidation of a fraction from Wyoming petroleum having a specific gra'vity of .85. In this experiment, the product containing the aldehyde fatty acids was distilled before saponification, the residue above 200 C. being taken for resinifying. Soap was formed and the acids liberated from the soap by treatment in the cold with 10% hydrochloric acid solution and the organic acids allowed to stand for four hours at a tempera ture of 90 C. in contact with an excess of the mineral acid. Finally the acid solution was evaporated at a temperature of 60? 6., about 24 hours being required for this step. The resin acid product was dark brown, brittle at room temperature and softened at 'C. It w was semi-liquid at ,C. and completely liquid at 96 C. When-dissolved in benzol and applied as a varnish it gave a fine glossy coat on hard wood. When mixed with pigments, it gave good paint films on wood and iron.
In the above experiments, where the resin acid products were incorporated with pigments and applied as a paint (usually with benzol solution), the film while hard after a few minutes from evaporation from the solvent, increases in hardness for several days. This is probably due partly to saponification through the "formation of hard insoluble soaps by interaction of the metallic oxides and resin acids, and partly to an oxidizing action of the pigment or an oxidation by the oxygen of the air, the pigment acting as a catalyst. Other acids may be used for liberating the resinified acids, such as, other halo-. gen acids, sulphuricacid and the acids of phosphorus, with modifications of the process as to temperature and concentration.
The aldehyde acids may be resinified by heat alone, or by a combination of heat and acid treatment. In addition to the pigments above noted, which are the ordinary oxides and other compounds known in this art, I may incorporate with the aldehyde resin acids, calcium, zinc, lead, or other soaps of the aldehyde acids or of the resinified acids. These additions are particularly valuable in neeaeea all films where moisture excluding properties are desired. These paint or varnish mixtures the basis of which is the resin acid products dissolved in a solvent such as benzol,
are specially valuable for water-proofing concrete. I In this case, the free acids react with the bases present in the concrete to form water-proof acid compounds on and in the cement or concrete.
'- Linseed oil may be used as solvent with or ment-s, etc. Also the fractioning of the liquid partial oxidation product presents several advantages in producing industrial products from one or more of the separated fractions.
Some of the claims herein relate to fractioning, and other claims toan d including fractioning are contained in other of m pending applications. I
