IARBENINDUSTRIE AKTIENGESELLSCHAIT, F FRANKFORT-ON-THE-MAIN', GEE- MANY, A. CORPORATION OF GERMANY 7 PRODUCTION OF VALUABLE ORGANIC OXYGEN GOMPOUl-TDS Ho Drawing. Application filed September 12, 1928, Serial No. 305,816, and in Germany November 5, 182?.
This invention relates to the'pr'oduction of valuable organic compounds.
I have found that valuable oxygen compounds can be produced from non-aromatic hydrocarbons e. g. from aliphatic or hydro-- aromatic hydrocarbons, or mixtures thereof by the action thereon of carbon monoxid under pressure, in the presence of anhydrous halides of aluminium or boron or-mixtures 10 thereof, the pressure being variable within wide limits. A suitable working pressure is from about 80 to 150 atmospheres, though it will be understood that lower and any attainable higher-pressures may be employed. The reaction proceeds, though slowly even in the cold and at rather low pressure such as about 50 atmospheres but it is preferable to work at an elevated temperature and at a pressure above the aforesaid pressure though, when heating, a pressure of about 10 atmospheres only can be applied.
Both individual hydrocarbons, and the cheaper mixtures of hydrocarbons, such as occur in the various petroleum fractions and are practically free from aromatic hydrocarbons, as for example petroleum ether, ligroin, lamp oil and purified petroleum elly, also brown coal tar oils, the products of a destructive hydrogenation of substances of the nature of coal, tar, mineral oils and the like, cracking products and similar substances may be treated in this manner.
In the abovereaotion besides aluminium chlorid, anhydrous aluminium bromid, b0- ron fluorid and the like may be employed.-
The following examples will further illustrate the nature of the said invention which however is not limited thereto. The parts are by weight; 4

repeated admission of carbon monoxid under pressure, whereupon carbon monoxid is admitted under a pressure of from about 126 to 150 atmospheres, and the retort is heated to a temperature of about between 35 and 60? 0., the stirrers being set in motion. A sorption of carbon monoxid begins after a short time and the pressure drops to from to atmospheres in the course of 5 8 hours. More carbon monoxid is then forced in until a. pressure of to atmospheres is again attained, stirring being continued, and the admission of carbon monoxid is repeated until no further drop in pressure oc- The reaction product consists of two liquid layers. The upper is composed or unaltered pentane and is removed. The dense, viscous lower layer is a double compoundof aluminium chlorid and the reaction product. It is poured onto ice, acidified with hydrochloric acid and distilled in a current of steam. The major portion passes over with the steam and is contained in the distillate as an oily layer. After separating the oil from the water, shaking it with dilute caustlc soda-solution and separating again, 1t 1s fractionated by distillation. A considerable portion thereof boils between 114- and 116 C. and is obtained as a colorless liquid having a strong odour. The analysis of the product gives values corresponding to the formula O H O; the product is identical with ethyl isopropyl ketone. The main fraction boils between 116 and 250 C. and consists of a mixture of higher ketones which have probably been produced by condensation of the above mentioned simple ketone under the influence of the aluminium chlorid. The said higher ketones consist of colourless oils having a pleasant odour similar to that of menthol. From the caustic soda solution an oil with a rancid odour'can be recovered by acidification, which oil boils between and 300 C. and consists-for the tort is heated u main portion of a carboxylic acid corre- Ezample 2 A high (pressure retort fitted with stirrers is charge with 100 parts of cyclo-hexane and parts of anhydrous aluminium chlorid. Air is'expelled from the vessel by repeated admission of carbon. monoxid under pressure, followed by release of the ressure, whereupon carbon monoxid is a mitted undera pressure of about 120 atmospheres and the reto about C. The reaction soon be 1118, the tem erature rising somewhat, an the pressure ro s rapidly to about20 atmospheres. More car on monoxid is then forced in until a pressure of 120 atmospheres is attained and the admission'of carbon monoxid isrepeated until no further dro in pressure occurs.

In place of c clohexane, other hydroaromatic hydrocar ons such as hexahydro toluene, or mixtures of hydroaromatic hydrocarbons from mineral oils, orthe products of the destructive hydrogenation of substances of the nature of coal, tar, mineral oils and the like, lignite tar oils and similar substances may be employed.

About 300 parts of a colorless oil of agreeable smell is obtained which possesses a similar composition as the product obtained form n-pentane according to Example 1. I

By working u there is obtained about 400 parts of a (la oil of peculiar smell which can be fractionated by distillation, the fractions of lower boiling point possessing a pleasant'aromatic odour.
