Die Umwandlung der gesättigten Kohlenwasserstoffe in die ungesättigten kann z. B. durch destruktive Destillation vorgenommen werden.

Die Jodzahlen der Destillate liegen zwischen 60 und 70. Man oxydiert die Destillate mit Chromsäuregemisch, verseift die Oxydationsprodukte und treibt die unveränderten Kohlenwasserstoffe ab.

unsaturated hydrocarbons are also formed. The formation of these unsaturated hydrocarbons is seen as a harmful side reaction: one tries to counteract it or to saturate the unsaturated compounds once formed by hydrogenation.
In contrast to this, the new process aims to convert the saturated hydrocarbons of the aliphatic and hydroaromatic series into the valuable intermediate
EMI1.2
The conversion of the saturated hydrocarbons into the unsaturated can, for. B. be made by destructive distillation. In the case of hydrocarbons of high molecular weight, it is sufficient: slow distillation anyway. The synthetic hydrocarbon Pentatriakontan gave z. B. with very rapid heating to 350 oi @ 400 a distillate that is only 38.5 #. in another case 39% liquid hydrocarbons. Iodine number = 66, while lei distilled very slowly (thermometer in the steam

Example 1: Over 200 to 250 boiling petroleum fractions are evaporated by dropping them into a hot quartz container and the vapors are condensed in a cooler system. The iodine numbers of the distillates are between 60 and 70. The distillates are oxidized with a chromic acid mixture, the oxidation products are saponified and the unchanged hydrocarbons are driven off. The acids then separated from the soaps have acid numbers of 250-275.
EMI1.5
level of fumes expelled. At about 4000 a mass still containing solid parts passes over, which when rectified gives a completely liquid distillate, iodine number 74.
The distillate is treated in the usual manner with the amount of permanganate calculated from the iodine number. the oxidation product is saponified and broken down into fatty acids and unchanged hydrocarbons. The insoluble fatty acids have acid numbers of around 220 to 250 and have a pleasant, characteristic odor that is reminiscent of that of palm kernel oil acids.
