Title: Production of alcohols, esters and the like from still gases of petroleum
IPC: C07C67/04
Filed: 1920-07-06
Abstract: Gases containing olefins, produced in cracking or distilling petroleum oils, are treated with sulphuric acid to produce alkyl hydrogen sulphates. The temperature, strength of sulphuric acid, and duration of contact of the gases with the acid, are regulated to avoid excessive tar formation, polymerization, etc.; temperatures below 30 DEG C., preferably from 10-20 DEG C., are suitable; the acid strength may vary between 1.54 and 1.84 specific gravity. The process may be carried out by passing the gases up an absorption tower filled with porous material down which the acid trickles. The resulting acid liquor is mixed with water to hydrolyze the sulphates, and the resulting alcohols separated by steam distillation or otherwise.  The alcohols (propyl, butyl, amyl, hexyl, &c.) may be esterified with acetic acid etc.; or the acid sulphate liquor may be esterified directly by treatment with acetic acid and distillation.
