Abstract

Addition products of olefines such as alcohols, ethers and esters are produced from olefines and water or steam in the presence of vapours of organic acids such as acetic or trichloracetic acid. The temperature may be 150-550 DEG C. and the pressure 5-100 atmospheres. The reaction may be effected in presence of catalysts which promote hydration reactions such as oxyacids of phosphorus or salts thereof or zinc chloride, and/or contact or filling materials such as pumice and kieselguhr. For the production of alcohols less than two volumes of olefine to one of steam, and for ethers a considerable excess of olefine such as two to three volumes of olefine to one of steam may be used. Some of the alcohol may combine with the organic acid to form an ester, which may subsequently be hydrolysed. The olefine may be caused to combine directly with the acid by using little or no steam. The products may be separated by fractional condensation with or without the use of an entraining liquid. The production of isopropyl alcohol from propylene and steam is mentioned. Mixtures of olefines such as mixtures of ethylene with propylene or butylene may be used as starting materials. In an example, a mixture of 3 volumes ethylene, 2 volumes steam and 1 volume of acetic acid vapour is passed repeatedly through a tube containing pumice at 450 DEG C. and 20 atmospheres pressure. The alcohol and/or ethyl acetate are obtained by fractional separation.
