1,192,692. Making alcohols. TOKUYAMA SODA K.K. 6 March, 1968, No. 10995/68. Heading C2C. At least one aliphatic or cycloaliphatic olefin having 2-8 C is hydrated using water or steam at 100-300‹ C. to yield the corresponding alcohol in the presence of a solid acid catalyst containing Zr : W : O = 1 : 2-8 : 0À5-3À5. Specified olefins are ethylene, propylene, butene- 1, butene-2, isobutene, pentane, hexene, heptene, octene and cyclohexene. The type of alcohol produced will depend on the location of the double bond, e.g. propylene will yield isopropyl alcohol, butene-2 and octene-1 yielding secondary alcohols. Examples describe the preparation of ethyl and isopropyl alcohols.
