Abstract
1-Cyclohexyl-butanol-3 is made by hydrogenating beta - (1, 2, 5, 6 - tetrahydrophenyl) - vinyl methyl ketone in the presence of a nickel catalyst, for example at a temperature of 20 to 100 DEG C. and under a pressure up to 2,000 lbs. per square inch. The product may then be esterified or etherified. The beta-(1, 2, 5, 6-tetrahydrophenyl)- vinyl methyl ketone may be prepared by reacting acrolein with 1, 3-butadiene and condensing the 1, 2, 5, 6-tetrahydrobenzaldehyde so produced with acetone in the presence of a strong base. In examples: (1) beta - (1, 2, 5, 6 - tetrahydrophenyl) - vinyl methyl ketone is hydrogenated in solution in ethyl alcohol in the presence of Raney nickel; (2) the product of (1) is esterified by means of propionic anhydride to yield 1 - cyclohexyl - 3 - propionoxy - butane; (3) the product of (1) is etherified by dissolving in ether and adding sodium, and then adding dimethyl sulphate to give 1-cyclohexyl-3-methoxy-butane. Other esters and ethers mentioned are the esters of butyric, acrylic. succinic, phthalic and hexahydrobenzoic acids, and the ethers of ethyl, propyl, butyl, lauryl and benzyl alcohols, phenols, and the polyhydric alcohols such as ethylene glycol, propylene glycol and glycerol.
