Abstract
1,172,858. Tetrahydroindenes. IMPERIAL CHEMICAL INDUSTRIES Ltd. 27 April, 1967 [24 May, 1966], No. 23152/66. Heading C5E. [Also in Division C3] One or more C 10 non-conjugated dienes having 4,7,8,9-tetrahydroindene structures, i.e. compounds of the formula where each R 1 , R 2 , R 3 and R 4 is a hydrogen atom or an alkyl group and preferably at least one of R 2 and R 3 is a methyl group are obtained by heating a cracked hydrocarbon stream containing cyclopentadiene and at least one other C 5 diene at a temperature of from 150 to 300 C. and a pressure of from 50 to 1000 1bs./sq. inch whereby a Diels-Alder reaction takes place and a mixture is formed containing compounds of the desired formula from which individual compounds may be isolated. The hydrocarbon stream may be obtained from the overheads from a depentanizer of a distillation unit for cracked naptha, or from the bottoms in a debutanizer in the same distillation train. The cracked hydrocarbon stream may also be obtained from by-products in the natural gas, gas, coal-tar and petroleum industries.
