Abstract

1,138,126. Dimerization. ESSO RESEARCH & ENG. CO. 4 Aug., 1967, No. 35868/67. Heading C5E. C 4-6 conjugated dienes are dimerized, or are co-dimerized with an ethylenically unsaturated compound, by a continuous process in which the feed is introduced into a gas-liquid reaction zone maintained at conditions of temperature and pressure such that the diene is gaseous within the zone, an inert liquid solvent being passed countercurrent to the feed, and the desired dimer being recovered as a solution in said solvent, from which it may be separated. Suitable reaction zones are gas absorption towers and distillation columns. The solvent preferably boils at least 15‹ F. above the b.p. of the desired dimer to facilitate separation, a paraffinic wash oil of b.p. 420‹ F. being mentioned. The process is illustrated by the dimerization of butadiene to vinyl cyclohexene (plus some 1,5-cyclooctadiene), and the codimerization of butadiene and ethylene to cyclohexene. Other monomers mentioned are the dienes piperylene, isoprene and cyclopentadiene, and the ethylenic compounds propylene and maleic anhydride.
