Abstract

Oily polymerization products of butadiene and its homologues are produced by heating the initial hydrocarbon to about 400 DEG C. or higher at ordinary pressure, with or without a catalyst. In the Examples (1) butadiene is passed through an iron tube filled with iron turnings at 400-500 DEG C., the issuing vapours being passed into a condenser preferably at 50 DEG C. when an oil mainly consisting of vinylcyclohexenes boiling at 110-135 DEG C. condenses; instead of iron, other metals such as aluminium, copper, or nickel may be used, also nonmetallic catalysts: (2) butadiene is passed over nickel supported on pumice at 400-500 DEG C., the greater part of the condensate being vinylcyclohexenes, but a fraction boils above 200 DEG C., especially when the speed is low and the temperature about 500 DEG C.: (3) butadiene is passed through an aluminium tube containing aluminium splinters, yielding vinylcyclohexenes: (4) butadiene is passed in a strong current through a glass tube filled with glass wool at 430-450 DEG C.: (5) butadiene is passed slowly at 430-450 DEG C. through a porcelain tube containing silica gel: (6) isoprene is passed through a glass tube containing glass wool at 400-430 DEG C., the condensate boiling principally between 165 DEG C. and 180 DEG C. and probably containing dipentene: (7) 1,3 dimethyl butadiene obtained by eliminating water from methyl pentandiol is passed through an iron tube containing iron sponge (from iron carbonyl) at 400 DEG C., the condensate boiling at 195-210 DEG C., or at 13 mm., at 90-100 DEG C. In all cases the unchanged diolefine is separated and returned to the tube.
