Abstract
Process for the production of a mixture of olefinic hydrocarbons suitable for copolymerization with ethylene and propylene, characterized in that it comprises: (a) distilling a fraction of pyrolysis gasoline derived from a cracked hydrocarbon feed, to produce a distillate which boils in the range of 10 to 80ºC and comprising piperylene and isoprene; (b) redistilling said distillate to produce an "isoprene concentrate" and a "piperylene concentrate"; and (c) heating said "piperylene concentrate" to a temperature in the range of 120 to 250º c.
