Abstract

Improvements introduced in the object of the Main Patent nº 395,516, granted on July 12, 1973, by: Procedure for the production of a mixture of olefinic hydrocarbons suitable for copolymerization with ethylene and propylene, comprising (a) distilling a fraction of pyrolysis gasoline derived from a cracked hydrocarbon feed, to produce a distillate that boils in the range of 10 at 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 250ºC; characterized in that in the aforementioned step (c) the "piperylene concentrate" is heated at a temperature higher than 250ºC to 350ºC inclusive, to produce said mixture.
