摘要

The raw material is prepd. by preheating a 5 chain carbon stream which is distilled from a cracked naphtha or gas oil, for not >5 hrs. to a temp. above 160 (160-230) degrees C esp. for 0.05-1.5 hrs. to 170 degrees C, and adding, before or after preheating, butene-1, butene-2, isobutene or butadiene raffinate in an amt. is not >20 wt.%.
