Abstract

Способ тонкой очистки изопрена от циклопентадиена нагреванием изопрена-сырца с ненасыщенным оксосодержащим соединением и дистилляцией смеси с получением очищенного продукта в виде дистиллята и остатка перегонки, содержащего примеси, отличающийся тем, что, с целью повышения глубины извлечения циклопентадиена, в качестве оксосодержащего соединения используют 0,001 - 1,0 мас.% бензохинона на изопрен-сырец при 20 - 60C в течение 0,5 - 4,5 ч.The method of fine purification of isoprene from cyclopentadiene by heating raw isoprene with an unsaturated oxo-containing compound and distilling the mixture to obtain a purified product in the form of a distillate and a distillation residue containing impurities, which use, 1.0% by weight of benzoquinone on raw isoprene at 20 - 60 ° C for 0.5 - 4.5 hours.
