环戊二烯易于二聚成双环戊二烯(DCPD),而DCPD在高温情况下又可解聚成CPD。环戊二烯(CPD)是一种合成香料的中间体,可以分别与异亚丙基丙酮、丙烯醛、2-丁烯二醇与异丁醛、乙烯基吡啶、5-甲基-2-环己基烯酮、2-己烯醛、环氧戊烯等合成出近百种香料。国内DCPD的主要生产商有大庆华科股份有限公司、辽阳石油化纤公司、上海金森石油树脂公司、苏州联胜化学有限公司等。其中,辽阳石油化纤公司生产的DCPD,纯度为85%,主要出口欧洲。
Cyclopentadiene tends to dimerize into dicyclopentadiene (DCPD), whereas DCPD can be depolymerized to CPD even at high temperatures. Cyclopentadiene (CPD) is an intermediate for the synthesis of perfumes and can react with mesityl oxide, acrolein, 2-butenediol and isobutyraldehyde, vinylpyridine, 5-methyl-2- Cyclohexyl ketene, 2-hexenal, epoxy pentene and other synthetic nearly a hundred kinds of spices. Domestic DCPD major manufacturers are Daqing China Branch Co., Ltd., Liaoyang Petrochemical Company, Shanghai Jinsen petroleum resin company, Suzhou Lian-Sheng Chemical Co., Ltd. and so on. Among them, Liaoyang Petrochemical Company produced DCPD, purity of 85%, mainly exported to Europe.
