异戊二烯异戊二烯isoprene一种共轭二烯。分子式CH2=C(CH3)CH=CH2又称2-甲基-1,3-丁二烯。无色液体。熔点-146℃,沸点34℃,相对密度0.6810(20/4℃)。不溶于水,能与乙醇、乙醚、丙酮和苯等溶剂混溶。容易自身聚合或与别的不饱和化合物共聚合。在齐格勒催化剂存在下聚合,生成顺-1,4-聚异戊二烯,其结构和性能相当于天然橡胶;少量异戊二烯与异丁烯共聚,生成丁基橡胶。从植物中得到的一些化合物的分子式为C5H8的倍数,有的化合物热解时生成异戊二烯。工业上由异戊烷或甲基丁烯的催化去氢生产;或从轻油裂化生产乙烯的副产物中提取;或用丙烯合成。丙烯在三烷基铝存在下二聚,生成的2-甲基-1-戊烯在酸性催化剂存在下异构化为2-甲基-2-戊烯,后者热解生成异戊二烯和甲烷。
