补充资料：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。 |
