二十六、丙烯腈 丙烯腈CH_2=CHCN,简称AN;为五色易流动性液体,蒸气有毒;密度0.8060g/cm~3,沸点77.3～77.4℃,凝固点-83～-84℃;稍溶于水,易溶于一般有机溶剂;水解时生成丙烯酸,还原时生成丙腈,易聚合,也能与VAC、VCM等单体共聚。丙烯腈主要用于生产腈纶,也是生产丁腈橡胶(SAN)、丙苯树脂(AS)、丙丁苯树脂(ABS)、丙丙苯树脂(AAS)等合成树脂和合成橡胶的单体。
Twenty-six, acrylonitrile acrylonitrile CH2=CHCN, abbreviated as AN; five-color flow liquid, toxic vapor; density 0.8060g/cm~3, boiling point 77.3 ~ 77.4 °C, freezing point -83 ~ -84 °C; slightly soluble Water, soluble in common organic solvents; generates acrylic acid when hydrolyzed, generates propionitrile when reduced, easily polymerized, and can also be copolymerized with VAC, VCM and other monomers. Acrylonitrile is mainly used for the production of acrylic fiber, and it is also a monomer for the production of synthetic resin and synthetic rubber such as nitrile rubber (SAN), propylbenzene resin (AS), propylbenzene resin (ABS), and acrylic resin (AAS).
