苊

苊用途

【用途一】
是生产1,8-萘二甲酸酐的原料，可经脱氢后制苊烯树脂，可用于制染料、植物生长激素、杀虫杀菌剂等
【用途二】
有机合成原料，经硝化可制硝基苊；进一步氧化可制1,8-萘二甲酸酐和苊醌，可用于合成染料、聚酯树脂、聚酯纤维；还可用于制荧光颜料，药品，杀虫剂等。苊脱氢得苊烯，可制苊烯树脂。
【用途三】
生产 1.8- 萘二甲酸酐的原料，用于制染料，可经脱氢后制苊稀树脂，可制植物生长激素杀虫杀菌剂等。苊与苦味酸生成橙色针状结晶(熔点162℃)。可发生伯奇还原(Birch reduction)，得2a，3-苊(2a，3-acenaphthene)。用Pd/C脱氢氧化得苊烯(acenaphthylene)。用高锰酸钾氧化得1,8-萘二甲酸酐。亲电取代反应主要发生在5-位，如溴化、硝化、烷基化。在四氯化碳中与N-溴代琥珀酰亚胺(NBS)作用得1-溴取代物。存在于煤焦油中。实验室用1,8-二溴甲基萘与苯基锂作用制备。用于有机合成。本品有刺激性。
