二甲苯二甲苯xylene一种芳烃。分子式C8H10。存在于煤焦油和某些石油中。二甲苯有三种异构体,即邻、间和对二甲苯:无色液体。邻、间和对二甲苯的熔点分别为-25.2℃、-47.9℃和13.3℃,沸点分别为144.4℃、139.1℃和138.3℃,相对密度分别为0.8802(10/4℃)、0.8642(20/4℃)和0.8611(20/4℃)。不溶于水,能与乙醇、乙醚等有机溶剂混溶。对、间和邻二甲苯催化氧化,分别生成对、间苯二甲酸和邻苯二甲酸酐;间二甲苯硝化和还原后生成4,6-二甲基-1,3-苯二胺。这些产品是生产纤维和树脂的原料。工业上二甲苯主要由石脑油重整产物中的C馏分提取。工业二甲苯中含间二甲苯50%~60%(体积),邻和对二甲苯各20%~25%(体积)。邻二甲苯的沸点较高,可以用分馏法分离提纯;对二甲苯的熔点最高,可以用分步结晶法提纯;分出对二甲苯后的剩余物再经分馏,可得纯度为85%~90%的间二甲苯。二甲苯可直接用作溶剂,或加在汽油中以提高其抗爆性能。对苯二甲酸与乙二醇聚合生成聚对苯二甲酸乙二酯,为涤纶纤维的原料;邻苯二甲酸酐是制造多种染料和指示剂的原料。
