General description
对二甲苯是二甲苯的异构形式。它在沸石（催化剂）存在下与各种酸发生 Friedel-Crafts 酰化反应。它可以从分离自石脑油的石脑油馏分的二甲苯和乙苯的异构形式的混合物中制备。而且，在 ZSM（Zeolite Socony Mobil）-5 催化剂作用下，从甲苯可制备对二甲苯。它是用于制造 PET（聚（对苯二甲酸乙二醇酯））瓶的原料。据报道，在沸石催化剂存在下，它可由乙烯和二甲基呋喃可持续地合成。
Application
对二甲苯可用于合成聚对二甲苯和对苯二甲酸。
对二甲苯可用于蔬菜中有机氯农药的单滴微萃取，通过气相色谱（GC）与质谱（MS）联用进行分离。
