石油化学工业，简称石油化工。一般指以石油和天然气为原料的化学工业。范围很广，产品很多。原油经过裂解（裂化）、重整和分离，提供基础原料,如乙烯、丙烯、丁烯、丁二烯、苯、甲苯、二甲苯、萘等。从这些基础原料可以制得各种基本有机原料如甲醇、甲醛、乙醇、乙醛、醋酸、异丙醇、丙酮、苯酚等。Petroleum chemical industry, abbreviated as petrochemical industry. Generally refers to the chemical industry that uses petroleum and natural gas as raw materials. The scope is very broad and there are many products. Crude oil undergoes cracking (cracking), reforming and separation to provide basic raw materials such as ethylene, propylene, butene, butadiene, benzene, toluene, xylene, naphthalene, etc. From these basic raw materials, various basic organic raw materials such as methanol, formaldehyde, ethanol, acetaldehyde, acetic acid, isopropanol, acetone, phenol, etc. can be produced.
