石油化工

(1)石油的成分
石油不是一种单纯的化合物，它主要是烷烃、环烷烃、芳香烃的混合物，大部分是液态烃，同时在液态烃里溶有气态和固态烃。
(2)石油的炼制
①分馏。是利用石油混合物中各组分沸点的不同，用加热蒸发使各组分气化后，分步冷凝，经常压和减压两阶段分馏，分别得到不同沸点范围的馏分(溶剂油、汽油、煤油、柴油、润滑油、凡士林、石蜡等)。石油分馏得到的汽油中不含不饱和烃，叫直馏汽油。
②裂化。是在高温或催化剂作用下，使含碳原子个数的大分子碳链断裂，生成符合汽油成分的小分子碳链烃的过程。目的是为了得到作为能源用的燃料油——以汽油为主。这种汽油含大量的不饱和烃，叫裂化汽油。
(3)石化生产
①裂解。是利用比裂化更高的温度，使大分子碳链断裂成短链的气态不饱和烃，提供有机化工原料，也称为高温裂解。主要产物是乙烯、丙烯、丁二烯，生产中称为“三烯”。
②重整。是把汽油的直链烃在催化剂的作用下调整结构，使其转化为芳香烃和具有支链的烃。一方面是提高汽油的质量、更重要的另一方面是制得芳香烃，提供有机化工原料，主要产物有苯、甲苯、二甲苯，生产中称为“三苯”。
