乙苯上游产品

乙苯下游产品

4.液相烷基化法通常是在常压、85-90℃下，采用三氯化铝为催化剂，使乙烯与苯反应生成乙苯。副反应是乙苯进上步被乙烯烷基化生成多乙苯。工业上将苯的转化率限制在52-55%在右，并采用高的苯-乙烯摩尔比（一般为2左右），以防止生成更的二乙苯与多乙苯。乙苯的平均收率为94-96%。

5.气相烷基化法最初是乙烯和过量的苯在磷酸-硅藻土上蔌氧化铝-硅胶催化剂作用下，于300℃、4-6兆帕下进行气相烷基化反应制取乙苯。由于所采用的催化剂不能进行多乙苯的脱烷基，故多乙苯无法处理。虽然通过增加苯的配料比减少多乙苯的生成，但却增加了循环苯的蒸馏成本。

6.由C8芳烃分离制乙苯催化重整所制得的芳烃。经分离除去苯和甲苯后，混合二甲苯馏分各组分的沸点很接近，用精馏的方法分离乙苯需用300-400块塔板，回流比为75。另外也可采用吸附分离和色层分离理到乙苯。由于从C8芳烃分离乙苯在经济上已无法与苯烷基化乙苯相竞争，并且新一代贵金属异构化催化剂能有效地将乙苯转化成二甲苯，从而使乙苯分离的重要性大大下降。
