2、乙醛 缩合法、乙醇脱氢法、醋酸乙烯加成法因其热力学上的有利性和经济上的合理性, 被许多中外企业所采用。但基于国情及各方面的因素考虑,本论文采用乙醇脱氢法 生产乙酸乙酯,并用了 ASPEN 模拟进行了物料和热量衡算。 关键词:乙酸乙酯;乙醇脱氢法;工艺设计;ASPEN 模拟;衡算 英文摘要 II ABSTRACT Ethyl acetate (EA) is an important chemical solvent. EA is widly used in applications of coatings, adhesives, pharmaceuticals and printing ink
3、and its synthesis meyhod has get a lot of interests. The traditional synthesis method of EA is esterification, in which EA was made by direct esterification of ethanol and acetic acid with a sulphuric acid catalyst. Aldehyde condensation, dehydrogenation of ethanol and acetate/ethylene addition reac
4、tion are the new technologies developed in recent years. Compared with the traditional synthesis, these new methods have adopted by many Chinese and foreign enterprises because of its favorable thermodynamic and economic rationality. However, based on national conditions and taking into consideration various aspects, this thesis used Ethanol dehydrogenation was
