乙酸乙酯供需动态与工艺技术进展

本文简述国内外乙酸乙酯供需动态。西欧和东亚供应不足，要从有多余乙酸乙酯供应量的拉丁美洲和日本输入，并需要增加乙酸乙酯产能。文章介绍了乙烯－乙酸乙酯新工艺，并同乙酯－乙醇酯化和乙醛缩合制乙酸酯工艺作比较，阐明新工艺是乙酸乙酯生产中技术先进、经济效益高的生产方法。

Supply/Demand Trend and New Process of EA

This paper briefly describes supply/demand trends ethyl acetate(EA) at home and abroad. On West Europe and East Asia malketplaces, EA supplies are no enough, must be import from Latin America and Japan, and must be increase capacities. The article introduces new process to prepare EA through ethylene and acetic acid addition. Compares with the process to produce EA from acetic acid and eth-anol esterification and acetaldehyde condensation. The paper clarifies that the new process is an advanced one with good economic benefit among the processes to produce EA.
