乙烯法冰醋酸在市场中的角色变换

从成本、效益、产品在生命周期中的阶段等方面，将乙烯氧化法和甲醇羰基化生产的冰醋酸在市场中的地位进行了比较。得出了乙烯法的冰醋酸虽然在一定时期内和一定的条件下，还将存在于市场之中，但已从主角转变为配角的结论。并提出了相应的对策。

The Market Role Change of the HAc Made by Ethylene Oxidation

From the cost,the benefit,the life cycle stage of the producetion,We compared the method made by ethylene oxidation with carbiol carbonylation in the process of HAc production .We drew a conclusion that in a period of time and special condition,the HAc made by ethylene oxidation will still exist in the market,but it will change from the protagonist to the stooge.Therefor we give some good suggestion in this article.
