2，2－二甲基丙酸合成方法的研究

Study on Synthesis of 2, 2-Dimethylpropanoic Acid

本文研究了异丁醇和甲酸在发烟硫酸作用下制备２，２－二甲基丙酸的方法，显著地降低了硫酸的用量并相应缩小了反应体积及废酸的产量。同时时反应温度、物料配比、操作方式等条件进行了探讨。

This paper discusses the synthesis of 2, 2-dimethylpropanoic acid withisobutanol and formic acid in the presence of oleum. The sulfuric acid amount is obviously decreased. The reaction volume and amount of waste acid is reduced. The affection of the factors is studied such as temperature, material ratio and operation manner.
