查询词典 glycolic acid

The preparation of polymer is required for high purity of glycolic acid, if not, low-weight polymer is obtained, therefore, high purity glycolic acid is scarce in the market. So, the research for the synthesis of glycolic acid is essential. In domestic and overseas, there are many methods for preparation of glycolic acid, including glycin oxidation, cyanogenesis, aldehyde oxidation, coupling of maldehyde and methyl formate, oxalic acid electrolysis, chloroactic acid hydrolysis and so on.

制备羟基乙酸的聚合物时，对羟基乙酸单体的纯度要求较高，否则得到的聚合物分子量较低，导致高纯度羟基乙酸的需求量逐年增长，目前在国内，高纯度的羟基乙酸还没有形成工业化规模生产，对羟基乙酸的合成进行研究是非常有意义的。
