摘　　要：草酸作为一种重要的化工原料,广泛用于药物生产、高分子合成、稀土元素提取以及织物漂白等工业,需求量日趋增加。草酸的合成方法有很多种,文章介绍了多糖氧化法、丙烯氧化法、乙二醇氧化法、一氧化碳偶联法、甲酸钠法,评述了各种方法的优缺点,并对我国草酸工业的发展提出了建议。Oxalic acid as an important chemical raw material, widely used in drug production, polymer synthesis, as well as the extraction of rare earth elements and fabric bleaching industry. The demand of oxalic acid was increasing. There were many kinds of oxalic acid synthesis methods. Polysaccharides oxidation, oxidation ofpropylene, ethylene glycol oxidation, co coupling, sodium formate method, etc. The above synthesis methods were introduced and their advantages and disadvantages compared. Suggestions were advanced as to how to develop the oxalic acid industry in China.
