乙炔制备草酸的实验研究

Study on the Preparation of Oxalic Acid from Acetylene

:研究了一种新颖的乙炔氧化制备草酸的方法 ,系统地考虑了催化剂种类、用量、硝酸初始质量分数和反应温度的影响。结果表明 ,催化剂以 Hg( NO3) 2 为最佳 ,随用量的增加 ,草酸产量随之增加 ;硝酸初始质量分数的增加也使草酸产量增加 ;反应温度为 30～ 40℃时草酸产量最大。

An unique synthesis of oxalic acid from acetylene by oxidation was studied.The results show that Hg(NO 3) 2 is the best catalyst.The more Hg(NO 3) 2 is used,the more oxalic acid is produced.With increasing the initial concentration of nitrate,the productivity is also increased.The best reaction temperature is about 30～40℃.
