摘要：
应用强酸性阳离子交换树脂催化,使甲醛与甲醇反应生成甲缩醛,可除去乙二醛水溶液中75％的甲醛,而不改变乙二醛的含量。此法简便可行,树脂无需再生,可重复使用多次,与乙二醛水溶液分离处理容易。
Abstract：Up to 75% of formaldehyde in glyoxal aqueous solution- was removed by the reaction of formaldehyde with methanol catalyzed by the cation exchange resins to form methylal. The content of glyoxal kept unchanged. It is not neccessary to regenerate the resins in the reuse as catalysts which were separated readily from glyoxal solution.
