多聚甲醛

多聚甲醛用途

【用途一】
多聚甲醛为高甲醛含量的固态甲醛，呈固体颗粒状、便于贮存和运输。在较高的温度下能变成甲醛蒸气，易于代替高浓度甲醛参与各种反应，有利于化工、制药等化学合成及其他工业领域的应用，特别是在要求使用无水甲醛作原料的合成方面，用途广泛。主要有以下几方面
（1）农药：合成乙草胺、丁草胺和草甘膦等；
（2）涂料：合成高档汽车用漆；
（3）树脂：合成脲醛树脂、酚醛树脂、聚缩醛树脂、蜜胺树脂、离子交换树脂等及各种粘合剂；
（4）造纸：合成纸张增强剂；
（5）铸造：翻砂脱膜剂、合成铸造粘合剂；
（6）养殖业：薰蒸消毒剂。
（7）有机原料：用于制备季戊四醇、三羟甲基丙烷、甘油、丙烯酸、丙烯酸甲酯、甲基丙烯酸、N－羟基甲基丙烯酰胺、烷基苯酚、甲基乙烯基酮等。
（8）其他：医药及消毒。
【用途二】
用于制药工业，也用作灭菌剂
【用途三】
用作有机化工、合成树脂的原料，也用作药物熏蒸剂
