补充资料:甲醛
甲醛 formaldehyde 最简单的醛,分子式HCHO。无色气体。熔点-92℃,沸点-21℃,相对密度0.815(20/4℃)。有强刺激性气味。易溶于水,溶于乙醇、乙醚等有机溶剂。与空气混合易爆炸,爆炸极限7%~73%(体积)。甲醛的化学性质活泼,稀甲醛水溶液中的甲醛几乎全部转化成其水合物甲二醇。较浓的甲醛水溶液(如一般的福尔马林)经较长时间的放置或使之慢慢蒸发,则聚合成多聚甲醛,n=6~50。如果将含2%硫酸的60%的甲醛溶液进行蒸馏,则生成三聚甲醛。三聚甲醛的熔点为61~62℃,具有环状结构,不呈还原性,在酸性条件下能解聚 。多聚甲醛则要加热才能解聚,因此多聚甲醛可以作为单体甲醛的储存形式。甲醛具有很强的化学还原性,还能与含亲核基团的试剂进行加成缩合反应。 甲醛在工业上通常是用甲醇在银催化剂存在下进行空气氧化或催化脱氢制得;也可由甲烷或天然气的丙烷丁烷混合气在各种金属氧化物催化剂存在下进行空气氧化制得。甲醛是重要的工业原料和试剂,主要用作合成树脂、染料、药物、试剂和多种化工产品。市售的福尔马林是40%甲醛的水溶液,可用作消毒剂和防腐剂。 |
