乙醛肟制备

乙醛肟由羟胺和乙醛水溶液反应而得。反应方程式：CH₃CHO+NH₂OH·HCl+NaOH→CH₃CH=NOH+NaCl+H₂O
在目前的工业生产中，普遍采用含量较高的晶体硫酸羟胺作原料，在使用时再将其配制成20％～50％水溶液，然后与乙醛反应生成乙醛肟。反应方程式如：CH₃CHO+(NH₂OH)₂·H₂SO₄→CH₃CH=NOH
在上述硫酸羟胺水溶液中加入乙醛，在40～50℃下反应2h，冷却后除去其中的无机盐，得到含乙醛肟约50%的澄清透明水溶液，经检测，该水溶液中除乙醛肟和水外，杂质量非常少，乙醛肟的收率也在90％以上(以硫酸羟胺计)，将这种水溶液进行抽提精制，可以得到含量90%以上的乙醛肟产品。
