霜脲氰制备

1.N-乙基脲、氰乙酸和乙酸酐反应得N-氰乙酸基-N-乙基脲，N-氰乙酰基-N-乙基脲再与亚硝酸钠反应1h得到2-氰基-2-肟基乙酰胺钠盐。在2-氰基-2-肟基乙酰胺钠盐中，缓缓加入硫酸二甲酯，同时不断地用50% NaOH溶液调节pH值，使pH值保持7-8反应得到霜脲氰。

2.N-氰乙酰基-N-乙基脲的制备 将N-乙基脲98g、氰乙酸94g和乙酸酐200g混合液，搅拌下升温至60℃，在此温度下保持3h， 停搅拌，静置，析出结晶，减压（78℃/90.4×103Pa)脱去乙酸。再添加130mL水，蒸出残存的酸，抽滤，水洗，干燥，得白色细针状结晶，熔点173℃。
2-氰基-2-肟基乙酰胺的制备 将甲醇125g、水125g、N-氰乙酰基-N-乙基脲77g、亚硝酸钠36g在氮气气流下于40℃反应1h，再加6mol/L盐酸18g，使pH值5.3左右，继续在40℃反应2h，然后加入50%NaOH溶液7g，调节pH值至7～8。此产品在溶液中以钠盐形式存在。
3.霜脲氰的合成 在上述反应物中，缓能动加入硫酸二甲酯75g，同时不断地用50%NaOH溶液调节pH值，使pH值保持7～8，于40℃反应2h，冷却至5℃，抽滤、水洗、干燥，再在无水乙醇中重结晶。
