semicarbazide

This thesis mainly introduced that ureas and semicarbazides were synthesized by oxidation of corresponding thioureas and thiosemicarbazides using 30% peroxide as oxidant.

本文主要介绍了以30%浓度的双氧水作为氧化剂氧化硫脲、氨基硫脲来制备相应的脲和氨基脲类化合。

A new convenient and general one-step route for preparing azines by treating aromtic aldehydes and semicarbazide with anhydrous zinc chloride as catalyst is described.

广泛的化合,如作染料,光敏质,聚合单体,另外它们还加成反应的母体化合。
