It is a white, water-soluble solid.〔〔 It decomposes upon melting.〔 A number of carbazides are known where one or more N-H groups are replaced by other substituents. They occur widely in the drugs, herbicides, plant growth regulators, and dyestuffs. ==Production== Industrially the compound is produced by treatment of urea with hydrazine:〔Jean-Pierre Schirmann, Paul Bourdauducq "Hydrazine" in Ullmann's Encyclopedia of Industrial Chemistry, Wiley-VCH, Weinheim, 2002. .〕 :OC(NH2)2 + 2 N2H4 → OC(N2H3)2 + 2 NH3 It can also be prepared by reactions of other C1-precursors with hydrazine, such as carbonate esters.〔 It can be prepared from phosgene, but this route cogenerates the hydrazinium salt ()Cl and results in some diformylation. Carbazic acid is also a suitable precursor: :N2NH3CO2H + N2H4 → OC(N2H3)2 + H2O 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Carbohydrazide」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
