Pn is the simplest chiral diamine. The molecules exists as a colorless liquid at room temperature. ==Preparation== Industrially, this compound is synthesized by the ammonolysis of 1,2-dichloropropane: This preparation allows for the use of waste chloro-organic compounds to form useful amines using inexpensive and readily available ammonia:〔 :CH3CHClCH2Cl + 4 NH3 → CH3CH(NH2)CH2NH2 + 2 NH4Cl The racemic mixture of this chiral compound may be separated into enantiomers by conversion into the diastereomeric tartaric acid ammonium salt. After purification of the diastereomer, the diamine can be regenerated by treatment of the ammonium salt with sodium hydroxide. Alternate reagents for chiral resolution include N-p-toluenesulfonylaspartic acid, N-benzenesulfonylaspartic acid, or N-benzoylglutamic acid. 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「1,2-Diaminopropane」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.
