Malononitrile is relatively acidic, with a pKa of 11 in water.〔(Evans pKa table )〕 This allows it to be used in the Knoevenagel condensation, for example in the preparation of CS gas: In related chemistry, malononitrile is a suitable starting material for the Gewald reaction, where the nitrile condenses with a ketone or aldehyde in the presence of elemental sulfur and a base to produce a 2-aminothiophene. ==See also== * Malonic acid * Diethyl malonate 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「malononitrile」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.
