It is best known as its lithium derivative of its conjugate base, lithium diisopropylamide, known as "LDA". LDA is a strong, non-nucleophilic base. Diisopropylamine can be dried by distillation from potassium hydroxide (KOH) or drying over sodium wire.〔Armarego, W. L. F. and Perrin, D. D. ''Purification of Laboratory Chemicals'' 4th Ed. pg 186, Butterworth and Heinemann: Boston, 1996.〕 ==Reactions and uses== Diisopropylamine is primarily used as a precursor to two herbicides, diallate and triallate, as well as certain sulfenamides used in the vulcanization of rubber.〔Karsten Eller, Erhard Henkes, Roland Rossbacher, Hartmut Höke "Amines, Aliphatic" Ullmann's Encyclopedia of Industrial Chemistry, 2000, Wiley-VCH, Weinheim. 〕 It is also used to prepare N,N-Diisopropylethylamine (Hünig's base) by alkylation with diethyl sulfate. The bromide salt of diisopropylamine, diisopropylammonium bromide, is an organic molecular solid whose crystals are ferroelectric at room temperature. This renders it a possible more biospherically inert alternative to barium titanate. == Preparation == Diisopropylamine is commercially available. It may be prepared by the reductive amination of acetone with ammonia using a modified copper oxide, generally copper chromite, as a catalyst: : + 2 + 2 → + 2 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「diisopropylamine」の詳細全文を読む スポンサード リンク
