The kinetics of the reaction of malononitrile with (+) 3-methyl-cyclohexanone were studied in benzene at 25° in the presence of triethylamine or piperidine, either alone or together with acetic or benzoic acid. The rate law of the reaction was found to be: v = k (Amine) (Ketone) (Nitrile). It is interpreted in terms of a basic catalysis by the amine. When amine-acid mixtures were used, a general acid
研究了丙二腈与(+)3-甲基-环己酮在25°下在苯中在三乙胺或哌啶的存在下(单独或与乙酸或苯甲酸一起)反应的动力学。发现该反应的速率定律是:v=k(胺)(酮)(腈)。根据胺的碱性催化来解释。当使用胺-酸混合物时,观察到一般的酸催化作用,但是它对反应总速率的影响很小,因为酸还降低了游离胺的浓度。
