Abstract The reactions of 4-methyl- o -benzoquinone in the presence of l -proline were studied by rapid scanning spectrophotometry. It was concluded that it was transformed into 5-methyl-4- N -propyl- o -benzoquinone, according to the equation: 2(4-methyl- o -benzoquinone) + l -proline → 4-methylcatechol + 5-methyl-4- N -prolyl- o -benzoquinone. Rate constants for the reaction of 4-methyl- o -benzoquinone
摘要 采用快速扫描分光光度法研究了4-甲基-邻苯醌在l-脯氨酸存在下的反应。得出的结论是,它被转化为 5-甲基-4-N-丙基-邻苯醌,根据方程式:2(4-甲基-邻苯醌)+l-脯氨酸→4-甲基儿茶酚+5-甲基- 4-N-脯氨酰-邻苯醌。已经测量了 4-甲基-邻苯醌与水和 l-脯氨酸反应的速率常数。
