摘要
研究了一种合成4-胍基丁酸的方法。原料4-氨基丁酸和氧甲基异脲硫酸盐的化学计量比为1:1.05,胍基化的反应温度35℃,反应时间5~6h,反应过程pH值控制在11~12之间。
The synthesis of 4 - Guanidiobutyric acid was introduced. The optimization reaction conditions involved the stoiehiometric ratio of 4 -aminobutyrie acid and o -methyl -isourea sulfate was 1:1.05. the reaction temperature for gunidiantion was at 35 ℃, time 5 -6 h and pH valel2.
