TITLE:
摘要: 目的:优化3-羟基-1-金刚烷甲酸的合成工艺。方法:以1-金刚烷甲酸为原料、苄基三乙基氯化铵(TEBAC)为相转移催化剂,在碱性条件下经高锰酸钾羟基化制备得到3-羟基-1-金刚烷甲酸。以收率为指标,采用星点设计-响应面法优化反应温度、反应时间和高锰酸钾-底物的摩尔比。结果:最优合成工艺为反应温度60 ℃、反应时间8.5 h、高锰酸钾-底物的摩尔比为1.28 ∶ 1。收率预测值与实测值的相对误差为2.51%(预测值91.26%,实测平均值为93.61%,n=6);所制3-羟基-1-金刚烷甲酸的平均纯度为99.26%(n=6)。结论:按优化的合成工艺成功制得纯度与收率较高的3-羟基-1-金刚烷甲酸。
ABSTRACT: OBJECTIVE: To synthesize 3-hydroxyadamantane-1-carboxylic acid and optimize its synthesis technology. METHODS: Using 1-adamantane carboxylic acid as starting material, triethyl benzyl ammonium chloride (TEBAC) as phase transfer catalyst, 3-hydroxyadamantane-1-carboxylic acid was prepared by potassium permanganate in alkaline condition. Treating yield rate as index, central composite design-response surface method was conducted to optimize the reaction temperature, reaction time and the mole ratio of potassium permanganate-substrate. RESULTS: Optimized synthesis technology was as follows as reaction temperature 60 ℃, reaction time 8.5 h, mole ratio of potassium permanganate-substrate 1.28 ∶ 1. The deviation for yield rate of prediction value and the measured value was 1.38% (prediction value was 91.26%, the measured average value was 93.61%, n=6); the average purity of prepared 3-hydroxyadamantane-1-carboxylic acid was 99.26% (n=6). CONCLUSIONS: 3-hydroxyadamantane-1-carboxylic acid with high purity and yield rate is prepared successfully by optimized synthesis technology.
