摘　　要：本文以硬脂酸和氢氧化钙为原料,双氧水和乙醇为复合催化剂,实现了在水介质中绿色清洁合成硬脂酸钙.考察了双氧水用量、乙醇用量、反应温度、固液比和反应时间等因素对反应的影响.结果表明,在双氧水用量24%、乙醇用量10%、反应温度60℃、固液比1∶15、反应时间3 h的优化条件下,产品的游离酸含量为0.28%.生产后的滤液可进行重复使用,避免了废水的排放.工业放大实验结果表明,此方法可沿用现有复分解法设备进行工业化生产.In this paper, calcium stearate was environmentally synthesized from stearic acid and calcium hydroxide using hydrogen peroxide and ethanol as composite catalyst in aqueous media. Effects of hydrogen peroxide dosage, ethanol dosage, temperature, solid-liquid ratio and time on the reaction were investigated. The results showed that free acid of product was 0. 28% under the optimal conditions of 24% hydrogen peroxide, 10% ethanol and solid-liquid ratio 1：15 at 60℃ within 3 h. This route realized sewage zero emissions since the filtrate can be reused. According to the results of industrial scale-up, calcium stearate could be industrially prepared by this method using the original production equipment in the double decomposition.
