摘要
研究了在水介质中常压免添加剂由碱式碳酸锌与硬脂酸直接反应清洁合成硬脂酸锌,结果表明:反应温度、反应物料液-固比对合成反应速率有较明显的影响,合成优等品硬脂酸锌的适宜工艺条件为:反应温度80℃,反应物料液-固比7∶1,反应时间30min。
The clean synthesis of zinc stearate by reaction of basic zinc carbonate with stearic acid in water under atmospheric pressure without any additive was studied. It was shown that the rate of the synthetic reaction was affected quite obviously by the reaction temperature and liquid-solid ratio of the feed. And the optimum technical conditions for the first rate product of zinc stearate were as follows： reaction temperature 80℃, liquid-solid ratio of the feed 7：1, reaction time 30 min.
