摘要
以丙酸钙和硫酸锌为原料,经分解反应合成了一种新型食品添加剂一丙酸锌,此反应的优化条件是:n（丙酸钙）:n（硫酸锌）=1.16:1,c（丙酸钙）=1.075mol/L,c（硫酸锌）=1.239mol/L,反应温度为80℃,反应时间为40min.丙酸锌产率可达93.6％,其各项技术指标经检测符合同类产品食品级标准要求。
The synthetic conditions of zinc propionate with calcium propionate and zinc sulfate as raw materials were studied. The experimental results showed that optimum conditions were as follows: n (calcium propionate): n(zinc sulfate) = 1. 16: 1, C(calcium propionate) = 1. 075mol/L, C(zincsulfate) = 1. 239mol/Land the reaction time at 80℃ , 40min. Under the above - mentioned conditions, the yield of zinc propionate could reached 93. 6% and the product quality was in accordance with the demands for food industy.
