| 摘 要： | 以牡蛎壳为原料，从中提取丙酸钙，并对其工艺进行优化。以丙酸钙得率为指标，对不同液固比、壳酸比、反应时间、中和时间下对丙酸钙提取率的影响进行了研究。结果表明：液固比17：1，壳酸比1：1．1，反应时间3．0h，中和时间30min为最佳工艺参数。在此条件下，丙酸钙得率达98．15％，含量达97．71％。

| Abstract: | Oyster shell is the raw material to extract calcium propionate. This extract processes have been optimize. Study has been conducted with calcium propionate as index, with different tests of water/shell ratio, shell-acid ratio, reaction time and neutralization time under different extraction rate of calcium propionate, whose results show that： water/shell ratio 17 ： 1, shell- acid ratio 1 ： 1.1, reaction time 3. 0h, and the neutralization time of 30min was the best process parameters. Under this condition, calcium propionate yield reached 98.15% and content of 97.71%. |
