丙酸钙

丙酸钙用途

【用途一】
用作食品防腐、防霉剂，对霉菌、酵母菌及细菌等具有广泛的抑制作用
【用途二】
用作分析试剂
【用途三】
丙酸钙液湿酸型防腐剂，其抑菌作用受环境PH的影响。在PH5.0时最小抑菌浓度为0.01%，PH6.5时为0.5%。在酸性介质中对各类霉菌、好氧芽孢杆菌或革兰阴性杆菌由较强的抑制作用。对防止黄曲霉菌素的产生有特效，而对酵母几乎无效。此外，也作为食品的防腐剂。
【用途四】
防腐剂；防霉剂。
【用途五】
丙酸钙也是酸型食品防腐剂，其抑菌作用受环境Ph值的影响。在Ph值5.0时最小抑菌浓度为0.01%，Ph值6.5时为0.5%。在酸性介质中对各类霉菌、革兰氏阴性杆菌或好氧芽孢杆菌有较强的抑制作用。对防止黄曲霉菌素的产生有特效，而对酵母几乎无效。在食品工业中，主要用于食醋、酱油、面包、糕点和豆制品，最大使用量(以丙酸计，下同)2.5g/kg；在生面湿制品中最大使用量0.25g/kg。还可作饲料的防霉剂。
【用途六】
用作面包、糕点和奶酪的保存剂和饲料的防霉剂。作为食品保存剂的丙酸盐，丙酸钙主要用于面包，因为丙酸钠使面包的ph值升高，延迟生面的发酵；糕点中多用丙酸钠，因为糕点的膨松采用合成膨松剂，没有pH值上升引起的酵母发育问题。作为饲料保存剂时，丙酸钠的效果优于丙酸钙。但丙酸钙比丙酸钠稳定。丙酸盐在食品中除用于面包、糕点、奶酪等外，还可用于酱油防霉，抑制再发酵作用。在医药中，丙酸盐可做成散剂、溶液和软膏治疗皮肤寄生性霉菌引起的疾病。软膏（液）含12.3%丙酸钠，散剂含15%丙酸钙。
【用途七】
食品、烟草及药物的霉菌和微生物抑制剂。治疗上用于杀真菌剂。丁基橡胶防老剂。

丙酸钙制备

1.氢氧化钙粉末在中和锅中制成悬浮液，加入丙酸中和至pH值7～8，中和温度70~100℃，中和时间2～3h。中和液过滤除去不溶物，清液经浓缩、冷却、结晶、分离、干燥得成品。
CH3CH2COOH[Ca(OH)2]→(CH3CH2COO)2Ca

②用过量蛋壳在常温、常压下与丙酸反应3h，经过滤、浓缩，在120℃烘干得鳞片状白色无水丙酸钙晶体，其产率可达97%以上。

③在反应器中将CaO和一定量水混合，制成浓度为1.0～1.3mol/L的石灰乳，然后在70～95℃不断搅拌下，缓慢将浓度为12～13mol/L丙酸（过量50%）溶液加入，继续搅拌30min至溶液澄清得丙酸钙溶液。控制pH值为7～8，待冷却后过滤，除去不溶物，滤液移入蒸发器，浓缩得白色粉末状丙酸钙，再在干燥箱中于120～140℃烘干脱水，得白色粉状无水丙酸钙产品。

2.由丙酸与氢氧化钙中和，经浓缩、结晶、分离、干燥而得。

3.将氢氧化钙调成悬浮液，加入丙酸反应，反应物料经过滤、干燥即可
