补充资料:骨粒浸酸
分子式:
CAS号:

性质:即骨粒脱矿(demineralization for bone chip)。用适当浓度的酸液浸渍骨粒,使所含的矿物质(主要是磷酸钙、氟化钙、碳酸钙和磷酸镁等)转化成水溶性盐类从骨粒中溶出,以制取符合明胶生产工艺要求的纯净骨素。实际生产中多采用逆向浸酸过程,即开始阶段使用酸液浓度较低的乏酸液,随着骨粒内矿物质含量的减少逐步提高酸液浓度,在浸酸即将完成时用新鲜酸液浸泡,以避免形成难溶的磷酸氢钙(CaHPO4),降低骨素中残留矿物质含量,减少酸液消耗量,提高供回收的乏酸液中的磷酸盐含量。骨明胶生产工艺中不宜使用整块大料骨浸酸,以避免因浸酸时间过长影响出胶率和从乏酸水中分离磷酸氢钙的困难。
