一种环境友好的聚乙二醇药用辅料精制工艺

摘要

与传统方法相比,采用阳离子交换树脂精制聚乙二醇药用辅料,可彻底消除废水和废固给企业带来的环保压力,降低能耗,提高产品的收率;同时,该法可有效脱除产品中残留的金属离子,产品的色泽浅、纯度高,质量指标完全符合中国药典2010年版的要求.%Compared with traditional methods, the purification method of excipients polyethylene glycol using cation exchange resin can completely eliminate the enterprise's environmental pressure brought by waste water and sol-id waste, and reduce energy consumption, improve product yield. Meanwhile, this method can be effective removal of residual metal ions in the product, light color and high purity product. And all quality indicators compliance with the standard of Chinese Pharmacopoeia 2010 edition.
