新型环保稀释剂的开发与应用研究

Research on Development and Application of New Type Environmental Diluent

本文研发了一种用于湿法炼铜中的萃取提铜工序的新型环保稀释剂,然后进行了新型环保稀释剂与普通稀释剂(260#煤油)的挥发性、水溶性、萃取性能、混合有机相兼容性的实验室对比试验,开展了新型环保稀释剂应用的工程化试验。结果表明,该稀释剂具有闪点高、比重小、馏程窄、挥发性极低、几乎无气味、不含芳烃毒性成分、极性小等优点,各项萃取性能指标优于普通稀释剂,单耗量低,具备非常好的应用前景。

In this paper,a novel environmental diluent was developed for solvent extraction process of copper hydrometallurgy,laboratory tests were carried out to compare the characteristics of the present new diluent and the ordinary dilute(260#kerosene)in terms of volatility,water solubility,extraction performance and compatibility of mixed organic compounds,and the application test of this new environmental diluent in a solvent extraction plant was carried out.Results showed that the new diluent has the advantages of high flash point,small specific gravity,narrow distillation range,very low volatility,almost no odor,no aromatic toxic components,and low polarity,and the extraction performance index of this new diluent is better than that of the ordinary dilute,and it has less unit consumption and a very good application prospect.
