protic ionic liquids (PILs) have been studied. For all these PILs, the bacteria toxicity and environmental biodegradability have been investigated, as well as their corrosive behavior and miscibility in different types of lubricating base oils. The PILs studied showed poor to moderate biodegradability (BOD5/COD from 0.072 ± 0.002 to 0.18 ± 0.01) and slight toxicity (TU values between from 1.18 ± 0.04 and
在这项工作中,已经研究了六种不同类型的质子
离子液体(
PIL)。对于所有这些
PIL,已经研究了细菌毒性和环境
生物降解性,以及它们在不同类型的润滑基础油中的腐蚀性和可混溶性。所研究的
PIL显示出较差至中等的
生物降解性(BOD 5 / COD从0.072±0.002到0.18±0.01)和轻微的毒性(TU值在1.18±0.04和2.7±0.1之间)。但是,这些环境性能比工业上使用的参考润滑剂添加剂(ZDDP)获得的环境性能好得多。此外,五个
PIL对钢没有腐蚀作用。只有一种
PIL在作为基础油的酯中显示出某种混溶性,其余混合物则高度不稳定。
