Because the carbonyl in its structure is with strongly absorb-electron effect, so it is a kind of non-proton polarity solvent with high boiling point, high flash point and low melting point, use conveniently for many processing operation such as filtration, distillation, solvent extraction, and so on; it is with very low toxicity, so the harm to human body is inappreciable, and reduce the environment pollution; due to its very strong dissolvability, it can dissolve organic matter, inorganic matter, resin, polymer, etc., and activate all kinds of reagent, mix to dissolve the other high boiling point solvents; it is with very good stability, it is stable under the hot strong alkali and acidity condition, it is with water-resistance and light, oxygen stability.

246℃ m.p：—20℃闪点121℃ flash point： 121℃分子式：C6H12N2O molecular formula： C6H12N2O 分子量128.18 molecular weight： 128.18 二、DMPU的化学性质 Chemical character of DMPU 其结构中由于羰基具有强烈的吸电子效应，因而它是一种非质子的极性溶剂，具有高沸点、高闪点、低熔点，在过滤、蒸馏、溶剂萃取等工艺操作中使用方便；毒性极低，对人体危害微不足道，也减少了对环境的污染；由于它具有极强的溶解性，能溶解有机物、无机物、树脂、聚合物等，并对各种试剂具有活化性质，还能与其它高沸点溶剂混溶；具有极好的稳定性，在热的强碱和酸性条件下都很稳定，还具有耐水性及对光、氧的稳定性。
