日本川研精细化学公司一直从事特种高沸点极性溶剂1,3-二甲基-2-咪唑啉酮的开发。该公司最近宣布,用改性催化剂可大幅度缩短其制造过程和降低成本,因此该公司决定以此为转折点,全力扩大该溶剂的生产。1,3-二甲基-2-咪唑啉酮为五元环结构是尿素的衍生物。由于采用新的改性催化剂,可使工艺更为合理。1,3-二甲基-2-咪唑啉酮不但安全性高,而且也是稳定性极佳的非质子性极性溶剂,加之极性大,能完全溶于水和所有的有机溶剂,同时对无机物和有机物的溶解性也大,即
Japan Chuanyan Fine Chemical Co., Ltd. has been engaged in the development of a special high boiling point polar solvent 1,3-dimethyl-2-imidazolidinone. The company recently announced that the use of modified catalysts can significantly reduce its manufacturing process and reduce costs, so the company decided to use this as a turning point to fully expand the production of the solvent. 1,3-dimethyl-2-imidazolidinone is a derivative of a five-membered ring structure that is urea. Due to the use of new modified catalysts, the process can be made more rational. 1,3-Dimethyl-2-imidazolidinone is not only highly safe, but also an aprotic polar solvent with excellent stability. It is polar and can dissolve completely in water and all organic solvents. The solubility of inorganics and organics is also large, ie
