二甲基甲酰胺(Dimethylformamide,简称DMF)为无色液体,结构式:分子量:73.09,沸点:153℃,易溶于水和有机溶剂。它是一种良好的溶剂,已广泛应用于纤维、涂料、高分子合成及电影胶片等工业中。可经呼吸道、消化道和完整皮肤侵入机体,主要损害肝脏,属中到低等毒性,国外关于其经呼吸道的毒性研究较多,而经口毒性研究颇少,仅个别国家提出了它在地面水中的卫生标准。本文系应生产和设计单位的要求,为制订DMF在地面水中的最高容许浓度提供科学依
Dimethylformamide (DMF) is a colorless liquid, structural formula: molecular weight: 73.09, boiling point: 153 ℃, soluble in water and organic solvents. It is a good solvent and has been widely used in industries such as fibers, coatings, polymer synthesis and motion picture film. Through the respiratory tract, gastrointestinal and intact skin invade the body, the main damage to the liver, is moderate to low toxicity, foreign research on its toxicity through the respiratory tract is relatively small, and few oral toxicity studies, only a few countries made it on the ground Health standards in water. This article is based on the requirements of the production and design units to provide a scientific basis for the development of the maximum allowable concentration of DMF in surface water
