关于到现在二氯甲烷的沸点是多少二氯甲烷的性质和用途这个话题，相信很多小伙伴都是非常有兴趣了解的吧，因为这个话题也是近期非常火热的。
As for the boiling point of dichloromethane up to now, I believe many small partners are very interested in this topic, because this topic is also very hot recently.
那么既然现在大家都想要知道二氯甲烷的沸点是多少二氯甲烷的性质和用途，小编也收集了相关的信息，那么下面分享给大家一起了解下吧。
Now that we all want to know the boiling point of dichloromethane, the properties and uses of dichloromethane, Xiaobian has also collected relevant information, let's share it with you.
二氯甲烷的沸点
Boiling point of dichloromethane
二氯甲烷的沸点为39.8摄氏度，熔点为-97摄氏度，相对密度为1.33，微溶于水，溶于乙醇和乙醚。二氯甲烷是甲烷氯化物中毒性小的。如果二氯甲烷直接溅入眼中，有疼痛感并有腐蚀作用。二氯甲烷的蒸汽有麻醉作用。
The boiling point of dichloromethane is 39.8 ℃, melting point is - 97 ℃, relative density is 1.33, slightly soluble in water, soluble in ethanol and ether. Dichloromethane is less toxic than methane chloride. If dichloromethane is splashed directly into the eye, it will cause pain and corrode. The vapor of dichloromethane has an anesthetic effect.
二氯甲烷的性质
Properties of dichloromethane
二氯甲烷，分子式CH2Cl2，一种有芳香气味，比水重，易挥发的无色透明液体，是不可燃低沸点溶剂，常用来代替易燃的石油醚、乙醚等。世界卫生组织癌症研究机构将它公布为致癌物。二氯甲烷还被列入有毒有害大气污染物名录和有毒有害水污染物名录。
Dichloromethane, molecular formula CH2Cl2, is a colorless transparent liquid with aromatic odor, heavier than water, and easy to volatilize. It is a non combustible low boiling point solvent. It is often used to replace flammable petroleum ether, ether, etc. Who International Agency for research on cancer has declared it a carcinogen. Dichloromethane is also listed in the list of toxic and harmful air pollutants and toxic and harmful water pollutants.
