關于到現在二氯甲烷的沸點是多少二氯甲烷的性質和用途這個話題，相信很多小伙伴都是非常有興趣了解的吧，因為這個話題也是近期非常火熱的。
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.
那么既然現在大家都想要知道二氯甲烷的沸點是多少二氯甲烷的性質和用途，小編也收集了相關的信息，那么下面分享給大家一起了解下吧。
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.
二氯甲烷的沸點
Boiling point of dichloromethane
二氯甲烷的沸點為39.8攝氏度，熔點為-97攝氏度，相對密度為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。如果二氯甲烷直接濺入眼中，有疼痛感并有腐蝕作用。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.
二氯甲烷的性質
Properties of dichloromethane
二氯甲烷，分子式CH2Cl2，一種有芳香氣味，比水重，易揮發的無色透明液體，是不可燃低沸點溶劑，常用來代替易燃的石油醚、乙醚等。世界衛生組織癌癥研究機構將它公布為致癌物。二氯甲烷還被列入有毒有害大氣污染物名錄和有毒有害水污染物名錄。
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.
