二氯甲烷的用途非常普遍，因为二氯甲烷的溶解力强和毒性低的特点，它被普遍的应用于电影胶片，涂料的溶解剂，和气烟雾喷射剂等领域，那么你知道二氯甲烷是什么？如何理解？它都有那些性质呢？下面氢氧化钾厂家和您带着这一系列的问题来了解一下。

The use of dichloromethane is very common. Because of its strong solubility and low toxicity, it is widely used in film, paint dissolvers, and aerosol sprays. Do you know what dichloromethane is? How to understand? What are its properties? The potassium hydroxide manufacturer and you will take this series of questions to understand.

二氯甲烷俗称二叉二氯，分子式是CH2Cl2，密度是1.326，沸点为39.8℃，二氯甲烷是不可燃低沸点溶剂，常用来代替易燃的石油醚等，并可用作牙科局部麻醉剂、制冷剂和灭火剂等。二氯甲烷是无色、透明、比水重、易挥发的液体，有类似醚的气味和甜味，不燃烧，但与高浓度氧混合后形成爆的混合物。

Dichloromethane is commonly known as binary dichloride. Its molecular formula is CH2Cl2, density is 1.326, and boiling point is 39.8 ℃. Dichloromethane is a nonflammable low boiling point solvent, which is often used to replace flammable petroleum ether, and can be used as dental local anesthetic, refrigerant, fire extinguishing agent, etc. Dichloromethane is a colorless, transparent liquid, heavier than water, and volatile. It has an ether like smell and sweet taste, does not burn, but forms an explosive mixture when mixed with high concentration oxygen.

二氯甲烷微溶于水，与绝大多数常用的有机溶剂互溶，与其他含氯溶剂、乙醇也可以任意比例混溶。室温下二氯甲烷难溶于液氨中，能很快溶解在酚、醛、酮、冰醋酸、磷酸三乙酯、甲酰胺、环己胺、乙酰乙酸乙酯中。纯二氯甲烷无闪点，含等体积的二氯甲烷和汽油、溶剂石脑油或甲苯的溶剂混合物是不易燃的，然而当二氯甲烷与甲醇液体以10：1比例混合时，其混合特具有闪点，蒸发后与空气会形成易燃的混合物。

Dichloromethane is slightly soluble in water and mutually soluble with most commonly used organic solvents. It can also be miscible with other chlorine containing solvents and ethanol in any proportion. Dichloromethane is difficult to dissolve in liquid ammonia at room temperature, but can quickly dissolve in phenol, aldehyde, ketone, glacial acetic acid, triethyl phosphate, formamide, cyclohexylamine, and ethyl acetoacetate. Pure dichloromethane has no flash point. The solvent mixture containing equal volume of dichloromethane and gasoline, solvent naphtha or toluene is not flammable. However, when dichloromethane is mixed with methanol liquid at a ratio of 10:1, its mixing has a flash point, and it will form a flammable mixture with air after evaporation.

二氯甲烷可以用于脱漆剂，在用于透明塑料的水泥中用作溶剂，通常与其他溶剂混合以帮助溶解接触粘合剂中使用的树脂；用作咖啡、香料和啤酒花脱咖啡因的萃取溶剂；纺织工业中的载体溶剂；用作溶剂。

Dichloromethane can be used as a paint remover, as a solvent in cement used for transparent plastics, and is usually mixed with other solvents to help dissolve the resin used in contact adhesives; Used as the extraction solvent for decaffeinating coffee, spices and hops; Carrier solvent in textile industry; Used as solvent.

二氯甲烷是甲烷氯化物中毒性比较小的，其毒性为四氯化碳毒性的0.11%。如果二氯甲烷直接溅入眼中，有疼痛感并有腐蚀作用。

Dichloromethane is less toxic than methane chloride, and its toxicity is 0.11% of that of carbon tetrachloride. If dichloromethane is directly splashed into the eyes, it will cause pain and corrosion.
