二氯甲烷是什么?我们该如何认识它呢?

二氯甲烷的用途非常广泛,因为二氯甲烷的溶解力强和毒性低的特点,它被广泛的应用于电影胶片,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?下面我们带着这一系列的问题跟着二氯甲烷厂家一起来了解一下。
Dichloromethane is widely used because of its strong solubility and low toxicity. It is widely used in film film, coating dissolving agent, gas smoke spray and other fields. So what do you know about dichloromethane? How to understand? What are its properties? Let's follow the manufacturers of dichloromethane with these 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、乙醚等,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炸的混合物。
Dichloromethane is commonly known as dichloride. The molecular formula is CH2Cl2, density is 1.326, boiling point is 39.8 ℃, dichloromethane is a non combustible low boiling point solvent, which is commonly used to replace flammable petroleum ether, ether, etc., and can be used as local anesthetics, refrigerants and fire extinguishing agents. Dichloromethane is a colorless, transparent, water specific liquid, volatile liquid, with the smell and sweetness similar to ether, which does not burn, but is mixed with high concentration oxygen to form an explosive mixture.
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、乙醚、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,然而当二氯甲烷与丙酮或甲醇液体以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 is miscible with most commonly used organic solvents, and can be mixed with other chlorine containing solvents, ether and ethanol in any proportion. Dichloromethane is difficult to dissolve in liquid ammonia at room temperature, and can be dissolved in phenol, aldehyde, ketone, glacial acetic acid, triethyl phosphate, formamide, cyclohexamine and ethyl acetoacetate. Pure dichloromethane has no flash point, and the solvent mixture containing equal volume dichloromethane and gasoline, solvent naphtha or toluene is non flammable. However, when dichloromethane is mixed with acetone or methanol liquid in 10:1 ratio, its mixing has flash point. After evaporation, it will form a flammable mixture with air.
二氯甲烷是甲烷氯化物中毒性比较小的,其毒性仅为四氯化碳毒性的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 a small toxic methane chloride, and its toxicity is only 0.11% of the toxicity of carbon tetrachloride. If dichloromethane is directly splashed into the eye, it has a pain and corrosive effect.
二氯甲烷的危害性也是很大的,它会对我们的环境和身体造成很大的危害,所以二氯甲烷厂家小编在此提醒大家,从事相关工作的人员一定要小心谨慎!
Dichloromethane is also very harmful, it will cause great harm to our environment and body, so the small compilation of dichloromethane manufacturers here reminds you that the personnel engaged in relevant work must be careful!
