二氯甲烷的用途非常廣泛，因為二氯甲烷的溶解力強和毒性低的特點，它被廣泛的應用于電影膠片，涂料的溶解劑，和氣煙霧噴射劑等領域，那么你知道二氯甲烷是什么?如何理解?它都有那些性質呢?下面我們帶著這一系列的問題跟著二氯甲烷廠家一起來了解一下。
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.
二氯甲烷俗稱二叉二氯，分子式是CH2Cl2，密度是1.326，沸點為39.8℃，二氯甲烷是不可燃低沸點溶劑，常用來代替易燃的石油醚、乙醚等，并可用作牙科局部麻醉劑、制冷劑和滅火劑等。二氯甲烷是無色、透明、比水重、易揮發的液體，有類似醚的氣味和甜味，不燃燒，但與高濃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，與絕大多數常用的有機溶劑互溶，與其他含氯溶劑、乙醚、乙醇也可以任意比例混溶。室溫下二氯甲烷難溶于液氨中，能很快溶解在酚、醛、酮、冰醋酸、磷酸三乙酯、甲酰胺、環己胺、乙酰乙酸乙酯中。純二氯甲烷無閃點，含等體積的二氯甲烷和汽油、溶劑石腦油或甲苯的溶劑混合物是不易燃的，然而當二氯甲烷與丙酮或甲醇液體以10：1比例混合時，其混合特具有閃點，蒸發后與空氣會形成易燃的混合物。
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較小的，其毒性僅為四氯化碳毒性的0.11%。如果二氯甲烷直接濺入眼中，有疼痛感并有腐蝕作用。
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，它會對我們的環境和身體造成很大的危害，所以二氯甲烷廠家小編在此提醒大家，從事相關工作的人員一定要小心謹慎!
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!
