二氯甲烷是氣體還是液體?

二氯甲烷是氣體還是液體?二氯甲烷它不是氣體的,而是一種液體,是一種無色、具有刺激性香味的液體。氫氧化鉀廠家提醒您,二氯甲烷它的特點是透明不燃性低沸點溶劑,易容易揮發。
Is methylene chloride a gas or a liquid? Dichloromethane is not a gas, but a liquid, which is colorless and has a pungent smell. The potassium hydroxide manufacturer reminds you that dichloromethane is a transparent, incombustible, low boiling solvent that is easy to volatilize.
因二氯甲烷的溶解力強,不燃燒,毒性低,所以它可以微溶于水、乙醚、乙醇、醚、氯仿、苯、二硫化碳等有機溶劑混溶,能溶解生物堿,油脂,橡膠,樹脂,纖維素酯等。
Because of its strong solubility, non combustion and low toxicity, dichloromethane can be slightly soluble in water, ether, ethanol, ether, chloroform, benzene, carbon disulfide and other organic solvents, and can dissolve alkaloids, oils, rubber, resins, cellulose esters, etc.
二氯甲烷的性質:
Nature of dichloromethane:
二氯甲烷分子式為CH2Cl2,分子量84.93。無色透明液體,具有類似醚的刺激性氣味。微溶于水,溶于乙醇和乙醚。是不可燃低沸點溶劑,常用來代替易燃的石油醚、乙醚等。
The molecular formula of dichloromethane is CH2Cl2, and the molecular weight is 84.93. Colorless transparent liquid with irritating odor similar to ether. Slightly soluble in water, soluble in ethanol and ether. It is a nonflammable low boiling point solvent, often used to replace flammable petroleum ether, ether, etc.

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。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。
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. Dichloromethane is slightly soluble in water and mutually soluble with most commonly used organic solvents. It can also be miscible with other chlorinated solvents, ether and ethanol in any proportion.
二氯甲烷能很快溶解在酚、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,其混合液具有閃點,蒸氣與空氣形成爆炸性混合物,爆炸極限6.2%~15.0%(體積)。
Dichloromethane can be quickly dissolved in phenol, aldehyde, ketone, glacial acetic acid, triethyl phosphate, formamide, cyclohexylamine and ethyl acetoacetate. Pure dichloromethane has no flash point, and the solvent mixture containing equal volume of dichloromethane and gasoline, solvent naphtha or toluene is not flammable. However, when dichloromethane is mixed with acetone or methanol liquid at a ratio of 10:1, the mixture has a flash point, and vapor and air form an explosive mixture, with an explosion limit of 6.2%~15.0% (volume).
二氯甲烷在工業生產中的適用范圍非常廣泛,很多溶劑和發泡劑中都可以見到二氯甲烷的身影,比如:涂料溶劑、金屬清洗劑等。二氯甲烷還是生產霉素類藥品的重要原材料,在醫藥制造行業占有一席之地。更多相關內容就來我們網站http://www.xxxlicious.com進行咨詢!
Dichloromethane is widely used in industrial production. Dichloromethane can be found in many solvents and foaming agents, such as paint solvent, metal cleaner, etc. Dichloromethane is also an important raw material for the production of mycomycin drugs, and has a place in the pharmaceutical manufacturing industry.
