Dichloromethane (DCM, methylene chloride, or methylene bichloride) is an organochlorine compound with the formula C H 2 Cl 2. This colorless, volatile liquid with a chloroform -like, sweet odor is widely used as a solvent. Although it is not miscible with water, it is slightly polar, and miscible with many organic solvents. [12]

Methylene chloride is a colorless liquid with a mild, sweet odor. Another name for it is dichloromethane. Methylene chloride does not occur naturally in the environment.Methylene chloride is used as an industrial solvent and as a paint stripper.

二氯甲烷具有廣譜的溶解力、低沸點以及相對而言最低的毒性和相對而言最好的反應惰性，使其成為有機合成中使用頻率位居第一的有機溶劑。 作為溶劑其地位幾乎跟無機鹽化學中的水相當 [3]。 二氯甲烷因為 立體電子效應 而顯惰性，通常不參與化學反應。 但在一定條件下也可以參與反應。 工業上曾經發生過殘留二氯甲烷與 疊氮化鈉 在 N,N-二甲基甲醯胺 里發生反應，生成 二疊氮甲烷 導致工廠爆炸的事故 [3]。 將生咖啡豆以高壓水蒸氣處理後，調整含水量，再浸泡於二氯甲烷 …

2021年6月2日 · 【二氯甲烷 (methylene chloride), CAS # 75-09-2】，二氯甲烷的的暴露多源自於吸入含有二氯甲烷的空氣，但仍有可能因為皮膚的接觸或喝下含有二氯甲烷的水而受到暴露。 吸入大量的二氯甲烷會損害中樞神經系統，若接觸到眼睛或皮膚則會導致灼傷。 一、什麼是二氯甲烷 (methylene chloride)？ 二氯甲烷是一種帶有淡淡甜味的無色液體，且它在環境中並不會自然產生。 二氯甲烷的另一個英文名稱是dichloromethane。 二氯甲烷被用來當作工業用溶劑或者是油漆 …

The product is a 10%v/v solution of dichloromethane in methanol. Dichloromethane (DCM) is a chlorinated organic solvent that has C2V symmetry, low boiling point, high density and is immiscible in water. A study reports the dielectric characteristics of DCM over a …

DICHLOROMETHANE reacts vigorously with active metals such as lithium, sodium and potassium, and with strong bases such as potassium tert-butoxide. It is incompatible with strong oxidizers, strong caustics and chemically active metals such as aluminum or magnesium powders. The liquid will attack some forms of plastic, rubber and coatings.
