دی کلر و متان 106044 مرک
Dichloromethane 106044 Merck

دی‌کلرومتان (به انگلیسی: Dichloromethane) با فرمول شیمیایی CH_۲Cl_۲ یک ترکیب شیمیایی با شناسه پاب‌کم ۶۳۴۴ است.

نام دیگر آن متیلن کلراید است که جرم مولی آن 84.93 g/mol می‌باشد.

این ماده به‌طور طبیعی در میان جلبک‌ها و آتشفشان‌ها وجود دارد.

به‌طور مصنوعی هم در اثر واکنش کلرومتان یا متان با گاز کلر در دمای ۵۰۰-۴۰۰ درجه سلسیوس تولید می‌شود.

کاربرد آن اکثراً به عنوان حلال می‌باشد . این ماده در آب امتزاج ناپذیر است.

• در تولید قهوه و چای
• در تولید اسپری ها
• ضد عفونی کردن محصولات کشاورزی

Description
Catalogue Number	106044
Synonyms	DCM, Methylene chloride, Methylene dichloride
Description	Dichloromethane
Overview	With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" as well as "isocratic grade". This enables to minimize the gradient effect of the solvent involved.
