دی کلر و متان 106044 مرک Dichloromethane 106044 Merck دیکلرومتان(بهانگلیسی:Dichloromethane) بافرمول شیمیاییCH۲Cl۲یکترکیب شیمیاییباشناسه پابکم۶۳۴۴ است. نام دیگر آن متیلن کلراید است کهجرم مولیآن 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 عنوانحلالمیباشد . این ماده در آب امتزاج ناپذیر است. در تولید قهوه و چای در تولید اسپری ها ضد عفونی کردن محصولات کشاورزی Dichloromethane Synonyms:DCM, Methylene chloride, Methylene dichloride Hill Formula:CH₂Cl₂CAS #:75-09-2Chemical Formula:CH₂Cl₂Molar Mass:84.93g/molEC Number:200-838-9 Key Spec Table CAS # EC Number Hill Formula Chemical Formula Molar Mass 75-09-2 200-838-9 CH₂Cl₂ CH₂Cl₂ 84.93g/mol 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(r)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.
