Methanesulfonyl chloride/CAS：124-63-0

Methanesulfonyl chloride waa isku-dhis ka kooban kooxo shaqeynaya oo ah sulfonyl chloride, oo si caadi ah loogu isticmaalo isku-darka esters-ka methylsulfonic acid. Methyl sulfonyl chloride waa kiimiko aad u sun ah, hygroscopic, daxal leh, iyo jeexjeex leh. Isku-darkani wuxuu u baahan yahay in lagu kaydiyo meel qalalan, gaar ahaan qalajiyaha. Wax soo saarka warshadaha, wuxuu si toos ah u mari karaa falcelin xagjir ah oo xor ah oo u dhaxaysa methane iyo thionyl chloride.

Isticmaalka

Methanesulfonyl chloride waxaa loo isticmaali karaa falanqayn falanqayn ah; Waxa kale oo loo isticmaali karaa kicinta falgalka esterification iyo polymerization; Waxaa loo isticmaali karaa sidii walxo ceeriin ah oo loogu talagalay soo saarista methanesulfonic acid; Waxaa si weyn loogu isticmaali karaa sida walxo ceeriin ah oo macmal ah daawooyinka iyo sunta cayayaanka; Waxa kale oo loo isticmaali karaa sidii xasiliye dareere ah oo loo yaqaan 'sulfur dioxide', wakiil koloriin ah oo loogu talagalay rinjiyeynta anthraquinone iyo carbazole, wakiil qalajin degdeg ah oo loogu talagalay qalajinta khad saliid iyo dahaarka, hagaajiye rinjiyeynta polyester, nidaamiye midab leh oo loogu talagalay sawirrada midabka, wakiil isku-darka xylene, naphthalene iyo formaldehyde, iyo kaaliye rinjiyeyn dhogor.

Isticmaalka ugu weyn ee methylsulfonyl chloride waa in la diyaariyo methylsulfonyl esters laga bilaabo khamriga, taas oo u baahan ka qaybgalka saldhigyada aan ahayn nucleophilic inta lagu jiro habka falcelinta. Esters-ka Methyl sulfonate waxaa loo isticmaali karaa dhexdhexaad ahaan falcelinta beddelka nucleophilic, falcelinta ka saarista, falcelinta dhimista, iyo falcelinta dib-u-habaynta. Marka lagu daaweeyo Lewis acid iyo oxime, methanesulfonate wuxuu mari karaa dib-u-habaynta Beckmann.

Esters-ka aashitada methanesulfonic mararka qaarkood waxaa loo isticmaali karaa inay ilaaliyaan kooxaha khamriga, kuwaas oo ku xasilan xaaladaha aashitada oo laga yaabo inay ka difaacaan khamriga sodium mercuric acid.

Esters-ka aashitada methanesulfonic mararka qaarkood waxaa loo isticmaali karaa inay ilaaliyaan kooxaha khamriga, kuwaas oo ku xasilan xaaladaha aashitada oo laga yaabo inay ka difaacaan khamriga sodium mercuric acid.

Methyl sulfonyl chloride waxay la falgashaa amines si ay u sameeyaan methyl sulfonamide. Si ka duwan methylsulfonyl esters, methylsulfonylamide waa koox shaqaynaysa oo aad u deggan xaaladaha aashitada iyo alkaline labadaba. Haddii loo isticmaalo koox ilaalin ah si loo ilaaliyo kooxda amino, lithium aluminium tetrahydroxide ama falcelinta yaraynta birta ee milmi karta ayaa loo isticmaali karaa ka-hortagga.

Marka uu jiro koloriin naxaas ah, koloriin methylsulfonyl ayaa lagu dari karaa alkynes si loo sameeyo iskudhisyo β - chlorosulfonyl ah.
