I-Tosyl chloride CAS 98-59-9
I-Tosyl chloride (TsCl), njengomkhiqizo wamakhemikhali omuhle, isetshenziswa kabanzi embonini yodayi, yezemithi, kanye neyezibulala-zinambuzane. Embonini yodayi, isetshenziswa kakhulu ukukhiqiza izinto ezisetshenziswayo zodayi ohlakazekile, oqhwa, kanye nodayi we-asidi; embonini yezemithi, i-Chemicalbook isetshenziswa kakhulu ukukhiqiza ama-sulfonamides, i-mesulfonate, njll.; embonini yezibulala-zinambuzane, isetshenziswa kakhulu ekukhiqizeni i-mesotrione, i-sulfotrione, i-metalaxyl enhle, njll. Ngokuthuthuka okuqhubekayo kwezimboni zodayi, zezemithi kanye nezezibulala-zinambuzane, isidingo samazwe ngamazwe salo mkhiqizo sikhula usuku nosuku.
Kunezinqubo ezimbili eziyinhloko zendabuko ze-TsCl: 1. Ikhiqizwa yi-chlorination eqondile ye-toluene kanye ne-chlorosulfonic acid eningi kakhulu ekushiseni okuphansi. Le ndlela ikhiqiza i-o-toluenesulfonyl chloride enokuqukethwe okuphezulu, kanti i-p-toluenesulfonyl chloride ingumkhiqizo wayo ongezansi, futhi kokubili Kunzima ukuhlukanisa futhi kudla amandla amaningi; 2. I-Toluene kanye ne-chlorosulfonic acid zifakwa i-chlorosulfonic acid eningi kakhulu lapho kukhona usawoti othile kanye nasekushiseni okuthile. Nakuba le ndlela inesilinganiso somkhiqizo esiphezulu se-toluenesulfonyl chloride, isilinganiso sokuhlanza Indlela ilula futhi isebenzisa amandla aphansi. Kodwa-ke, ngenxa yokushisa okuphezulu kokusabela, uwoyela ohlukanisiwe we-sulfonated uqukethe ama-sulfone aphezulu futhi unenani eliphansi lokusetshenziswa. Isivuno sangempela singama-70% kuphela ku-Chemicalbook. Ngaphezu kwalokho, zombili izindlela zinokusetshenziswa okuphezulu kwe-chlorosulfonic acid yezinto zokusetshenziswa kanye ne-waste sulfuric acid ekhiqizwayo inciphile kakhulu, okungafanele ukusetshenziswa kwezimboni kanye nokwelashwa. Kukhona nemibiko yokuthuthukisa le ndlela. Okokuqala, i-p-toluenesulfonyl chloride engxubeni yokusabela iqiniswa ngokuphelele ngaphansi kwezimo ezithile futhi izinhlayiya zekristalu ziyakhuliswa. Indlela yokuhlunga ngqo ngaphandle kwe-hydrolysis isetshenziselwa ukususa i-p-toluenesulfonyl chloride engxubeni. Kodwa-ke, okwamanje kunezinkinga ezithile ekukhetheni imishini yezimboni futhi utshalomali lukhulu. Inqubo ethuthukisiwe: Kukhethwe ama-catalyst afanelekile kanye nezinye izimo zenqubo ezifanele.
I-Tosyl chloride (TsCl) iyikristalu emhlophe enamaqhubu enephuzu lokuncibilika elingu-69-71°C. Iyisidakamizwa esibalulekile sokwenziwa kwezinto eziphilayo futhi isetshenziswa kakhulu ekwakhiweni kwe-chloramphenicol, i-chloramphenicol-T, i-thiamphenicol kanye neminye imithi.
