potassium-butoxide (KTB) CAS:865-47-4

Potassium t-butoxide (KTB) e sebelisoa haholo k'hemistring ea lintho tse phelang ka lebaka la thepa ea eona ea motheo e matla le tlhaho ea eona e seng ea nucleophilic. E 'ngoe ea tšebeliso ea eona ea mantlha ke ho tlosoa ha li-hydrogen tse nang le asiti ka har'a metsoako ea lintho tse phelang ho etsa litlamo tsa carbon-carbon le carbon-heteroatom. Tšobotsi ena e etsa hore e be ea bohlokoa liketsong tse kang aldol condensations, Claisen condensations, le litlatsetso tsa Michael. Ho feta moo, KTB e sebetsa e le motheo liketsong tsa ho felisa, e khothalletsa ho thehoa ha li-alkenes ho tsoa ho halides kapa alcohols. Ho feta moo, potassium t-butoxide e sebelisoa ho kopanyeng meriana, lik'hemik'hale tsa temo le lisebelisoa tse fapaneng tse sebetsang tsa lintho tse phelang. Sebopeho sa eona se seng sa nucleophilic se etsa hore e lokele liketso tse kenyeletsang lihlopha tse sebetsang tse bonolo tse ka angoang ke li-reagent tsa nucleophilic. KTB e boetse e thusa ho lokisoa ha li-ether, li-ester le lintho tse ling tse tsoang linthong tse phelang ka ho kenella ha eona ho Williamson ether synthesis le esterification reactions. Ntle le karolo ea eona k'hemistring ea maiketsetso, t-butoxide ea potassium e sebelisoa tlhahisong ea thepa ea polymer, haholo-holo e le catalyst kapa moqali oa tlhahiso ea polyolefin le li-polymer tse ling. Ho qhibiliha ha eona haholo lithakong tse fapaneng tsa tlhaho ho etsa hore e be reagent e sebetsang bakeng sa lits'ebetso tsena. Ho feta moo, KTB e ameha phetohong le ts'ebetsong ea libaka le lisebelisoa, haholo-holo lefapheng la mahlale a thepa. E sebelisoa ho hlahisa lihlopha tse itseng tse sebetsang holim'a libaka kapa li-substrate, e leng se nolofalletsang likamano tse etselitsoeng lits'ebetso tse fapaneng, joalo ka li-sensor, liphahlo le lisebelisoa tsa bongaka. Ka kakaretso, lits'ebetso tse feto-fetohang tsa potassium t-butoxide li e etsa reagent ea motheo tlhahisong ea lintho tse phelang, saense ea thepa le k'hemistri ea polymer. Motsoako oa eona o ikhethang oa boits'oaro bo matla ba motheo le bo seng ba nucleophilic bo lumella liphetoho tse fapaneng ha o ntse o fokotsa likarabo tse sa batleheng tse ka bang teng, e leng se etsang hore e be ea bohlokoa lipatlisisong tsa lik'hemik'hale tsa sejoale-joale le lits'ebetsong tsa indasteri.
