Tetramethylammoniumchloride CAS:1112-67-0

Tetramethylammonium chloride (TMAC) e sebelisoa haholo tlhahisong ea lintho tse phelang e le catalyst ea phetisetso ea mohato, e nolofalletsang phetisetso e sebetsang ea li-ion lipakeng tsa mekhahlelo e fapaneng le ho khothaletsa liketso tse fapaneng tsa lik'hemik'hale. Motsoako ona o bohlokoa haholo lits'ebetsong tse kenyeletsang alkylation ea li-nucleophile le ho lokisoa ha metsoako ea ammonium ea quaternary, moo e nolofalletsang phetisetso ea li-alkylating agents pakeng tsa li-solvent tse sa tsoakoang, e leng se lebisang ho sekhahla se ntlafetseng sa karabelo le chai e ntlafetseng ea lihlahisoa. Ntle le karolo ea eona e le catalyst ea phetisetso ea mohato, tetramethylammonium chloride e sebelisoa tlhahisong ea tetramethylammonium hydroxide, e leng reagent ea bohlokoa k'hemistring ea lintho tse phelang. Tetramethylammonium hydroxide e sebelisoa hangata e le motheo o matla bakeng sa liketso tse fapaneng, ho kenyeletsoa le lits'ebetso tsa deprotonation le excretion, e leng se etsang hore TMAC e be selelekela sa bohlokoa tlhahisong ea k'hemik'hale ena ea bohlokoa. Ho feta moo, tetramethylammonium chloride e sebetsa e le mohloli oa li-cation tsa tetramethylammonium ka har'a li-ionic liquids, tse sebelisoang e le li-solvent tse sireletsang tikoloho lits'ebetsong tse fapaneng tsa lik'hemik'hale. Metsi ana a ionic a hapile tlhokomelo ka lebaka la thepa ea ona e ikhethang, joalo ka ho feto-fetoha ho tlase le botsitso bo phahameng ba mocheso, 'me TMAC e kenya letsoho tlhahisong le ts'ebelisong ea ona masimong a fapaneng ho kenyeletsoa le catalysis, electrochemistry, le saense ea thepa. Ho feta moo, TMAC e sebelisoa ho lokiseng li-resin tsa phapanyetsano ea ion, moo e sebetsang e le moemeli oa quaternizing ho fetola sebopeho le thepa ea matrix ea resin, e nolofalletsang mekhoa e sebetsang ea karohano le tlhoekiso liindastering tse fapaneng. Bokhoni ba eona ba ho hlahisa lihlopha tsa ammonium tsa quaternary mokokotlong oa resin bo ntlafatsa ts'ebetso le khetho ea lisebelisoa tsena lits'ebetsong tse kang kalafo ea metsi, tlhahiso ea meriana le tlhoekiso ea lik'hemik'hale. Ka bokhutšoanyane, tetramethylammonium chloride e bapala karolo ea bohlokoa ho tsoakoeng ha lintho tse phelang, catalysis, le lipatlisiso tsa lik'hemik'hale e le catalyst ea phetisetso ea mohato, e leng selelekela sa tetramethylammonium hydroxide, karolo ea li-ionic liquids, le moemeli oa quaternizing bakeng sa li-resin tsa phapanyetsano ea ion. Ts'ebeliso ea eona e feto-fetohang e kenya letsoho ho ntšetseng pele lits'ebetso tse fapaneng tsa lik'hemik'hale le nts'etsopele ea lisebelisoa tse ncha liindastering tse ngata.
