Acetic Acid Bakeng sa Tšebeliso ea Liindasteri

Acetic acid, eo hape e tsejoang e le asiti ea acetic, ke motsoako o sebetsang oa lintho tse ngata o sebelisoang liindastering tse fapaneng. E na le foromo ea lik'hemik'hale CH3COOH 'me ke organic monobasic acid eo e leng motsoako oa bohlokoa ka har'a asene. Mokelikeli ona o se nang ’mala o fetoha sebōpeho sa kristale ha o tiea ’me o nkoa e le ntho e nang le asiti hanyenyane le e senyang haholo. E tlameha ho sebetsoa ka hloko ka lebaka la bokhoni ba eona ba ho hlohlona ha mahlo le nko.

Tšebeliso

E 'ngoe ea litšebeliso tsa mantlha tsa asiti ea acetic ke tlhahiso ea acetic anhydride, acetate esters, le cellulose acetate. Li-derivatives tsena li sebelisoa haholo indastering ea ho roala le ho thusa ho nts'etsopele ea boleng bo phahameng, bo tšoarellang. Acetic anhydride ke motsoako oa bohlokoa tlhahisong ea li-preservatives tsa patsi, athe cellulose acetate e sebelisoa ha ho etsoa lipente, li-primers le li-varnish. Ka ho amohela lihlahisoa tse thehiloeng ho acetate, liindasteri li ka ntlafatsa katleho, nako e telele le boipiletso bo akaretsang ba likopo tsa bona tsa ho roala.

Ho feta moo, asiti ea acetic e sebelisoa haholo tlhahisong ea li-acetate. Acetate e na le mefuta e mengata ea likopo tse kenyelletsang tšebeliso e le solvent ha ho etsoa lik'hemik'hale tse fapaneng, haholo indastering ea meriana le e ntle ea lik'hemik'hale. Ho phaella moo, e ka sebelisoa e le lisebelisoa tse tala ha ho etsoa li-adhesives, li-coatings le li-plastiki. Lihlahisoa tsa acetate li tsejoa ka bohloeki ba tsona bo phahameng, botsitso le ho feto-fetoha ha maemo, ho etsa hore e be khetho e babatsehang bakeng sa litlhoko tse fapaneng tsa indasteri.

Ntle le lits'ebetso tsena, asiti ea acetic ke motsoako oa bohlokoa ho li-analytical reagents, organic synthesis, le motsoako oa li-pigments le meriana. Litšobotsi tsa eona li e nolofalletsa ho tsamaisa mekhoa e fapaneng ea lik'hemik'hale le mekhoa ea maiketsetso. E thusa ho hlahisa li-pigments tse sebelisoang lipente, li-inks le lidae, ho li fa mebala e khanyang le e tšoarellang nako e telele. Ho feta moo, asiti ea acetic e sebelisoa ho kopantseng lithethefatsi 'me e bapala karolo ea bohlokoa ho nts'etsopele ea lithethefatsi tse ntlafatsang bophelo ba batho lefatšeng ka bophara.

Qetellong, asiti ea acetic ke motsoako oa bohlokoa oa manyolo o nang le sebaka liindastering tse ngata. Lisebelisoa tsa eona li tsoa ho tlhahiso ea acetic anhydride, acetates le cellulose acetates bakeng sa indasteri ea pente ho ea ho li-analytical reagents, organic synthesis le synthesis ea li-pigments le meriana. Ka thepa le mesebetsi ea eona e fapaneng, asiti ea acetic e bonahala e le motsoako oa bohlokoa bakeng sa likhoebo tse batlang ho ntlafatsa lihlahisoa le lits'ebetso tsa tsona. Leha ho le joalo, ho bohlokoa ho sebetsana le asiti ea acetic ka hloko hobane e ea senya ebile e ka teneha.
