Asiti ea Benzoic: Asiti ea Bohlokoa ea Organic le e Sireletsang
Masimo a Maholo a Kopo
Tšebeliso e ka sehloohong ea benzoic acid e kenyelletsa tšebeliso ea eona e le sesebelisoa sa ho boloka lintho tse phelang, se eketsang asiti, karolo ea monko o monate, le karolo e bohareng ea tlhahiso ea lintho tse phelang. Indastering ea lijo, benzoic acid ke sesebelisoa sa ho boloka lintho tse phelang se sebelisoang haholo se ka thibelang kholo ea likokoana-hloko ka katleho le ho lelefatsa bophelo ba lijo. Hangata e eketsoa lino, lisoso, jeme, lihlahisoa tse halikiloeng le lijong tse ling ho netefatsa polokeho le botsitso ba tsona. Mohlala, lino tse nang le khabone, benzoic acid e thibela kholo ea libaktheria le hlobo, e boloka boleng ba seno.
Indastering ea meriana, benzoic acid e sebelisoa ho hlahisa metsoako e mahareng bakeng sa meriana e itseng. E fana ka sehlopha se sebetsang sa carboxyl se ka nkang karolo liketsong tsa tlhaho tsa ho hlahisa lithibela-mafu, li-analgesic tse thibelang ho ruruha, le meriana e meng. Ho feta moo, benzoic acid e ka sebelisoa ho laola pH ea metsoako ea lithethefatsi, ho netefatsa botsitso ba tsona le ho fumaneha ha tsona. Mohlala, litlolong tse ling tsa lithibela-mafu tse ka ntle, benzoic acid e sebetsa e le mokhoa oa ho boloka mafura ho thibela hore a se ke a senyeha.
Indastering ea lik'hemik'hale, benzoic acid ke karolo ea bohlokoa ea motsoako oa lintho tse phelang. E ka sebelisoa ho kopanya li-ester tsa benzoic acid, tse kang benzyl benzoate, tse sebelisoang haholo indastering ea monko o monate le litlolo. Benzoic acid e ka boela ea etsoa ester ho hlahisa ethyl benzoate, e sebelisoang ho kopanyeng li-polymer le li-resin. Ho feta moo, benzoic acid e ka sebetsa e le acidifier ho kopanyeng lintho tse phelang, e laola pH ea sistimi ea karabelo ho khothaletsa liketso tse itseng.
Indastering ea litlolo, benzoic acid e sebelisoa ho laola pH ea litlolo, ho netefatsa botsitso le polokeho ea lihlahisoa. E ka boela ea sebetsa e le karolo ea monko o monate, e fa litlolo monko o ikhethang. Mohlala, liphatseng tse ling tsa monko o monate le lihlahisoa tsa tlhokomelo ea letlalo, benzoic acid e sebelisoa e le karolo ea ho boloka le monko o monate ho lelefatsa bophelo ba lihlahisoa le ho ntlafatsa monko oa tsona.
Asiti ea Benzoic ke k'hemik'hale e sireletsehileng haholo, empa mehato ea ho ela hloko e lokela ho nkuoa nakong ea tšebeliso le polokelo. E lokela ho bolokoa ka setshelong se koetsoeng ho qoba mongobo le tšilafalo. Lisebelisoa tse loketseng tsa tšireletso, tse kang liatlana le likhalase tsa mahlo, li lokela ho aparoa ha li tšoaroa ho thibela ho kopana le letlalo le mahlo.
