Gamma-valerolactone e sebelisetsoa eng?
Y-valerolactone (GVL), motsoako o se nang mebala o qhibilihang ka metsing, o hohetse tlhokomelo e ngata lilemong tsa morao tjena ka lebaka la mefuta e mengata ea likopo. Ke cyclic ester, haholo-holo lactone, e nang le foromo C5H8O2. GVL e tsebahala habonolo ka monko le tatso ea eona e ikhethang.
GVL e sebelisoa haholo-holo e le solvent liindastering tse sa tšoaneng tse kenyeletsang meriana, litlolo, temo le petrochemicals. Thepa ea eona e ikhethang le chefo e tlaase e etsa hore e be khetho ea pele ea ho nkela metsoako ea setso e ka bang kotsi bophelong ba batho kapa tikolohong. Ho phaella moo, GVL e boetse e sebelisoa e le selelekela sa motsoako oa mefuta e sa tšoaneng ea metsoako ea bohlokoa.
E 'ngoe ea lisebelisoa tsa bohlokoa tsa GVL ke indastering ea meriana e le solvent e tsitsitseng le e sebetsang hantle. Lithethefatsi tse ngata le metsoako e sebetsang ea meriana (APIs) li entsoe le ho etsoa ka ho sebelisa metsoako ea tlhaho. Ka lebaka la thepa ea eona e ntle, GVL e fetohile mokhoa o ts'episang ho li-solvents tse sebelisoang hangata joalo ka dimethyl sulfoxide (DMSO) le N, N-dimethylformamide (DMF). E ka qhala mefuta e mengata ea lithethefatsi le li-API, e nolofatsa ho qaptjoa ha tsona le ho etsoa ha tsona ha e ntse e fokotsa likotsi tse ka 'nang tsa e-ba teng tse amanang le li-solvents tse ling.
Ka indasteri ea litlolo,GVLse sebedisoang joalo ka sehlapi se setala bakeng sa merero e fapaneng. Hangata e sebelisoa ho ntšitsoeng, ho hloekisa le ho kopanya metsoako ea litlolo. GVL e fana ka tharollo ea tikoloho ho feta lihlapolli tsa setso, tse atisang ho hlahisa lihlahisoa tse kotsi. Monko oa eona o bobebe le bokhoni bo fokolang ba ho teneha ha letlalo le tsona li etsa hore e be khetho e sireletsehileng ho litlolo tsa litlolo.
Temo ke karolo e 'ngoe ea kopo ea GVL. E sebelisoa e le mokelikeli lihlahisoa tse laolang likokoanyana, likokoana-hloko le li-fungicides. GVL e khona ho hlabolla le ho fana ka metsoako ena e sebetsang ho se phelang se lebeletsoeng ha e ntse e fokotsa litla-morao tse mpe. Ho phaella moo, khatello e tlaase ea mouoane le ntlha e phahameng ea ho belisa ea GVL e etsa hore e tšoanelehe bakeng sa ho etsoa le ho fana ka lik'hemik'hale tsa agrochemicals.
Ho feto-fetoha ha maemo ha GVL ho boetse ho fetela indastering ea petrochemical. E sebelisoa e le mokelikeli le mokelikeli o kopanetsoeng mekhoeng e mengata e fapaneng, ho kenyeletsoa ho ntšoa ha lik'hemik'hale tsa bohlokoa ho tsoa ho biomass le lihlahisoa tse tsoang ho petroleum.GVLe bontšitse bokhoni ba ho sebelisoa tlhahisong ea biofuel le lik'hemik'hale tse nchafalitsoeng, ho fana ka mekhoa e meng e tala le e tsitsitseng ho feta lihlahisoa tsa peterole.
Ntle le ho ba mokelikeli, GVL e ka sebelisoa e le ntho e qalang bakeng sa motsoako oa metsoako ea bohlokoa. E ka fetoloa lik'hemik'hale ho gamma-butyrolactone (GBL), motsoako o sebelisoang haholo ho hlahisa li-polymers, resin le meriana. Phetoho ea GVL ho GBL e kenyelletsa ts'ebetso e bonolo le e sebetsang, e etsang hore e be mokhethoa ea khahlehang bakeng sa lits'ebetso tsa indasteri.
Ka kakaretso, γ-valerolactone (GVL) ke motsoako oa lintho tse phelang tse nang le mefuta e mengata ea tšebeliso. Ka lebaka la chefo e tlase le ts'ebetso e ntle, ts'ebeliso ea eona e le mokelikeli indastering ea meriana, ea litlolo, ea temo le ea petrochemical e ntlafalitsoe haholo. GVL e fana ka mekhoa e meng e tšoarellang le e sebetsang ho feta lihlapolli tsa setso, e khothalletsang mekhoa e metle le e sireletsehileng. Ho feta moo, li-GVL li ka fetoloa lik'hemik'hale tsa bohlokoa, tse ntlafatsang ho feto-fetoha ha tsona le boleng ba moruo. Bokhoni le bohlokoa ba GVL bo lebelletsoe ho hola lilemong tse tlang ha liindasteri li ntse li tsoela pele ho batla tharollo e tšoarellang.
