Maleic anhydrideke motsoako oa lik'hemik'hale o feto-fetohang o hapileng tlhokomelo e kholo liindastering tse fapaneng ka lebaka la thepa ea eona e ikhethang le mefuta e mengata ea ts'ebeliso. Ho blog ena, re tla hlahloba tsebo ea morao-rao mabapi le anhydride ea maleic, ho kenyeletsoa ts'ebeliso ea eona, mekhoa ea tlhahiso, le tsoelopele ea morao-rao molemong oa ho kopanya le ts'ebeliso ea eona.
Maleic anhydride, e tsejoang hape e le cis-butenedioic anhydride, ke motsoako oa manyolo o nang le foromo ea lik'hemik'hale C4H2O3. Ke ntho e tšoeu, e tiileng, le e sebetsang haholo e sebelisoang haholo ha ho etsoa lik'hemik'hale tse fapaneng, li-polymer le li-resin. Maleic anhydride e hlahisoa ka oxidation ea benzene kapa butane, 'me ke ea bohlokoa lipakeng tsa motsoako oa asiti ea maleic, fumaric acid le lihlahisoa tse ling tse fapaneng tsa lik'hemik'hale.
E 'ngoe ea litšebeliso tsa bohlokoa tsa anhydride ea maleic ke selelekela sa tlhahiso ea li-polyester tse sa sebetseng, tse sebelisoang haholo ha ho etsoa lipolasetiki tse matlafalitsoeng ka fiberglass, likarolo tsa likoloi le liphahlo tsa leoatle. Maleic anhydride e boetse e sebelisoa ha ho etsoa lik'hemik'hale tse fapaneng tse ikhethang, joalo ka lik'hemik'hale tsa temo, li-detergents le li-additives tsa lubricant. Ho feta moo, anhydride ea maleic e sebelisoa ha ho etsoa lipolymer tse qhibilihang ka metsi, li-ajenti tsa boholo ba pampiri, hape e le ntho e kopanyang ho lokisa liraba tsa maiketsetso.
Lilemong tsa morao tjena, ho bile le tsoelo-pele e hlokomelehang tlhahisong ea maleic anhydride, ho tsepamisitsoe maikutlo ho ntlafatsa ts'ebetso ea eona le phello ea tikoloho. Boiteko ba lipatlisiso le nts'etsopele bo lebisitse ho nts'etsopele ea li-catalysts tse ncha le mahlale a karabelo a lumellang ts'ebetso e ntle le e bonolo ea tikoloho ea anhydride ea maleic. Ho feta moo, ho na le thahasello e ntseng e hola ea tšebeliso ea li-feedstocks tse nchafalitsoeng, joalo ka metsoako e entsoeng ka biomass, tlhahisong ea maleic anhydride, e le mokhoa oa ho fokotsa ho itšetleha ka lisebelisoa tsa mesaletsa ea khale le ho fokotsa tlhahiso ea khabone.
Karolo e 'ngoe ea lipatlisiso tse ntseng li tsoela pele ke ho lekola lits'ebetso tse ncha tsa anhydride ea maleic ho mahlale a ntseng a hlaha. Mohlala, anhydride ea maleic e bonts'itse ts'episo e le karolo ho nts'etsopele ea li-polymer tse ncha tse ka senyehang hape e le moaho oa ho kopanya lisebelisoa tse tsoetseng pele tse nang le thepa e ikhethang, joalo ka botsitso bo phahameng ba mocheso le ho hanyetsa lik'hemik'hale. Ho feta moo, ho na le thahasello e ntseng e eketseha tšebelisong ea maleic anhydride ha ho etsoa litlhare tse ncha le litsamaiso tsa phepelo ea lithethefatsi, ho nka monyetla ka lihlopha tsa eona tse sebetsang hape le tse sebetsang bakeng sa tokollo ea lithethefatsi e lebisitsoeng le ntlafatso ea bioavailability.
Qetellong, maleic anhydride e ntse e tsoela pele ho ba karolo ea bohlokoa indastering ea lik'hemik'hale, ka likopo tse fapaneng le liteko tse tsoelang pele tsa lipatlisiso tse reretsoeng ho ntlafatsa mekhoa ea eona ea tlhahiso le ho holisa ts'ebeliso ea eona makaleng a fapaneng. Ha tlhoko ea lisebelisoa tse tšoarellang le tse sebetsang hantle haholo e ntse e hola, anhydride ea maleic e ikemiselitse ho bapala karolo ea bohlokoa ho fihlela litlhoko tsena, e fana ka menyetla e mengata ea ntlafatso le tsoelopele lilemong tse tlang. Lula u le malala-a-laotsoe bakeng sa tsoelo-pele ea morao-rao lefatšeng ka anhydride ea maleic ha bafuputsi le litsebi tsa indasteri ba ntse ba tsoela pele ho hlahloba bokhoni ba eona.
