Mmaraka oa lefats'e oaphthalic anhydridee lebelletsoe ho paka kholo e kholo lilemong tse tlang, ho latela litaba tsa morao-rao tsa 'maraka tsa selemo le selemo tsa 2024. Phthalic anhydride ke karolo ea bohlokoa ea lik'hemik'hale e sebelisoang tlhahisong ea lihlahisoa tse fapaneng, ho kenyeletsoa li-plasticizers, resin le dae.Tlhokahalo e ntseng e eketseha ea lihlahisoa tsena tse sebelisoang qetellong ho liindasteri tse kang likoloi, kaho le thepa ea bareki e tsamaisa kholo ea 'maraka oa phthalic anhydride.
E 'ngoe ea litloaelo tsa bohlokoa tse bopang mmaraka ke tlhokahalo e ntseng e eketseha ea li-plasticizer tse se nang phthalate.Ka tlhokomeliso e ntseng e hola mabapi le likotsi tse ka bang teng tsa bophelo bo botle le tikoloho tse amanang le li-phthalates, ho na le phetoho e lebisang tšebelisong ea li-plasticizer tse tsoang mehloling e thehiloeng ho bio kapa e seng ea phthalate.Mokhoa ona o lebelletsoe ho ama matla a 'maraka le ho tsamaisa nts'etsopele ea lihlahisoa tse ncha le lihlahisoa lilemong tse tlang.
Ntho e 'ngoe ea bohlokoa e susumetsang 'maraka ke ho tsepamisa maikutlo ho ntseng ho eketseha ho mekhoa e tsitsitseng ea tlhahiso.Baetsi ba tsetela ho mahlale a fokotsang tšusumetso ea tikoloho ea tlhahiso ea phthalic anhydride, joalo ka ho amoheloa ha mekhoa ea catalytic oxidation le ts'ebeliso ea li-feedstocks tse nchafalitsoeng.Maiteko ana a lebelletsoe ho tsamaisa 'maraka ho fihlela litharollo tse tšoarellang le tse bonolo haholoanyane tsa tikoloho, tse tsamaellanang le ts'ebetso ea lefats'e ea tlhahiso ea lik'hemik'hale tse tala.
Mabapi le matla a tikoloho, Asia-Pacific ho lebelletsoe hore e tla lula e le 'maraka o ka sehloohong oa phthalic anhydride, e susumetsoang ke kholo ea liindasteri le kholo ea litoropo linaheng tse kang China le India.Lefapha le matla la tlhahiso ea tikoloho le bareki ba ntseng ba eketseha ba ntse ba matlafatsa tlhokahalo ea phthalic anhydride lits'ebetsong tse fapaneng.
Ha re shebile pele, 'maraka oa phthalic anhydride o se o le malala a laotsoe bakeng sa kholo e tsitsitseng, e tšehelitsoeng ke tsoelopele e tsoelang pele ea mahlale a morao-rao, maemo a taolo a fetohang, le likhetho tse fetohang tsa bareki.Leha ho le joalo, liqholotso tse kang litheko tse sa fetoheng tsa thepa e tala le lithibelo tsa taolo ho li-phthalates libakeng tse ling li ka ama kholo ea mmaraka ho isa bohōleng bo itseng.
Qetellong, 'maraka oa phthalic anhydride o hlophiselitsoe ho paka tsoelo-pele le menyetla e hlokomelehang lilemong tse tlang, e susumetsoang ke mekhoa e tsoelang pele ea indasteri le ho lelekisa tharollo ea moshoelella le e ncha.Bankakarolo ho phatlalla le ketane ya boleng, ho tloha ho bahlahisi ho isa ho basebedisi ba ho qetela, ba tla hloka ho ikamahanya le diphetoho tsena le ho rua molemo ka menyetla e hlahang mmarakeng.
