Tlhahiso ea Phthalic Anhydride
Phthalic anhydride e hlahisoa haholo-holo ka oxidation ea o-xylene kapa naphthalene.Bongata ba tlhahiso ea anhydride ea phthalic e sebelisa oxidation ea o-xylene, e kenyelletsang ts'ebeliso ea li-catalyst le mocheso o phahameng.Mokhoa ona o hlahisa mocheso o mongata haholo 'me o ntša carbon dioxide e le sehlahisoa.Ka tlhokahalo e ntseng e hola ea phthalic anhydride, ho na le tlhoko e ntseng e eketseha ea ho nts'etsapele mekhoa e tsitsitseng ea tlhahiso ho fokotsa tšusumetso ea tikoloho.
Lisebelisoa tsa Phthalic Anhydride
Phthalic anhydride ke motsoako o feto-fetohang o sebelisoang liindastering tse fapaneng.E 'ngoe ea litšebeliso tsa eona tse ka sehloohong ke ho hlahisa li-plasticizers, tse kenngoa ka polasetiki ho ntlafatsa ho tenyetseha le ho tšoarella.Ho phaella moo, phthalic anhydride e sebelisoa ha ho etsoa dae le mebala, hammoho le ho hlahisa li-resine tsa polyester tse sa tsitsang.Mefuta e mengata ea likopo tsa phthalic anhydride e totobatsa bohlokoa ba eona lefapheng la tlhahiso mme e totobatsa tlhoko ea ts'ebeliso e tsitsitseng le e nang le boikarabelo ea motsoako ona.
Matšoenyeho a Tikoloho le Bophelo bo Botle
Leha e sebelisoa haholo, phthalic anhydride e hlahisitse matšoenyeho mabapi le phello ea eona ea tikoloho le bophelo bo botle.Tlhahiso le ts'ebeliso ea phthalic anhydride e ka lebisa ho lokolloeng ha litšila tse kotsi tsa moea, joalo ka li-volatile organic compounds (VOCs) le likhase tse futhumatsang lefatše.Ho feta moo, ho pepesehela phthalic anhydride nako e telele ho amana le ho hema le ho teneha ha letlalo, hammoho le litlamorao tse ka bang teng tsa ho ba le bana le nts'etsopele.Ho bohlokoa hore bankakarolo ba indasteri le balaoli ba sebetsane le mathata ana le ho kenya tšebetsong mehato ea ho fokotsa likotsi tsa tikoloho le bophelo bo botle tse amanang le phthalic anhydride.
Maikutlo a Bokamoso
Ha tlhoko ea phthalic anhydride e ntse e hola, ho na le tlhoko e matla ea ho lekola mekhoa e meng e tšoarellang le tsoelopele ea mahlale tlhahisong le ts'ebelisong ea eona.Boiteko ba ho nts'etsapele lits'ebetso tse tala le tse sebetsang hantle haholoanyane tsa tlhahiso, hammoho le lipatlisiso tsa mehloli e thehiloeng ho bioloji bakeng sa anhydride ea phthalic, li bohlokoa ho fokotsa phello ea tikoloho.Ho feta moo, ho amoheloa ha meralo e thata ea taolo le maemo a indasteri ho ka thusa ho netefatsa ts'ebetso e bolokehileng le ts'ebeliso ea phthalic anhydride.
Qetellong, tlhaiso-leseling ea morao-rao mabapi le phthalic anhydride e totobatsa bohlokoa ba eona liindastering tse fapaneng le tlhokeho ea ho rarolla mathata a eona a tikoloho le bophelo bo botle.Hoa hlokahala hore bankakarolo ba sebelisane molemong oa ho ntšetsa pele mekhoa le mahlale a tšoarellang ho fokotsa phello ea anhydride ea phthalic tikolohong le bophelo bo botle ba batho.Ka ho lula re na le tsebo le ho ba mahlahahlaha, re ka sebeletsa molemong oa ts'ebeliso e nang le boikarabelo le e tsitsitseng ea phthalic anhydride lilemong tse tlang.
