I-Phthalic Anhydride 99%, Ilungele Ukuthunyelwa ~

Isicelo:

Okokuqala, i-phthalic anhydride idlala indima ebalulekileyo kwicandelo lokwenziwa kwamayeza. Yinto ebalulekileyo ekwenziweni kwamayeza okulwa nokuvuvukala, amayeza okugaya ukutya, amayeza okubulala iintsholongwane, amayeza okulwa nomhlaza kunye namanye amayeza. Ukongeza, i-phthalic anhydride ikwayindlela yokulungiselela iihomoni ezahlukeneyo zezityalo ezifana ne-growth hormone kunye ne-auxin, nto leyo ebaluleke kakhulu ekukhuthazeni ukukhula kwezityalo kunye nokwandisa isivuno sezityalo.

Okwesibini, i-phthalic anhydride ikwasetyenziswa kakhulu kwishishini ledayi kunye neziqholo. Njengesixhobo esiphakathi sedayi kunye neziqholo, i-phthalic anhydride isetyenziselwa ukwenza iziqholo, imibala, iidayi zefayibha zokwenziwa, njl. Iimpawu zayo ezikhethekileyo zeekhemikhali zenza ukuba ingathathelwa indawo kwezi ndawo, yongeza imibala etyebileyo kunye neziqholo kubomi babantu.

Ukongeza, i-phthalic anhydride ikwadlala indima ebalulekileyo ekwenziweni kweeplastiki kunye nerabha. Yinto ebalulekileyo ekrwada ekwenziweni kweekhompawundi zepolymer ezifana ne-polyphenylene ether, i-polyamide, kunye ne-polyimide. Ezi khompawundi zepolymer zineempawu zomzimba ezintle kunye nozinzo lweekhemikhali, kwaye zisetyenziswa kakhulu kwiimoto, kwii-elektroniki, kulwakhiwo nakwezinye iindawo, zibonelela ngenkxaso enamandla kuphuhliso loluntu lwanamhlanje.

Kwicandelo lokwenziwa kwezinto eziphilayo, i-phthalic anhydride ineendlela ezahlukeneyo zokusetyenziswa. Ingasetyenziselwa i-carbonylation, i-propylene oxidation, ukulungiswa kwee-activated carbon esters, i-dry hydrogenation, i-aldehyde kunye ne-ketone esterification, i-nitric acid kunye ne-alkaline oxidation. Kwi-inorganic synthesis, i-phthalic anhydride ingasetyenziselwa ukwenza iityuwa ze-ammonium, kwaye ingasetyenziswa njenge-polymerization agent ephambili yokwenza i-copper zinc sulfide. Ezi mpendulo zokwenziwa zibonelela ngesiseko esityebileyo sezinto zophuhliso lweshishini leekhemikhali.

Ukongeza, i-phthalic anhydride ikwasetyenziswa kakhulu kwicandelo leekhemikhali ezintle. Ingasetyenziselwa iintlobo ngeentlobo ze-crystallization yokwahlulahlula kunye nee-catalytic reactions, kwaye ingasetyenziselwa nokulungiselela kunye netekhnoloji yokusasazwa kwee-polymers ezahlukeneyo ze-calcium sulfur ezingaphiliyo. Ekucutshungulweni kwemigodi, i-phthalic anhydride ingasetyenziselwa ukucutshungulwa kwezimbiwa zeediphozithi ze-ore ukuphucula ukusebenza kakuhle kwemigodi kunye nomgangatho we-ore. Ukongeza, i-phthalic anhydride ingasetyenziselwa njengezinto eziluhlaza kwii-insecticides kunye nee-pesticides, idlala indima ebalulekileyo ekuqinisekiseni ukukhula kwezityalo kunye nokwandisa isivuno.

Kwimveliso yemizi-mveliso, i-phthalic anhydride isetyenziswa kakhulu njengesinyibilikisi kunye nesithambisi. Ngenxa yokuba ibila kancinci kwaye inyibilika kakhulu, i-phthalic anhydride isetyenziswa kakhulu kumashishini okucoca ipetroli kunye neekhemikhali njengezinto eziqhekekayo. Kwangaxeshanye, ingasetyenziswa njengesixhobo sokuhlaziya i-chromatographic kunye nesithambisi seziqholo, njl.njl., inika indlela esebenzayo yohlalutyo lweekhemikhali kunye nokutsalwa kweziqholo.

Ukongeza, i-phthalic anhydride ingasetyenziselwa ukulungisa i-vanillin, ukumisela iswekile yomchamo, ukulungiselela iintlobo ngeentlobo ze-synergists kunye ne-antifreeze, njl. Ikwayenye yezinto ezisetyenziswayo zokwenza i-polyvinyl chloride stabilizers kwaye ilukhetho olufanelekileyo lonyango lomphezulu wesinyithi. Kwimveliso yerabha kunye neplastiki, i-phthalic anhydride ingasetyenziselwa njengesongezelelo serabha kunye nesongezelelo seplastiki ukuphucula ukusebenza kwemveliso kunye nomgangatho.
