Phthalic anhydride 99%, ulungele ukuthunyelwa ~

Isicelo:

Okokuqala, i-phthalic anhydride idlala indima ebalulekile emkhakheni wokukhiqiza izidakamizwa. Kuyinto ebalulekile ebonakalayo yokwenziwa kwezidakamizwa ezilwa nokuvuvukala, izidakamizwa zesisu, ama-antibiotic, izidakamizwa zezi-anticancer nezinye izidakamizwa. Ngaphezu kwalokho, i-phthalic anhydride ibuye ibe yisandu sokulungiswa kwama-hormone okutshala ahlukahlukene njengokukhula kwama-hormone kanye ne-auxin, okubaluleke kakhulu ekuthuthukiseni ukukhula kwezitshalo kanye nokwanda kwezitshalo.

Okwesibili, i-phthalic anhydride nayo isetshenziswa kabanzi kudayi kanye nekhambo lamakha. Njengomphakathi we-Dyses kanye nezinongo, i-phthalic anhydride isetshenziselwa ukwenza izinongo, imibala, izakhiwo zayo zokwenziwa zamakhemikhali ziyenza ingafinyeleleki kule mikhakha, engeza izici ezicebile ezimpilweni zabantu.

Ngaphezu kwalokho, i-anhydride ye-phthalic nayo idlala indima ebalulekile ekwakheni amapulasitiki nerabha. Kuyinto ebalulekile eluhlaza ebonakalayo yokwenziwa kwamakhompiyutha e-polymer anjenge-polyphenene ether, i-polyamide, ne-polymide. Lawa makhompiyutha e-polymer anezinto ezinhle kakhulu zomzimba kanye nokuqina kwamakhemikhali, futhi asetshenziswa kabanzi ezimotweni, e-elektroniki, ekwakheni nakwezinye izinkambu, anikeze ukwesekwa okuqinile ekuthuthukiseni umphakathi wanamuhla.

Ensimini yokuhlanganiswa kwe-organic, i-phthalic anhydride inezinhlobonhlobo zezicelo. Ingasetshenziselwa i-carbonylation, i-propelene oxidation, ukulungiswa kwe-activated carbon ecrers, i-hydrogenation eyomile, i-aldehyde ne-ketone yokuchazwa, i-nitric acid kanye ne-oxidation ye-alkali. Ngokuvumelanisa kwe-inorganic, i-anhydride ye-phthalic ingasetshenziswa ukuhlanganisa usawoti we-ammonium, futhi futhi ingasetshenziswa njenge-ejenti enkulu ye-polymerization yokuhlanganiswa kweCopper Ninc Sulfide. Lokhu kusabela okwenziwe kunikeza isisekelo sezinto ezibonakalayo zokuthuthuka kwemboni yamakhemikhali.

Ngaphezu kwalokho, i-phthalic anhydride nayo inezicelo ezibalulekile emkhakheni wamakhemikhali amahle. Ingasetshenziselwa ukuhlukaniswa okuhlukahlukene okuhlukanisayo kanye nokusabela kwe-catalytic, futhi nakho kungasetshenziselwa ubuchwepheshe kanye nobuchwepheshe bokuhlakazeka kwama-polfure ahlukahlukene we-inOrganic calcium sulfor. Ekucutshungulweni kwezimayini, i-anhydride ye-phthalic ingasetshenziselwa ukucubungula amaminerali amadiphozithi ka-Ore ukuthuthukisa ukusebenza kahle kwezimayini nekhwalithi ye-ore. Ngaphezu kwalokho, i-phthalic anhydride nayo ingahle isetshenziswe njengento eluhlaza ye-insecticides kanye nezibulala-zinambuzane, idlala indima ebalulekile ekuqinisekiseni ukukhula kwezilimo kanye nezithelo ezandayo.

Ekukhiqizweni kwezimboni, i-anhydride ye-phthalic isetshenziswa ikakhulukazi njenge-solvent kanye nokukhipha. Ngenxa yephuzu layo elibilayo elisezingeni eliphansi ne-solubility ephezulu, i-phthalic anhydride isetshenziswa kabanzi ekucongeni kukaphethiloli kanye nezimboni ze-petrochemical njengezinto eziphikisayo eziqhekekile. Ngasikhathi sinye, futhi ingasetshenziswa njenge-Chromatographic ehlaziya i-realent kanye ne-extracting yezinongo, njll., Ukunikeza izindlela ezisebenzayo zokuhlaziywa kwamakhemikhali kanye nokukhishwa kwezinongo.

Ngaphezu kwalokho, i-phthalic anhydride nayo ingasetshenziswa ukulungiselela i-vanillin, inqume ushukela womchamo, lungiselela ahlukahlukene ama-synergists kanye no-antifreeze, futhi kungenye yezinto zokwenziwa kwe-polyviny chloride kanye nokwelashwa okuhle kwensimbi. E-Rubber ne-Plastic Anhydride, i-phthalic anhydride ingasetshenziswa njengesengezo senjoloba nepulasitiki sokwengeza ukusebenza komkhiqizo kanye nekhwalithi.
