I-anhydride ye-phthalic, eyaziwa ngokuba yi-phthalic anhydride, yinto ebalulekileyo ye-organic chemical raw material. Yinto esetyenziselwa ukulwa nokutshisa irabha yendalo, irabha ye-isoprene, irabha ye-butadiene, irabha ye-styrene-butadiene, kunye nerabha ye-nitrile, ithintela ukutsha kwaye iphucula ukhuseleko lokusebenza. Inempembelelo encinci kwixesha le-vulcanization kunye neempawu zokwaluphala kwemveliso egqityiweyo. Isebenza ngakumbi kwiinkqubo zeChemicalbook eziqulethe i-thiazole-guanidine kunye ne-thiazole-thiuram accelerators, kunye neekhompawundi ezine-alkaline accelerators, kodwa ayifanelekanga kwiinkqubo ze-vulcanization ezingenayo i-thiuram. Isasazeka lula, ayidubuli, kwaye inongcoliseko oluphantsi, kodwa iikhompawundi zerabha ezimhlophe zinokubonisa utshintsho oluncinci xa zichatshazelwa kukukhanya, kwaye ngokubanzi ayifanelekanga ukusetyenziswa neekhompawundi zerabha ezimhlophe.

I-anhydride ye-phthalic yi-anhydride ejikelezayo eyenziwe kukuphelelwa ngamanzi emzimbeni kwe-phthalic acid ngaphakathi kwimolekyuli. Ingadlula kwi-hydrolysis, i-alcoholysis, kunye ne-ammonolysis, kwaye iphendula kunye ne-aromatic hydrocarbons ukuze yenze i-anthraquinone derivatives. Kwimizi-mveliso, i-anhydride ye-phthalic iveliswa yi-gas-phase oxidation ye-naphthalene enomoya kwi-350–360 °C phantsi kwe-vanadium pentoxide catalysis, okanye nge-oxidation ye-o-xylene enomoya. I-anhydride ye-phthalic ingasetyenziswa endaweni ye-phthalic acid, ngokuyintloko iphendula kunye ne-monohydric alcohols ukwenza ii-esters, ezifana ne-dibutyl phthalate kunye ne-dioctyl phthalate.

Iimpawu zeekhemikhali: Iikristale ezimhlophe ezifana nenaliti ezinevumba elincinci. Ziyanyibilika. Zinyibilika kancinci emanzini ashushu nakwi-ether, zinyibilika kwi-acetone, i-ethanol, i-benzene, kunye ne-pyridine. Ziguquka zibe yi-phthalic acid xa zidibana namanzi abilayo okanye zidibana namanzi ixesha elide. Ukugcinwa kuhlala ixesha elide. Ziyatsha. Imixube yothuli nomoya ibangela ingozi yokuqhuma; umda ophantsi wokutsha (LCL) yi-12.6 g/cm³. Uthuli olufakwe kwindawo lubangela ingozi yomlilo. Ubushushu bokutsha kwe-aerosol yi-160°C, ubushushu bokutsha ngokuzenzekelayo yi-545°C. Ityhefu; umda woxinzelelo ovumelekileyo yi-1 mg/m³.

I-anhydride ye-phthalic yenye yezona zinto zibalulekileyo zekhemikhali yendalo. Izinto eziphambili eziphuma kuyo ziquka i-dibutyl phthalate, i-dioctyl phthalate, kunye ne-diisobutyl phthalate, ezisetyenziswa njengeeplastiki ze-PVC, njl. Ingasetyenziswa nakwimveliso yeeresini ze-polyester ezingagcwaliyo, iiresini ze-alkyd, iidayi kunye neepigment, iipeyinti ezahlukeneyo, izongezo zokutya, i-phenolphthalein yokulahla ityhefu kumayeza, kunye nezibulali zinambuzane ezifana ne-phosmet, i-metribuzin, kunye ne-sodium saccharin.
