Ko te phthalic anhydride, e mōhiotia whānuitia ana ko te phthalic anhydride, he rauemi mata matū waro nui. He mea whānui hei ārai i te wera mō te rapa maori, te rapa isoprene, te rapa butadiene, te rapa styrene-butadiene, me te rapa nitrile, e ārai ana i te wera me te whakapai ake i te haumaru mahi. He iti noa te pānga ki te wā whakamomona me ngā āhuatanga tawhito o te hua kua oti. He tino whai hua mō ngā pūnaha Chemicalbook kei roto ngā whakatere thiazole-guanidine me te thiazole-thiuram, tae atu ki ngā matū me ngā whakatere kawakore, engari kāore i te pai mō ngā pūnaha whakamomona kore-thiuram. He ngāwari te marara, kāore e puāwai, ā, he iti te parahanga, engari ka puta pea he iti te tae o ngā matū rapa mā i te wā e pāngia ana e te mārama, ā, i te nuinga o te wā kāore i te pai mō te whakamahi me ngā matū rapa mā.

Ko te anhydride phthalic he anhydride hurihuri i hangaia mā te whakamaroke i te waikawa phthalic i roto i te ngota. Ka taea te whakahaere i te hydrolysis, te alcoholysis, me te ammonolysis, ā, ka tauhohe ki ngā warowaihā kakara hei hanga i ngā hua anthraquinone. I roto i te ahumahi, ka puta te anhydride phthalic mā te whakahāngai hau o te naphthalene ki te hau i te 350–360 °C i raro i te vanadium pentoxide catalysis, mā te whakahāngai rānei o te o-xylene ki te hau. Ka taea te whakamahi i te anhydride phthalic hei whakakapi mō te waikawa phthalic, ko te nuinga ka tauhohe ki ngā waipiro monohydric hei hanga i ngā esters, pērā i te dibutyl phthalate me te dioctyl phthalate.

Ngā āhuatanga matū: He tioata ma, he rite ki te ngira, he kakara paku. He ngawari. He wairewa noa iho i roto i te wai wera me te ether, he wairewa ki te acetone, te etanoru, te benzene, me te pyridine. Ka huri hei waikawa phthalic ina pā ki te wai kohua, ina pā roa rānei ki te wai. He pumau te penapena. Ka mura. He tūponotanga pahū te ranunga puehu-hau; te rohe iti o te mura (LCL) 12.6 g/cm³. He tūponotanga ahi te puehu kua whakatakotoria. Te pāmahana mura o te hauhautanga 160°C, te pāmahana mura-aunoa 545°C. He paitini; te rohe kukū e whakaaetia ana 1 mg/m³.

Ko te phthalic anhydride tētahi o ngā rauemi mata matū waro tino nui. Ko ōna pūtake matua ko te dibutyl phthalate, te dioctyl phthalate, me te diisobutyl phthalate, e whakamahia ana hei kirihou mō te PVC, me ētahi atu. Ka taea hoki te whakamahi i roto i te hanga kapia polyester kore-mākū, kapia alkyd, tae me ngā pigment, ngā momo peita, ngā tāpiringa kai, te phenolphthalein whakawairakau i roto i te rongoā, me ngā patupatu pēnei i te phosmet, metribuzin, me te sodium saccharin.
