Phthalic Anhydride, dị njikere maka mbupu ~

Ngwa:

Nke mbụ, phthalic anhydride na-arụ ọrụ dị mkpa na ngalaba mmepụta ọgwụ. Ọ bụ isi akụrụngwa maka imepụta ọgwụ mgbochi mkpali, ọgwụ eriri afọ, ọgwụ nje, ọgwụ mgbochi ọrịa kansa na ọgwụ ndị ọzọ. Na mgbakwunye, phthalic anhydride bụkwa ihe mmalite maka nkwadebe nke homonụ osisi dị iche iche dị ka hormone na-eto eto na auxin, nke dị oke mkpa maka ịkwalite uto osisi na ịba ụba ihe ọkụkụ.

Nke abuo, a na-ejikwa phthalic anhydride n'ọtụtụ ebe na ụlọ ọrụ na-esiji esiji na isi ísì. Dị ka ihe etiti maka agba agba na ngwa nri, a na-eji phthalic anhydride eme ngwa nri, pigments, sịntetik fiber dyes, wdg. Njirimara kemịkalụ ya pụrụ iche na-eme ka ọ bụrụ nke a na-apụghị dochie anya n'ubi ndị a, na-agbakwunye agba agba na ihe na-esi ísì ụtọ na ndụ ndị mmadụ.

Na mgbakwunye, phthalic anhydride na-arụkwa ọrụ dị mkpa n'ịmepụta plastik na roba. Ọ bụ akụrụngwa dị mkpa maka imepụta ogige polymer dị ka polyphenylene ether, polyamide, na polyimide. Ogige ndị a polymer nwere ezigbo ihe anụ ahụ na nkwụsi ike nke kemịkalụ, a na-ejikwa ya na ụgbọ ala, ngwá electronic, ihe owuwu na mpaghara ndị ọzọ, na-enye nkwado siri ike maka mmepe nke ọha mmadụ nke oge a.

N'ihe gbasara njikọ organic, phthalic anhydride nwere ọtụtụ ngwa ngwa. Enwere ike iji ya maka carbonylation, propylene oxidation, nkwadebe nke carbon esters na-arụ ọrụ, hydrogenation akọrọ, aldehyde na ketone esterification, nitric acid na alkaline oxidation. Na njikọ nke inorganic, a pụrụ iji phthalic anhydride mee ka ammonium salts mee ihe, a pụkwara iji ya mee ihe dị ka isi ihe na-emepụta polymerization maka njikọ nke ọla kọpa zinc sulfide. Mmeghachi omume sịntetik ndị a na-enye ntọala ihe onwunwe bara ụba maka mmepe nke ụlọ ọrụ kemịkalụ.

Na mgbakwunye, phthalic anhydride nwekwara ngwa dị mkpa n'ọhịa nke ezigbo kemịkal. Enwere ike iji ya mee ihe dị iche iche nke crystallization nkewa na mmeghachi omume catalytic, a pụkwara iji ya maka nkwadebe na teknụzụ mgbasa ozi nke dị iche iche inorganic calcium sulfur polymers. Na nhazi Ngwuputa, enwere ike iji phthalic anhydride mee ihe maka nhazi ịnweta nke nkwụnye ego iji meziwanye arụmọrụ nke Ngwuputa na mma nke ọla. Tụkwasị na nke ahụ, a pụkwara iji phthalic anhydride mee ihe dị ka ihe eji eme ihe maka ụmụ ahụhụ na ọgwụ ndị na-egbu egbu, na-ekere òkè dị mkpa n'ịhụ na uto nke ihe ọkụkụ na-abawanye ụba.

Na mmepụta nke ụlọ ọrụ mmepụta ihe, phthalic anhydride na-ejikarị eme ihe dị ka ihe mgbaze na ihe na-emepụta ihe. N'ihi ebe esi mmiri dị ala yana nnukwu solubility, a na-eji phthalic anhydride eme ihe n'ọtụtụ ebe na nnụcha mmanụ na ụlọ ọrụ petrochemical dị ka akụrụngwa na-agbawa. N'otu oge ahụ, ọ nwekwara ike-eji dị ka chromatographic analysis reagent na extractant maka ngwa nri, wdg, na-enye ihe dị irè n'aka maka chemical analysis na ose mmịpụta.

Na mgbakwunye, phthalic anhydride nwekwara ike iji kwadebe vanillin, chọpụta shuga mmamịrị, kwadebe ụdị synergists dị iche iche na antifreeze, wdg Ọ bụkwa otu n'ime ihe eji eme polyvinyl chloride stabilizers na nhọrọ dị mma maka ọgwụgwọ elu igwe. N'ichepụta rọba na plastik, a pụrụ iji phthalic anhydride mee ihe dị ka ihe mgbakwunye rọba na ihe mgbakwunye plastik iji melite arụmọrụ ngwaahịa na ịdị mma.
