Phthalic Anhydride, Mākaukau No ka Hoʻouna ~

Noi:

ʻO ka mea mua, he hana koʻikoʻi ka phthalic anhydride i ke kahua o ka hana lāʻau. He kumu waiwai nui ia no ka hana ʻana i nā lāʻau anti-inflammatory, nā lāʻau ʻōpū, nā lāʻau antibiotic, nā lāʻau anticancer a me nā lāʻau ʻē aʻe. Eia kekahi, ʻo ka phthalic anhydride kekahi mea mua no ka hoʻomākaukau ʻana i nā hormones mea kanu like ʻole ka hormone ulu a me ka auxin, he mea nui ia no ka hoʻoulu ʻana i ka ulu ʻana o nā mea kanu a me ka hoʻonui ʻana i nā hua kanu.

ʻO ka lua, ua hoʻohana nui ʻia ka phthalic anhydride i ka ʻoihana kala a me ka ʻala. Ma ke ʻano he waena no nā mea ʻala a me nā mea ʻala, hoʻohana ʻia ka phthalic anhydride e hana i nā mea ʻala, nā puaʻa, nā mea hoʻonaninani fiber synthetic, a pēlā aku.

Eia kekahi, he hana koʻikoʻi ka phthalic anhydride i ka hana ʻana i nā plastics a me ka lāʻau. He mea waiwai nui ia no ka hana ʻana i nā pūhui polymer e like me polyphenylene ether, polyamide, a me polyimide. Loaʻa i kēia mau pūhui polymer nā waiwai kino maikaʻi loa a me ke kūpaʻa kemika, a hoʻohana nui ʻia i nā kaʻa, nā uila, ke kūkulu ʻana a me nā ʻano ʻē aʻe, e hāʻawi ana i ke kākoʻo ikaika no ka hoʻomohala ʻana i ke kaiāulu hou.

Ma ke kahua o ka organik synthesis, phthalic anhydride ka nui o nā noi. Hiki ke hoʻohana ʻia no ka carbonylation, propylene oxidation, ka hoʻomākaukau ʻana i nā esters carbon activated, hydrohydrogenation maloʻo, aldehyde a me ketone esterification, nitric acid a me ka alkaline oxidation. I ka inorganic synthesis, hiki ke hoʻohana ʻia ka phthalic anhydride e synthesize i nā paʻakai ammonium, a hiki ke hoʻohana ʻia e like me ke kumu polymerization nui no ka synthesis o ke keleawe zinc sulfide. Hāʻawi kēia mau hopena synthetic i kumu waiwai waiwai no ka hoʻomohala ʻana i ka ʻoihana kemika.

Eia kekahi, loaʻa i ka phthalic anhydride nā noi koʻikoʻi i ke kahua o nā kemika maikaʻi. Hiki ke hoʻohana ʻia no ka hoʻokaʻawale ʻana i ka crystallization a me nā hopena catalytic, a hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana a me ka ʻenehana hoʻopuehu o nā polymers calcium sulfur inorganic. I ka hana ʻana i ka mining, hiki ke hoʻohana ʻia ka phthalic anhydride no ka hoʻoheheʻe ʻana i nā minerala o nā waihona oka e hoʻomaikaʻi ai i ka maikaʻi o ka mining a me ka maikaʻi o ka ʻai. Eia kekahi, hiki ke hoʻohana ʻia ka phthalic anhydride ma ke ʻano he mea maka no nā insecticides a me nā pesticides, e pāʻani ana i kahi kuleana nui i ka hōʻoia ʻana i ka ulu ʻana o nā mea kanu a me ka hoʻonui ʻana i nā hua.

I ka hana ʻoihana, hoʻohana nui ʻia ka phthalic anhydride e like me ka solvent a me ka extractant. Ma muli o kona wahi hoʻolapalapa haʻahaʻa a me ka solubility kiʻekiʻe, hoʻohana nui ʻia ka phthalic anhydride i ka hoʻomaʻemaʻe ʻaila a me nā ʻoihana petrochemical ma ke ʻano he ʻōpala maka. I ka manawa like, hiki ke hoʻohana ʻia e like me ka reagent chromatographic analysis a me kahi extractant no nā mea ʻala, etc.

Eia kekahi, hiki ke hoʻohana ʻia ka phthalic anhydride no ka hoʻomākaukau ʻana i ka vanillin, hoʻoholo i ke kō mimi, hoʻomākaukau i nā ʻano synergists a me nā antifreeze, a me nā mea ʻē aʻe kekahi o nā mea maka no ka hana ʻana i nā stabilizers polyvinyl chloride a me kahi koho maikaʻi no ka mālama ʻana i ka metala. I ka hana ʻana a me ka plastic, hiki ke hoʻohana ʻia ka phthalic anhydride ma ke ʻano he mea hoʻohui a me ka plastic additive e hoʻomaikaʻi i ka hana huahana a me ka maikaʻi.
