Phthalic Anhydride 99%, Mākaukau no ka hoʻouna ʻana~

Noi:

ʻO ka mea mua, he kuleana koʻikoʻi ko ka phthalic anhydride i ke kahua o ka hana ʻana i nā lāʻau lapaʻau. He mea nui ia no ka hana ʻana i nā lāʻau anti-inflammatory, nā lāʻau gastrointestinal, nā antibiotics, nā lāʻau anticancer a me nā lāʻau lapaʻau ʻē aʻe. Eia kekahi, ʻo ka phthalic anhydride kekahi mea mua no ka hoʻomākaukau ʻana i nā hormones mea kanu like ʻole e like me 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 o nā mea kanu.

ʻO ka lua, hoʻohana nui ʻia ka phthalic anhydride i ka ʻoihana kala a me ka ʻala. Ma ke ʻano he waena no nā kala a me nā mea ʻala, hoʻohana ʻia ka phthalic anhydride e hana i nā mea ʻala, nā pigments, nā dyes fiber synthetic, a me nā mea ʻē aʻe. ʻO kona mau waiwai kemika kū hoʻokahi e hiki ai ke hoʻololi ʻia i kēia mau kahua, e hoʻohui ana i nā kala momona a me nā ʻala i ke ola o kānaka.

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

Ma ke kahua o ka synthesis organik, loaʻa i ka phthalic anhydride kahi ākea o nā noi. Hiki ke hoʻohana ʻia no ka carbonylation, propylene oxidation, hoʻomākaukau ʻana i nā esters kalapona i hoʻāla ʻia, hydrogenation maloʻo, aldehyde a me ketone esterification, nitric acid a me ka alkaline oxidation. I ka synthesis inorganic, hiki ke hoʻohana ʻia ka phthalic anhydride e synthesize i nā paʻakai ammonium, a hiki ke hoʻohana ʻia ma ke ʻano he mea polymerization nui no ka synthesis o ke keleawe zinc sulfide. Hāʻawi kēia mau hopena synthetic i kahi kumu waiwai no ka hoʻomohala ʻana i ka ʻoihana kemika.

Eia kekahi, he mau noi koʻikoʻi ko ka phthalic anhydride ma ke kahua o nā kemika maikaʻi. Hiki ke hoʻohana ʻia no nā ʻano crystallization hoʻokaʻawale like ʻole 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 like ʻole. I ka hana ʻana i ka mining, hiki ke hoʻohana ʻia ka phthalic anhydride no ka hana ʻana i nā minerala o nā waihona ore e hoʻomaikaʻi i ka pono o ka mining a me ka maikaʻi o ka ore. 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 koʻikoʻi 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 ma ke ʻano he mea hoʻoheheʻe a me ka mea unuhi. Ma muli o kona wahi paila 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 mea maka haki. I ka manawa like, hiki ke hoʻohana ʻia ma ke ʻano he reagent loiloi chromatographic a me kahi mea unuhi no nā mea ʻala, a pēlā aku, e hāʻawi ana i kahi ala kūpono no ka loiloi kemika a me ka unuhi ʻana i nā mea ʻala.

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