4-[2-(3 4-dimethylphenyl)-1 1 1 3 3 3-hexafluoropropan-2-yl]-1 2-dimethylbenzene（CAS# 65294-20-4)

Hoʻolauna

ʻO ka 2,2-bis (3,4-dimethylphenyl)hexafluoropropane he mea hoʻohui kino me ke ʻano kemika C20H18F6. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.

ʻAno:

ʻO ka 2,2-bis (3,4-dimethylphenyl)hexafluoropropane he wai waihoʻoluʻu a ʻeleʻele melemele me ke kaomi mahu haʻahaʻa. He 392.35g/mol kona kaumaha, he 1.20-1.21g/mL (20°C), a he 115-116°C.

E hoʻohana:

Hoʻohana nui ʻia ka 2,2-bis (3,4-dimethylphenyl) hexafluoropropane ma ke ʻano he stabilizer a me ka preservative no nā polymers. Hiki ke hoʻohui ʻia i nā huahana plastik a me ka ʻōpala e hoʻomaikaʻi i ko lākou pale ʻana a me ka pale wela. Eia kekahi, hiki ke hoʻohana ʻia i nā huahana uila e like me nā polymers thermoplastic, adhesives, coatings a me nā resins.

Hanana:

ʻO ka hoʻomākaukau ʻana o 2,2-bis (3,4-dimethylphenyl) hexafluoroppane e loaʻa pinepine ʻia e ka hopena fluorination o aniline. ʻO ka mua, hana ʻo Aniline me ka waika hydrofluoric e hana i ka fluoride aniline, a laila ma hope o ka hopena electrophilic substitution, hana ʻo aniline fluoride me ka trans-carbon tetrafluoride e hana i ka huahana i manaʻo ʻia.

ʻIke palekana:

ʻO 2,2-bis (3,4-dimethylphenyl) hexafluoropropane he haʻahaʻa haʻahaʻa ma lalo o nā hana ʻoihana maʻamau. Eia nō naʻe, ma ke ʻano he kemika, pono nō e hoʻolohe i ka hoʻohana palekana. Inā pili me ka ʻili a i ʻole nā ​​maka, holoi koke me ka wai nui. I ka wā o ka hoʻohana ʻana a i ʻole ka mālama ʻana, pono e mālama ʻia e pale i ke ahi a me nā mea hoʻoheheʻe a pale aku i ka hoʻopili ʻana me nā mea hoʻoheheʻe ikaika a me nā waikawa ikaika. ʻO ka hoʻohana ʻana i nā lako pale pilikino kūpono e like me nā mīkina lima pale, nā maka aniani a me nā lole pale e ʻōlelo ʻia i ka wā e lawelawe ai i kēia pūhui.
