2-(Trifluoromethoxy)benzoic acid（CAS# 1979-29-9) Introduction
He aniani kala ʻole ʻo TFMPA, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe e like me benzene a me ka ethanol. Loaʻa iā ia ka acidity ikaika a me ka oxidation, a pili i ka wai.
E hoʻohana:
Hoʻohana nui ʻia ʻo TFMPA ma ke ʻano he catalyst acid, he oxidant a he catalyst no ka esterification i ka synthesis organik. Hiki iā ia ke hoʻoikaika i ka holomua o ka hopena kemika a hoʻomaikaʻi i ka koho a me ka hopena o ka hopena.
Hanana:
Hoʻomaʻamaʻa pinepine ʻia ka hoʻomākaukau ʻana i ka TFMPA e ka hopena multi-step. Hoʻokahi ʻano hana maʻamau o ka hoʻomākaukau ʻana ma ka hana ʻana i ka trifluoromethane me ka chloromethylbenzene e hana ai i ka 2-chloromethyl-3-(trifluoromethoxy) benzene (CF3CH2OH) a me ka substrate pane. A laila, hoʻopili ʻia ka substrate hopena me kahi mea hoʻokahe e loaʻa iā TFMPA.
ʻIke palekana:
Pono ka hana palekana o TFMPA e hahai i nā lula palekana o ka hale hana. Ma muli o kona ʻakika a me ka oxidation, pono ia e pale i ka hoʻopili ʻana me nā mea flammable, nā mea hoʻoheheʻe organik a me nā kinoea puhi. Pono e ʻaʻahu ʻia nā lako pale pilikino e like me nā mīkina lima lab, nā maka aniani a me nā lole lab i ka wā o ka hana. I ka manawa like, pono e hana ʻia i loko o kahi wahi i hoʻoluʻu maikaʻi ʻia e pale i ka hōʻiliʻili ʻana o nā kinoea ʻino.
