Hoʻolauna
1-Bromo-3,3,3-trifluoroacetone. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o kēia pūhui:
ʻAno maikaʻi:
ʻO 1-Bromo-3,3,3-trifluoroacetone he wai kala ʻole me kahi ʻala ʻala kūikawā ma ka lumi wela a me ke kaomi. Hiki ke hoʻoheheʻe ʻia i loko o nā waiʻona, eter, a me kekahi mau mea hoʻoheheʻe organik, a hiki ʻole ke hoʻoheheʻe ʻia i ka wai. He kiʻekiʻe ke kaomi mahu a me ka volatility ka hui.
E hoʻohana:
ʻO 1-Bromo-3,3,3-trifluoroacetone ka nui o nā noi i ka ʻoihana kemika. ʻO kekahi o ka hoʻohana nui ʻana ma ke ʻano he synthetic intermediate no ka fluoroacetone. Hoʻohana ʻia ia ma ke ʻano he catalyst no ka synthesis organik a ma ke ʻano he surfactant.
Hanana:
Hana ʻia ka synthesis o 1-bromo-3,3,3-trifluoroacetone e ka bromohydrofluoric acid method. Hoʻopili ʻia ka Acetone me ka waika hydrofluoric i loko o kahi reactor e loaʻa ai ka bromoacetone. A laila, hoʻohui ʻia ka sodium bromide i ka hui ʻana, a ua lawe ʻia ka hopena bromination e loaʻa ai ka 1-bromo-3,3,3-trifluoroacetone. Loaʻa ka huahana i makemake ʻia e ka distillation a me ka hoʻomaʻemaʻe.
ʻIke palekana:
ʻO 1-Bromo-3,3,3-trifluoroacetone he mea hoʻonāukiuki a loaʻa paha nā hopena hoʻonāukiuki ma nā maka, ka ʻili, a me ka ʻōnaehana hanu. I ka wā e hoʻohana ai, pono e lawe ʻia nā hana pale pilikino e like me nā pale maka, nā mīkina lima, a me nā mea hanu. Pono e hoʻohana ʻia ma kahi wahi e hoʻoheheʻe maikaʻi ʻia a pale i ka hoʻopili ʻana me nā mea e like me nā oxidants ikaika.
