3-Chloro-4-fluorobenzyl bromide（CAS# 192702-01-5) Hoʻomaka
ʻO 3-Chloro-4-fluorobenzyl bromide he paʻa me ka ʻala ʻano like me ka bromobenzene. Loaʻa iā ia kahi helu heheʻe ma kahi o 38-39 ° C. A me kahi paila e pili ana i 210-212 ° C. Ma ka lumi wela, ua aneane hiki ke hoʻoheheʻe ʻia i ka wai, akā hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe.
E hoʻohana:
Loaʻa i ka 3-Chloro-4-fluorobenzyl bromide ka laulā o nā noi i ka synthesis organik. He mea koʻikoʻi koʻikoʻi ia no ka hoʻomākaukau ʻana i nā mea hoʻohui organik ʻē aʻe, e like me nā lāʻau lapaʻau, nā mea pena a me nā pesticides. Hoʻohana ʻia ia i ka hoʻomākaukau ʻana i nā mea pale ahi, nā mea photosensitive a me nā mea hoʻololi resin.
Hanana:
Loaʻa ka 3-Chloro-4-fluorobenzyl bromide ma ka hana ʻana i ka bromobenzene me ka tert-butyl magnesium bromide. ʻO ka mua, hoʻopili ʻia ka tert-butylmagnesium bromide me ka bromobenzene ma kahi mahana haʻahaʻa e loaʻa ai ka tert-butylphenylcarbinol. A laila, ma ka chlorination a me ka fluorination, hiki ke hoʻololi i nā hui carbinol i ka chlorine a me ka fluorine, a ua hoʻokumu ʻia ka 3-Chloro-4-fluorobenzyl bromide. ʻO ka mea hope loa, hiki ke loaʻa ka huahana i hoʻopaʻa ʻia ma ka hoʻomaʻemaʻe ʻana me ka distillation.
ʻIke palekana:
E hoʻohana i ka 3-Chloro-4-fluorobenzyl bromide me ka nānā ʻana i ka ʻona a me ka huhū. Hiki ke hoʻonāukiuki i ka ʻōnaehana hanu, ka ʻili a me nā maka. Hōʻalo i ka pili ʻana me ka ʻili, nā maka a me ka ʻōpū hanu i ka wā o ka hana. E hoʻohana i nā mea pale kūpono, e like me nā mīkina lima, nā maka maka a me nā pale maka. Eia kekahi, pono e mālama ʻia i kahi wahi maikaʻi a pale i ka hoʻopili ʻana me nā mea e like me nā oxidants ikaika. Inā ale ʻia a inhaled paha, e ʻimi koke i ka lāʻau lapaʻau. E ʻoluʻolu e heluhelu pono i nā ʻōlelo aʻoaʻo palekana ma mua o ka hoʻohana ʻana.
