2-Furoyl chloride(CAS#527-69-5)

Hoʻolauna

ʻO Furancaryl chloride.

ʻAno maikaʻi:

ʻO ka Furancaryl chloride he wai waihoʻoluʻu ʻole me ka ʻala ʻala. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe maʻamau e like me ka ethanol, ether a me benzene. Hoʻopili ia me ka wai e hana i ka waikawa furanoic a hoʻokuʻu i ke kinoea hydrogen chloride.

E hoʻohana:

Hoʻohana pinepine ʻia ʻo Furancaryl chloride ma ke ʻano he reagent koʻikoʻi i ka synthesis organik. Hiki ke hoʻohana ʻia ma ke ʻano he acylation reagent no nā hopena acylation e hoʻokomo i nā pūʻulu furancarbyl i loko o nā pūhui ʻē aʻe.

Hanana:

Hiki ke loaʻa ka Furazyl chloride ma ka hana ʻana i ka furanoic acid me ka thionyl chloride. Hoʻopili ka ʻakika Furancarboxylic me ka thionyl chloride i loko o kahi mea hoʻoheheʻe inert e like me ka methylene chloride e loaʻa ai ka furoformyl sulfoxide. Eia hou, ma ke alo o ka thionyl chloride, hoʻohana ʻia kahi mea hoʻoheheʻe ʻakika (e laʻa, phosphorus pentoxide) e hoʻomehana i ka hopena e hoʻohua ai i ka furanyl chloride.

ʻIke palekana:

ʻO ka furanyl chloride kahi mea ʻino e hoʻonāukiuki a ʻino. Inā pili me ka ʻili a me nā maka, holoi koke me ka wai nui. Pono e pale ʻia ka inhalation o kāna mau mahu i ka wā e hana ai a pono e hoʻohana ʻia nā mea pale kūpono e like me nā respirator, nā mīkina lima a me nā maka aniani inā pono. E mālama iā ia i loko o kahi pahu paʻa i ka ea, ma kahi mamao aku i nā oxidants a me nā wela kiʻekiʻe. I ka lawelawe ʻana i ka furanyl chloride, pono e mālama ʻia nā kaʻina hana palekana.
