Hoʻolauna

ʻO ka S-(-)-2-chloropropionic acid he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:

 

Pono: S-(-)-2-chloropropionic acid he wai waihoʻoluʻu me ka ʻala ʻala. Hiki ke hoʻoheheʻe ʻia i ka wai a me ka ethanol a hiki ʻole ke hoʻoheheʻe ʻia i ka ether. Ma ka lumi wela, loaʻa iā ia kahi kaomi mahu.

 

Hoʻohana: S-(-)-2-chloropropionic acid ka mea maʻamau i hoʻohana ʻia ma ke ʻano he reagent, catalyst a me waena o ka synthesis organik.

 

Kaʻina hoʻomākaukau: ʻElua mau ʻano hoʻomākaukau nui o ka S-(-)-2-chloropropionic acid. ʻO kekahi ala, ʻo ia ke kiʻi ʻana i ka paʻakai sodium o S-(-)-2-chloropropionate ma ka hopena o ka phenylsulfonyl chloride a me ka sodium ethanol albutan, a laila hoʻokaʻina ia e hoʻokumu i ka huahana i koho ʻia. ʻO kekahi ala ʻē aʻe ʻo ka chlorinate e ka hexanone a me ka hydrogen chloride i mua o kahi oxidant, a ukali ʻia e ka acidification e loaʻa ai ka huahana i koho ʻia.

 

ʻIke palekana: S-(-)-2-chloropropionic acid he mea hoʻonāukiuki a pono e pale ʻia i ka pili ʻana me ka ʻili a me nā maka. Pono e hoʻohana ʻia nā mea pale kūpono, e like me nā mīkina lima a me nā maka aniani i ka wā e hana ai. E kūʻai i kahi wahi paʻa i ka ea, mamao mai ke ahi a me nā mea oxidants.
