3-methyl-2-oxobutyric acid （CAS# 759-05-7)

Hoʻolauna

ʻO 3-Methyl-2-oxobutyric acid, i ʻike ʻia ʻo tert-butoxypropionic acid, TBAOH, he mea hoʻohuihui.

ʻAno maikaʻi:

ʻO ka 3-Methyl-2-oxobutyric acid he wai waihoʻoluʻu a ʻeleʻele melemele me kahi ʻala ʻokoʻa. Hiki ke hoʻoheheʻe ʻia i loko o ka wai a me nā mea hoʻoheheʻe organik he nui, akā ʻaʻole hiki ke hoʻoheheʻe ʻia i nā solvents non-polar e like me ka petroleum ethers.

E hoʻohana:

Hoʻohana pinepine ʻia ka 3-Methyl-2-oxobutyric acid ma ke ʻano he catalyst alkali i ka synthesis organik, ʻoi aku hoʻi i nā hopena hoʻololi. Hiki iā ia ke hoʻololi i nā hopena e like me ka esterification, etherification, amidation, olefin hoʻohui, a me nā mea ʻē aʻe.

Hanana:

Hiki ke loaʻa ka 3-Methyl-2-oxobutyric acid ma ka hana ʻana i ka propanol me ka sodium tert-butoxide (a i ʻole tert-butanol a me ka sodium hydroxide). ʻO ka hana kikoʻī e hana i ka propanol me ka tert-butyl sodium oxide ma kahi mahana kūpono, a laila loaʻa ka huahana ma ka hoʻopau ʻana.

ʻIke palekana:

ʻO ka 3-Methyl-2-oxobutyric acid he mea hoʻonāukiuki a ʻino a pono e pale ʻia mai ka pili ʻana me ka ʻili, nā maka, a me ka ʻōpū hanu. Pono e hoʻohana ʻia nā mīkina lima pale, nā maka aniani, a me nā masks i ka wā e hoʻohana ai. Inā loaʻa ka pilikia, holoi me ka wai nui a ʻimi koke i ka lāʻau lapaʻau. Pono e mālama ʻia ma kahi ʻoluʻolu a me ka ea, kahi mamao mai ke ahi a me nā mea oxidants.
