Kupu Whakataki

Ko te waikawa 3-Methyl-2-oxobutyric, e mohiotia ana ko te tert-butoxypropionic acid, TBAOH, he puhui waro.

Kounga:

Ko te waikawa 3-Methyl-2-oxobutyric he wai kore tae ki te kowhai kowhai me te kakara rereke. Ka taea te whakarewa i roto i te wai me te maha o nga whakarewa pararopi, engari karekau i roto i nga whakarewa kore-polar penei i te petroleum ethers.

Whakamahia:

Ka whakamahia te waikawa 3-Methyl-2-oxobutyric hei whakakorikori kawakore i roto i te whakahiato waro, ina koa i nga tauhohenga whakakapi. Ka taea te whakakorikori i nga tauhohenga penei i te esterification, te etherification, te amidation, te taapiri olefin, me etahi atu. Ka taea hoki te whakamahi hei whakakorikori wai-waahanga hei whakakorikori i nga tauhohe penei i te waiora, te hauwai, me te alkydation.

Tikanga:

Ka taea te whiwhi waikawa 3-Methyl-2-oxobutyric ma te tauhohe i te propanol me te konutai tert-butoxide (tert-butanol me te konutai hydroxide ranei). Ko te mahi motuhake ko te tauhohe i te propanol me te tert-butyl konutai waikura i te pāmahana e tika ana, katahi ka whiwhi te hua ma te whakakore.

Mōhiohio Haumaru:

Ko te waikawa 3-Methyl-2-oxobutyric he mea whakapataritari me te pirau, me karo atu i te pa atu ki te kiri, ki nga kanohi, me te waahanga manawa. Me mau nga karapu whakamarumaru, nga karaehe me nga kanohi kanohi i te wa e whakamahia ana. Mena ka pa atu ki a koe, horoia ki te nui o te wai, ka rapu wawe i nga mahi hauora. Me penapena ki roto i te waahi hauhautanga me te hau, kia matara atu i te ahi me nga waiora.
