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

Mawu Oyamba

3-Methyl-2-oxobutyric acid, yomwe imadziwikanso kuti tert-butoxypropionic acid, TBAOH, ndi mankhwala achilengedwe.

Ubwino:

3-Methyl-2-oxobutyric acid ndi madzi achikasu mpaka otumbululuka okhala ndi fungo lachilendo. Ikhoza kusungunuka m'madzi ndi zosungunulira zambiri za organic, koma osasungunuka mu zosungunulira zopanda polar monga petroleum ethers.

Gwiritsani ntchito:

3-Methyl-2-oxobutyric acid nthawi zambiri amagwiritsidwa ntchito ngati chothandizira cha alkali mu kaphatikizidwe ka organic, makamaka m'malo momwe zimachitikira. Iwo akhoza kulimbikitsa zimachitikira monga esterification, etherification, amidation, olefin Kuwonjezera, etc. Angagwiritsidwenso ntchito ngati madzi-gawo chothandizira kuti catalyze zimachitikira monga makutidwe ndi okosijeni, hydrogenation, ndi alkydation.

Njira:

3-Methyl-2-oxobutyric acid imatha kupezeka pochita propanol ndi sodium tert-butoxide (kapena tert-butanol ndi sodium hydroxide). Gawo lenileni ndikuchitapo kanthu ndi propanol ndi tert-butyl sodium oxide pa kutentha koyenera, ndiyeno mankhwalawa amapezedwa ndikuzimitsa.

Zambiri Zachitetezo:

3-Methyl-2-oxobutyric acid imakwiyitsa komanso ikuwononga ndipo iyenera kupewedwa kuti isakhudzidwe ndi khungu, maso, ndi kupuma. Magolovesi odzitchinjiriza, magalasi, ndi masks ayenera kuvala mukamagwiritsa ntchito. Mukakhudzana mwangozi, muzimutsuka ndi madzi ambiri ndikupita kuchipatala mwamsanga. Iyenera kusungidwa pamalo ozizira, opanda mpweya wabwino, kutali ndi moto ndi okosijeni.
