3-methyl-2-oxobutyric acid (CAS# 759-05-7)
Isingeniso
I-3-Methyl-2-oxobutyric acid, eyaziwa nangokuthi i-tert-butoxypropionic acid, i-TBAOH, iyinhlanganisela yezinto eziphilayo.
Ikhwalithi:
I-3-Methyl-2-oxobutyric acid iwuketshezi olungenambala ukuya kokuphuzi okuphaphathekile olunephunga elingavamile. Ingancibilika emanzini nasezincibilikisini eziningi eziphilayo, kodwa ingancibiliki kuzincibilikisi ezingezona ze-polar njenge-petroleum ethers.
Sebenzisa:
I-3-Methyl-2-oxobutyric acid ivame ukusetshenziswa njenge-alkali catalyst ku-organic synthesis, ikakhulukazi ekuphenduleni esikhundleni. Ingakwazi ukugqugquzela ukusabela okufana ne-esterification, i-etherification, i-amidation, i-olefin ukwengeza, njll. Ingasetshenziswa futhi njenge-catalyst yesigaba soketshezi ukuze ibangele ukusabela okufana ne-oxidation, i-hydrogenation, ne-alkydation.
Indlela:
I-3-Methyl-2-oxobutyric acid ingatholakala ngokuphendula i-propanol nge-sodium tert-butoxide (noma i-tert-butanol ne-sodium hydroxide). Isinyathelo esiqondile ukusabela i-propanol nge-tert-butyl sodium oxide ekushiseni okufanelekile, bese umkhiqizo utholwa ngokuvalwa.
Ulwazi Lokuphepha:
I-3-Methyl-2-oxobutyric acid iyacasula futhi iyagqwala futhi kufanele igwenywe ukuthintana nesikhumba, amehlo, kanye nomgudu wokuphefumula. Amagilavu okuzivikela, izibuko, namamaski kufanele kugqokwe ngesikhathi sokusetshenziswa. Uma uthintana ngephutha, hlambulula ngamanzi amaningi futhi ufune usizo lwezokwelapha ngokushesha. Kufanele igcinwe endaweni epholile, engenawo umoya, kude nomlilo nama-oxidants.
