Isingeniso

I-Isovaleric acid. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-isovaleric acid:

Ikhwalithi:

Ukubukeka: Uketshezi olungenambala noma oluphuzi olunephunga elimnandi elifana ne-acetic acid.

Ukuminyana: 0.94g/cm³

Ukunyibilika: kuncibilika emanzini, kungase futhi kuxubane ne-ethanol, i-ether nezinye izincibilikisi eziphilayo.

Sebenzisa:

I-synthesis: I-Isovaleric acid iyi-chemical synthesis ephakathi nendawo, esetshenziswa kakhulu emikhakheni eminingi yezimboni efana ne-organic synthesis, imithi, okokumboza, irabha namapulasitiki.

Indlela:

Indlela yokulungiselela i-isovaleric acid ihlanganisa izindlela ezilandelayo:

Ngokusabela kwe-oxidation ye-n-butanol, ukufakwa kwe-n-butanol ku-isovaleric acid kwenziwa kusetshenziswa i-acidic catalyst nomoya-mpilo.

I-Magnesium butyrate yakhiwa ukusabela kwe-magnesium butyl bromide ne-carbon dioxide, eguqulwa ibe yi-isovaleric acid ngokusabela ne-carbon monoxide.

Ulwazi Lokuphepha:

I-Isovaleric acid iyinto edlayo, gwema ukuthintana nesikhumba namehlo, futhi unake ukusetshenziswa kwamagilavu okuzivikela, izibuko zokuphepha nezingubo zokuzivikela.

Uma usebenzisa i-isovaleric acid, ukuhogela umhwamuko wayo kufanele kugwenywe futhi ukusebenza kufanele kwenziwe endaweni enomoya omuhle.

Indawo yokuthungela iphansi, gwema ukuthintana nomthombo womlilo, futhi ugcine kude namalangabi avulekile nemithombo yokushisa.

Esimeni sokuchayeka ngengozi ku-isovaleric acid, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.

Okwedlule: I-Methyl p-tert-butylphenylacetate (CAS#3549-23-3)

Olandelayo: I-Diethylsuccinate (CAS#123-25-1)
