Intshayelelo

I-Isobutyric acid, eyaziwa ngokuba yi-2-methylpropionic acid, i-organic compound. Oku kulandelayo sisingeniso esicacileyo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-isobutyric acid:

Umgangatho:

Imbonakalo: Ulwelo olungenambala kunye nevumba elimnandi elikhethekileyo.

Ubuninzi: 0.985 g/cm³.

Ukunyibilika: Ukunyibilika emanzini kunye nezinyibilikisi ezininzi eziphilayo.

Sebenzisa:

Izinyibilikisi: Ngenxa yokunyibilika kwayo okulungileyo, iasidi ye-isobutyric isetyenziswa kakhulu njengesinyibilikisi, ngakumbi kwiipeyinti, iipeyinti, kunye nezicoci.

Indlela:

Indlela eqhelekileyo yokulungiselela i-isobutyric acid ifunyenwe nge-oxidation ye-butene. Le nkqubo iqhutywe yi-catalyst kwaye iqhutyelwa kumaqondo aphezulu kunye noxinzelelo.

Ulwazi ngoKhuseleko:

I-Isobutyric acid yikhemikhali edlayo enokubangela ukucaphuka kunye nomonakalo xa udibana nolusu kunye namehlo, kwaye amanyathelo okhuseleko afanelekileyo kufuneka anxitywe xa usebenzisa.

Ukuvezwa kwexesha elide kunokubangela ukoma, ukuqhekeka, kunye nokungaguquki komzimba.

Xa ugcina kwaye uphatha i-isobutyric acid, kufuneka igcinwe kude namadangatye avulekileyo kunye namaqondo okushisa aphezulu ukukhusela umlilo kunye nobungozi bokuqhuma.

Ngaphambili: 5-Methyl-2-hepten-4-enye(CAS#81925-81-7)

Okulandelayo: 1,2,3,5,6,7-Hexahydro-1,1,2,3,3-pentamethyl-4H-inden-4-enye(CAS#33704-61-9)
