Intshayelelo

Isovaleric acid. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-isovaleric acid:

Umgangatho:

Imbonakalo: Ulwelo olungenambala okanye olutyheli olunevumba elibukhali elifana ne-acetic acid.

Ubuninzi: 0.94g/cm³

Ukunyibilika: Inyibilika emanzini, inokudityaniswa ne-ethanol, i-ether kunye nezinye izinyibilikisi eziphilayo.

Sebenzisa:

I-Synthesis: I-asidi ye-Isovaleric yinto ebalulekileyo ye-chemical synthesis intermediate, esetyenziswa ngokubanzi kwiindawo ezininzi zoshishino ezifana ne-organic synthesis, amayeza, i-coatings, irabha kunye neeplastiki.

Indlela:

Indlela yokulungiselela i-isovaleric acid ibandakanya ezi ndlela zilandelayo:

Ngokusebenzisa i-oxidation reaction ye-n-butanol, i-oxidation ye-n-butanol kwi-isovaleric acid iqhutyelwa ngokusebenzisa i-acidic catalyst kunye ne-oxygen.

I-Magnesium butyrate yenziwa ngokusabela kwe-magnesium butyl bromide kunye ne-carbon dioxide, ethi emva koko iguqulelwe kwi-isovaleric acid ngokusabela nge-carbon monoxide.

Ulwazi ngoKhuseleko:

I-Isovaleric acid yinto ephazamisayo, ugweme ukudibanisa nesikhumba kunye namehlo, kwaye ubeke ingqalelo ekusebenziseni iiglavu ezikhuselayo, iiglasi zokhuseleko kunye nempahla yokukhusela.

Xa usebenzisa i-isovaleric acid, i-inhalation ye-vapors yayo kufuneka igwenywe kwaye umsebenzi kufuneka uqhutywe kwindawo enomoya.

Indawo yokutshisa iphantsi, thintela ukudibana nomthombo womlilo, kwaye ugcine kude namadangatye avulekileyo kunye nemithombo yobushushu.

Kwimeko yokuvezwa ngengozi kwi-isovaleric acid, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune unyango.

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

Okulandelayo: Diethylsuccinate (CAS#123-25-1)
