Intshayelelo
I-Methyl butyrate. Oku kulandelayo kukwazisa kwezinye iipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-methyl butyrate:
Umgangatho:
- I-Methyl butyrate lulwelo olunokutsha olungenakunyibilika kancinci emanzini.
-Inonyibiliko olulungileyo, lunyibilika kwii-alcohols, ii-ethers kunye nezinye izinyibilikisi eziphilayo.
Sebenzisa:
I-Methyl butyrate isetyenziswa ngokuqhelekileyo njenge-solvent, i-plasticizer kunye ne-diluent kwi-coatings.
- Isenokusetyenziswa njengendawo ephakathi kwi-organic synthesis ukulungiselela ezinye iikhompawundi.
Indlela:
- I-Methyl butyrate inokulungiswa ngokuphendula i-butyric acid kunye ne-methanol phantsi kweemeko ze-acidic. I-reaction equation imi ngolu hlobo lulandelayo:
CH3COOH + CH3OH → CH3COOCH2CH2CH3 + H2O
- Ukusabela kudla ngokuqhutyelwa ngokufudumeza nge-catalyst (umzekelo, i-asidi ye-sulfuric okanye i-ammonium sulfate).
Ulwazi ngoKhuseleko:
I-Methyl butyrate lulwelo olunokutsha olunokutsha xa luvezwe kumadangatye avulekileyo, amaqondo obushushu aphezulu, okanye i-organic oxidants.
- Ukudibana nolusu kunye namehlo kunokubangela ukucaphuka kunye nokutshisa, kufuneka kuthathwe amanyathelo okhuseleko.
- I-Methyl butyrate inobuthi obuthile, ngoko kufuneka igwenywe ukuphefumla kunye nokungena ngengozi, kwaye isetyenziswe phantsi kweemeko zomoya.
- Ukunyamekela kufuneka kuthathwe ukukhusela ukudibanisa ne-oxidants, i-acids kunye ne-alkali xa usebenzisa okanye ukugcinwa.
