Intshayelelo
I-Methyl propionate, eyaziwa ngokuba yi-methoxyacetate. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-methyl propionate:
Umgangatho:
- Imbonakalo: I-Methyl propionate lulwelo olungenambala olucacileyo kunye nevumba elikhethekileyo.
- Ukunyibilika: I-Methyl propionate inyibilika ngakumbi kwi-alcohol e-anhydrous kunye nezinyibilikisi ze-ether, kodwa ayinyibiliki kancinci emanzini.
Sebenzisa:
- Ukusetyenziswa kwamashishini: I-Methyl propionate yi-solvent ebalulekileyo yezinto eziphilayo ezisetyenziswa ngokubanzi kwiingubo, ii-inki, i-adhesives, i-detergents kunye namanye amashishini.
Indlela:
Amalungiselelo e-methyl propionate ahlala esterified:
CH3OH + CH3COOH → CH3COOCH2CH3 + H2O
Phakathi kwabo, i-methanol kunye ne-acetic acid isabela phantsi kwesenzo se-catalyst ukwenza i-methyl propionate.
Ulwazi ngoKhuseleko:
- I-Methyl propionate iyilwelo olunokutsha kwaye kufuneka igcinwe kude namadangatye avulekileyo kunye namaqondo obushushu aphezulu.
- Ukuvezwa kwi-methyl propionate kunokubangela ukucaphuka kwamehlo kunye nolusu, ngoko kufuneka kuthathwe amanyathelo okhuseleko.
• Kuphephe ukuphefumla umphunga wemethyl propionate kwaye kufuneka usebenze kwindawo engena umoya.
- Kwimeko yokungenwa ngengozi okanye ukuphefumla, funa unyango ngokukhawuleza.
