Mawu Oyamba
Methyl propionate, yemwenso amadziwika kuti methoxyacetate. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha methyl propionate:
Ubwino:
- Maonekedwe: Methyl propionate ndi madzi osawoneka bwino komanso onunkhira apadera.
- Kusungunuka: Methyl propionate imasungunuka kwambiri mu zakumwa zoledzeretsa za anhydrous ndi zosungunulira za ether, koma sizisungunuka m'madzi.
Gwiritsani ntchito:
- Kugwiritsa ntchito mafakitale: Methyl propionate ndi chinthu chofunikira kwambiri chosungunulira chomwe chimagwiritsidwa ntchito kwambiri popaka, inki, zomatira, zotsukira ndi mafakitale ena.
Njira:
Kukonzekera kwa methyl propionate nthawi zambiri kumatsimikiziridwa:
CH3OH + CH3COOH → CH3COOCH2CH3 + H2O
Pakati pawo, methanol ndi asidi acetic amachita pansi pa chothandizira kupanga methyl propionate.
Zambiri Zachitetezo:
- Methyl propionate ndi madzi oyaka moto ndipo ayenera kusungidwa kutali ndi moto wotseguka komanso kutentha kwambiri.
- Kuwonetsedwa ndi methyl propionate kungayambitse kupsa mtima kwa maso ndi khungu, chifukwa chake muyenera kusamala.
- Pewani kutulutsa mpweya wa methyl propionate ndipo uyenera kugwirira ntchito pamalo olowera mpweya wabwino.
- Ngati walowetsedwa mwangozi kapena kupumira mpweya, pitani kuchipatala mwamsanga.
