Mawu Oyamba
Methyl butyrate. Zotsatirazi ndikuyambitsa zina mwazinthu, ntchito, njira zokonzekera ndi chidziwitso chachitetezo cha methyl butyrate:
Ubwino:
- Methyl butyrate ndi madzi oyaka omwe sasungunuka m'madzi.
- Ili ndi kusungunuka kwabwino, kusungunuka mu mowa, ma ether ndi zosungunulira zina za organic.
Gwiritsani ntchito:
- Methyl butyrate imagwiritsidwa ntchito ngati zosungunulira, plasticizer komanso zosungunulira pakupaka.
- Itha kugwiritsidwanso ntchito ngati gawo lapakati pakupanga organic pokonzekera zinthu zina.
Njira:
- Methyl butyrate imatha kukonzedwa pochita butyric acid ndi methanol pansi pa acidic. Ma reaction equation ndi awa:
CH3COOH + CH3OH → CH3COOCH2CH2CH3 + H2O
- Zomwe zimachitika nthawi zambiri zimachitika ndi kutentha ndi chothandizira (mwachitsanzo, sulfuric acid kapena ammonium sulfate).
Zambiri Zachitetezo:
- Methyl butyrate ndi madzi oyaka omwe amatha kuyaka akayatsidwa ndi malawi otseguka, kutentha kwambiri, kapena ma organic oxidants.
- Kukhudzana ndi khungu ndi maso kungayambitse kuyabwa ndi kutentha, kusamala kuyenera kuchitidwa.
- Methyl butyrate ili ndi kawopsedwe kena, kotero iyenera kupewedwa pokoka mpweya komanso kulowetsedwa mwangozi, ndikugwiritsidwa ntchito pansi pa mpweya wabwino.
- Chisamaliro chiyenera kutengedwa kuti mupewe kukhudzana ndi okosijeni, ma acid ndi alkalis mukamagwiritsa ntchito kapena kusunga.
