Nhanganyaya
4-Methoxy-2,5-dimethyl-3 (2H) -furanone) inhengo yehupenyu, inowanzopfupikiswa seMDMF. Iyi inotevera sumo kune chimiro chayo, kushandiswa, nzira yekugadzirira uye ruzivo rwekuchengetedza:
Hunhu:
-Kutaridzika: isina ruvara kune yakachenuruka yero mvura
- Solubility: Inonyungudika mune yakawanda organic solvents senge madoro, ethers uye ketoni
Shandisa:
- MDMF inowanzoshandiswa sepakati mune organic synthesis yekubatanidza kwakasiyana organic komisheni.
- Inogona kushandiswa sechinhu chinonyungudutsa uye chinogadzirisa mumakemikari marabhoritari.
Nzira:
Iyo nzira yekugadzirira yeMDMF inowanzoitwa nematanho anotevera:
1. P-toluene inobatwa ne hydroxyacetone ye ketone alcohol isomerization pasi pemamiriro e acidic.
2. Chigadzirwa chacho chinobva chaitwa ne methanol kuti iite ketone alcohol compounds.
3. Iro ketone doro rinosanganiswa nehutachiona hwekushaya mvura kana kurapwa kwechirwere chekushaya mvura kuti chibudise chinangwa cheMDMF.
Zvekuchengetedza
- MDMF ine simba rinogumbura paganda uye inofanira kushambidzwa nemvura yakawanda pakarepo mushure mekubatana.
- Kushatirwa kweziso uye kukuvara kwemaziso kunogona kukonzerwa kana ikapinda mumaziso, saka sukurudza nemvura yakawanda nekukurumidza mushure mekusangana uye bvunza chiremba.
- Dzivisa kufema mhute yeMDMF kudzivirira kutsamwa kwekufema.
-Kupisa kwepamusoro, zvitubu zvemoto, uye yakasimba oxidizing agents zvinofanirwa kudzivirirwa kana uchichengeta.
