Intangiriro
4-Methoxy-2,5-dimethyl-3 (2H) -furanone) ni ifumbire mvaruganda, ikunze kwitwa MDMF. Ibikurikira nintangiriro yimiterere yabyo, imikoreshereze, uburyo bwo gutegura namakuru yumutekano:
Ubwiza:
- Kugaragara: Ibara ritagira ibara ryijimye
- Gukemura: Gukemura mumashanyarazi menshi nka alcool, ethers na ketone
Koresha:
- MDMF ikoreshwa kenshi nkigihe cyo guhuza ibinyabuzima kugirango ikomatanyirize hamwe.
- Irashobora gukoreshwa nka solvent na reaction muri laboratoire yimiti.
Uburyo:
Uburyo bwo gutegura MDMF muri rusange bukorwa nintambwe zikurikira:
1. P-toluene ikoreshwa na hydroxyacetone kugirango ketone alcool isomerisation mubihe bya acide.
2. Ibicuruzwa bivamo noneho bigakorwa hamwe na methanol kugirango habeho ibinyobwa bya ketone.
3. Ibinyobwa bya ketone bya ketone bigabanya umwuma bitewe no kubura umwuma cyangwa kuvura imiti igabanya ingufu kugirango bibyare umusaruro MDMF.
Amakuru yumutekano:
- MDMF igira ingaruka mbi kuruhu kandi igomba kwozwa namazi menshi mukimara guhura.
- Kurakara kw'amaso no kwangirika kw'amaso birashobora guterwa iyo byinjiye mumaso, kwoza n'amazi menshi ako kanya ukimara kubonana na muganga.
- Irinde guhumeka imyuka ya MDMF kugirango wirinde guhumeka.
- Ubushyuhe bwo hejuru, inkomoko yumuriro, hamwe ningingo zikomeye za okiside bigomba kwirindwa mugihe ubitse.
