Mawu Oyamba
4-Methoxy-2,5-dimethyl-3 (2H) -furanone) ndi mankhwala achilengedwe, omwe nthawi zambiri amafupikitsidwa ngati MDMF. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
- Maonekedwe: Madzi opanda mtundu mpaka otumbululuka achikasu
- Kusungunuka: Kusungunuka mu zosungunulira zambiri monga ma alcohols, ethers ndi ketones
Gwiritsani ntchito:
- MDMF nthawi zambiri imagwiritsidwa ntchito ngati kaphatikizidwe ka organic kaphatikizidwe kazinthu zosiyanasiyana.
- Itha kugwiritsidwa ntchito ngati zosungunulira komanso zosungunulira m'ma laboratories amankhwala.
Njira:
Njira yokonzekera MDMF nthawi zambiri imachitika ndi izi:
1. P-toluene imakhudzidwa ndi hydroxyacetone ya ketone mowa isomerization pansi pa acidic mikhalidwe.
2. Chotsatiracho chimapangidwa ndi methanol kupanga mankhwala a ketone mowa.
3. Mankhwala a ketone mowa amachotsedwa chifukwa cha kuchepa kwa madzi m'thupi kapena chithandizo cha mankhwala osokoneza bongo kuti apange MDMF yomwe ikufuna.
Zambiri Zachitetezo:
- MDMF imakhala ndi vuto lopweteka pakhungu ndipo iyenera kutsukidwa ndi madzi ambiri mukangokhudza.
- Kupsa mtima kwa diso ndi kuwonongeka kwa diso kumatha kuchitika ngati zilowa m'maso, ndiye muzimutsuka ndi madzi ambiri mukangokumana ndi dokotala.
- Pewani kutulutsa mpweya wa MDMF kuti mupewe kupuma.
- Kutentha kwakukulu, magwero oyatsira, ndi zopangira ma okosijeni amphamvu ziyenera kupewedwa posunga.
