Mawu Oyamba
(5h) furanone ndi organic pawiri ndi mankhwala chilinganizo C8H12O3 ndi molecular kulemera kwa 156.18g/mol. Ndi madzi achikasu otumbululuka opanda utoto okhala ndi kutsekemera kwapadera kwa shuga. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
-Maonekedwe: Madzi opanda mtundu mpaka owala achikasu
-Posungunuka: -7 ℃
- Malo otentha: 171-173 ℃
-Kuchulukana: pafupifupi. 1.079g/cm³
-Kusungunuka: Kutha kusungunuka m'madzi, ethanol ndi zosungunulira za Ether
-Kukhazikika: kukhazikika pa kutentha kwa chipinda
Gwiritsani ntchito:
-Zakudya zowonjezera: Chifukwa cha kutsekemera kwake kwapadera, zimagwiritsidwa ntchito ngati chakudya chokometsera chakudya, makamaka maswiti, jamu ndi mchere.
-Zonunkhira: Zitha kugwiritsidwa ntchito ngati zokometsera kuti chakudya chikhale chokoma chapadera.
-mafuta onunkhira: monga chimodzi mwazinthu zopangira mafuta onunkhira.
Njira:
(5h) furanone ikhoza kukonzedwa ndi njira zotsatirazi:
1. Ndi 3-methyl -2-pentanone monga chiyambi, 3-hydroxy -4-methyl -2-pentanone inapezedwa ndi keto-alcohol reaction.
2.3-hydroxy -4-methyl -2-pentanone imayendetsedwa ndi etherifying agent (monga diethyl ether) kuti apange mankhwala a etherification.
3. The etherification mankhwala ndi pansi catalysis asidi ndi deoxidation anachita kupeza furanone (5h).
Zambiri Zachitetezo:
-(5h) furanone imatengedwa kuti ndi yotetezeka kuti igwiritsidwe ntchito nthawi zonse, koma ikhoza kukwiyitsa khungu ndi maso pazigawo zambiri.
-Kugwiritsa ntchito kuyenera kutsata njira zodzitetezera, kupewa kukhudzana ndi khungu ndi maso, komanso kukhala ndi malo abwino ogwirira ntchito.
- Tsatirani njira zoyenera zotetezera mukamagwiritsa ntchito, ndikuzisunga pamalo owuma, ozizira, kutali ndi moto ndi oxidizing agents.
