Intshayelelo
I-5-Hydroxymethylfurfural, ekwaziwa ngokuba yi-5-Hydroxymethylfurfural (HMF), yikhompawundi ephilayo eneempawu ezinuka kamnandi. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-5-hydroxymethylfurfural:
Umgangatho:
- Imbonakalo: 5-Hydroxymethylfurfural yikristale engenambala ukuya kumthubi okanye ulwelo.
- Ukunyibilika: Ukunyibilika emanzini, ethanol kunye ne-ether.
Sebenzisa:
- Amandla: I-5-Hydroxymethylfurfural nayo ingasetyenziswa njenge-precursor material for biomass energy.
Indlela:
- I-5-Hydroxymethylfurfural inokulungiswa ngokuphendula kwe-dehydration ye-fructose okanye i-glucose phantsi kweemeko ze-acidic.
Ulwazi ngoKhuseleko:
- I-5-Hydroxymethylfurfural yikhemikhali ekufuneka iphathwe ngokukhuselekileyo kwaye igweme ukudibana ngokuthe ngqo nolusu, amehlo, kunye neegesi eziphefumulayo.
- Ngexesha lokugcinwa kunye nokusetyenziswa, kufuneka kugcinwe kude nomlilo kunye nemithombo yokushisa, kwaye igcinwe kwindawo epholileyo neyomileyo.
- Xa uphethe i-5-hydroxymethylfurfural, nxiba izixhobo ezifanelekileyo zokukhusela ezifana neglavu, iindondo zokukhusela, kunye nesikhuselo sobuso esikhuselayo.
