IiPropati zoMzimba kunye nezeMichiza Iimpawu zeMichiza i-3-ethoxy-1,2-propanediol (3-ethoxy-1,2-propanediol), i-short-chain aliphatic ether solvent ye-glycerol, i-viscous, i-stable water-efunxa ulwelo, engenambala kwaye ayinavumba, ixutywe namanzi. , i-ethanol kunye neentlobo ezahlukeneyo ze-solvents eziphilayo.
Sebenzisa Isebenzisa i-3-ethoxy -1, i-2-propanediol yinto ebalulekileyo ephakathi kwi-synthesis ye-dioxolane compounds. Iikhompawundi zeDioxolane ziyimveliso yemichiza eluncedo kakhulu, enokuxutywa nedizili njengamafutha. Iikhompawundi ze-Dioxolane eziqulethe i-athomu ze-carbon ezi-6-8 ziyimixube egqwesileyo ye-oxidation, kwaye ukuxuba namafutha edizili kunokunciphisa Kakhulu ukukhutshwa kwamasuntswana aqinileyo kunye ne-NOx ebangelwa kukutsha kwedizili.
