Physical thiab Chemical Properties Cov khoom siv tshuaj 3-ethoxy-1,2-propanediol (3-ethoxy-1,2-propanediol), yog ib qho luv luv-chain aliphatic ether hnyav ntawm glycerol, viscous, ruaj khov dej-absorbing kua, tsis muaj xim thiab tsis muaj ntxhiab, miscible nrog dej , ethanol thiab ntau yam organic solvents.
Siv Siv 3-ethoxy -1, 2-propanediol yog ib qho tseem ceeb nruab nrab rau kev sib txuas ntawm dioxolane compounds. Dioxolane tebchaw yog cov khoom siv tshuaj lom neeg zoo heev, uas tuaj yeem sib xyaw nrog diesel ua roj. Dioxolane cov tebchaw uas muaj 6-8 carbon atoms yog cov khoom sib xyaw oxidation zoo heev, thiab kev sib xyaw nrog cov roj diesel tuaj yeem txo cov emissions ntawm cov khoom thiab NOx los ntawm diesel combustion.
