Diethylene glycol in WINE question help please CHEMISTRY gr 12
Distillation is probably the way to go but I don't know how to do this using boiling points. This looks like the right way to do it because I was reading stuff about alcohols, aldehydes, ethers, ketones, naming these and then their would be a property section where it would talk about boiling...- aisha
