Normal boiling point of isopropyl alcohol
WebJy329 • 7 yr. ago. The way they purify the compound, distillation, generally requires a large difference in boiling point, which suggests that glycerol (you already defined it as higher than water) has over 10 degrees difference. It's a little arbitrary, but if it's less than 10 degrees higher, it would be harder to purify via distillation.
