To explain why glycerol (propane-1,2,3-triol) is more viscous than ethylene glycol (ethane-1,2-diol), we will analyze their structures and the implications for hydrogen bonding.1. Identify the Structures: - Glycerol (propane
Moreover, the MEs can be separated and recycled for further etherification. Sign in to download full-size image Figure 12.11. Etherification of glycerol with iso-butene. Glycerol is a tri-alcohol fully miscible with water, with a high boiling point and very viscous. On the other side, iso-...
Glycerol is a colorless, odorless, viscous liquid contains three hydroxyl groups propane-1,2,3-triol, which are responsible for its hygroscopic character and solubility in water. It is soluble in different polar liquids, such as methanol, ethanol and insoluble in fatty oils, in higher alcohols,...
Pure glycerol appears as colorless, odorless and sweet viscous liquid. Boiling point: 290 ° C, melting point: 17.9 ° C, the relative density: 1.2613. It can be miscible with water infinitely. It can be dissolved in 11 times ethyl acetate, about 500 times ether. It is insoluble in benze...

Glycerol is a clear, colourless, viscous, sweet-tasting liquid. Glycerin is an important basic organic raw material, which is widely used in industry, medicine and daily life. Currently, it has more than 1700 USES, mainly used in medicine, cosmetics, alkyd resin, tobacco,...
Based on this conjecture, the compression modulus of the liposomes decreased from 18.5mN/m in water to 8.13 mM/m in the presence of 62% (w/w) glycerol. This large decrease in the modulus is indicative of a weakening of the membrane, which would make it more sensitive to external ...
