1,2,3-Propanetriol is a trihydric alcohol. It is a clear, viscous liquid, with a sweet taste. It has low volatility and high boiling point because the molecules form strong hydrogen bonds. 1,2,3-propanetriol is hygroscopic, which means that it can pick up and give off water. It might absorb vaporous water from the air up to 50 % of its weight. It is completely miscible with water but insoluble in hydrocarbons. The name glycerine refers to the quality that contains more than 95 % glycerol.

3. Glycerol Usage And Synthesis

Chemical Properties: Clear, colorless, viscous liquid

Usage: Glycerol is used both in sample preparation and gel formation for polyacrylamide gel electrophoresis. Glycerol (5-10%) increases the density of a sample so that the sample will layer at the bottom of a gel's sample well. Glycerol is also used to aid in casting gradient gels and as a protein stabilizer and storage buffer component.

General Description: A colorless to brown colored liquid. Combustible but may require some effort to ignite. Residual sodium hydroxide (lye) causes crude material to be corrosive to metals and/or tissue.

Air & Water Reactions: Hygroscopic. Water soluble.

Reactivity Profile: GLYCERINE is incompatible with strong oxidizers. Glycerol is also incompatible with hydrogen peroxide, potassium permanganate, nitric acid + sulfuric acid, perchloric acid + lead oxide, acetic anhydride, aniline + nitrobenzene, Ca(OCl)2, CrO3, F2 + PbO, KMnO4, K2O2, AgClO4 and NaH. A mixture with chlorine explodes if heated to 158-176° F. Glycerol reacts with acetic acid, potassium peroxide, sodium peroxide, hydrochloric acid, (HClO4 + PbO) and Na2O2. Contact with potassium chlorate may be explosive. Glycerol also reacts with ethylene oxide, perchloric acid, nitric acid + hydrofluoric acid and phosphorus triiodide.

Health Hazard: No hazard

Fire Hazard: Glycerol is combustible.
