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. |
