AR
LABOR
122002104
Glycerol 99% AR Grade Reagent
Cas Number:56-81-5
Formula:C3H8O3
Molar Mass:92.09
EC Number:200-289-5
Physicochemical properties：
Colorless and clear viscous liquid. Odorless. It can absorb moisture from the air and also absorb hydrogen sulfide, hydrogen cyanide and sulfur dioxide. Neutral to litmus. Long-term placement at a low temperature of 0 ° C can form a rhombohedral crystal with a melting point of 17.8 ° C. In the case of strong oxidants such as chromium trioxide, potassium chlorate, potassium permanganate can cause burning and explosion. It can be miscible with water and ethanol. 1 part of this product can be dissolved in 11 parts of acetic acid.
Usage:
Gas chromatographic fixative (the maximum use temperature is 75 ° C, solvent methanol), separation and analysis of low boiling oxygenates, amines, nitrogen or oxygen heterocyclic compounds.It can completely separate 3-methylpyridine (boiling point 144.14 ° C) and 4 -methylpyridine (boiling point 145.36 ° C). Suitable for the analysis of aqueous solutions. Solvent.
Packing:
500ml/25L/200L
