Silica Gel / Sodium Acrylate – water absorbancy
« on: January 23, 2013, 07:01:17 AM »

Silica Gel and Sodium acrylate are used to absorb water at room temperature. Can they be placed in selected organic solvents overnight so as to absorb all water, the solvent fractionally distilled or slowly decanted ? 
Is the absorbancy 100 % ?
Are they compatible with common oxy / hydrocarbon solvents ?
( eg. methanol, ethanol, acetone, toluene, benzene, IPA, etc )
It is desired NOT to use metal salts eg MgSO4, CaCl2.

I would recommend using molecular sieves for drying organic solvents. There's a very good paper evaluating their efficacy. See: Drying of Organic Solvents: Quantitative Evaluation of the Efficiency of Several Desiccants
