Distillation with toluene and/or stand over 3A molecular sieves (in melt or solution)
Hello Sangh,
You can distil the solvents and store in molecular sieves under flushed nitrogen or argon gases.
Always store in dark and dry place when not in use,
thankyou Anderi Rogoza , but which solvent stand over 3 A molecular sieve?
Standing is more correct, probably. All this substances above 350C in neat (liquid) condition or in solvent ( toluene, for instance) are suitable for 3A molecular sieves drying. Azeotropic distillation with toluene is relative simple and cheap method of drying; molecular sieves are more effective dessicant.
You can dry p-cresol by adding P2O5 as desiccant; preferably under vacuum. Either diphenyl ether (or diphenyl oxide) and diphenylmethane can be dried by adding CaCl2 as desiccant; also preferably under vacuum.
