solubility of MeOH in toluene/xylene


2 quick questions...

does anyone know what the solubility of MeOH in toluene/xylene is?

what about the solubility of 50% h2o, 50% MeOH in toluene/xylene... can you expect a small percentage of MeOH to still be in the toluene/xylene?

Methanol, and also ethanol, when anhydrous, is usually infinitely miscible in all proportions with low molecular weight hydrocarbons, including toluene and xylenes. However, there are two-phase regions in the ternary systems if water is introduced. Perrys Chemical Engineers Handbook has phase diagrams for some such ternary systems.
