I'm looking to remove about 10% of methanol from DMAc in order to do the next step in a reaction. I am aware that DMAc and MeOH do not form a stable azeotrope, but also have read that the vapor pressure of MeOH is significantly higher than that of DMAc, which gives me some hope in removing it with a bit of heat and vacuum. Has anybody worked with this system and tried it before? Any suggestions are welcome..
