I'm back Tom! I think your problem is with the condensor. You said you got some methanol from just heating the glycerol, but you were also getting some vapor from the output of the condensor. This suggests that the condensor is not cooling the vapor enough to condense it all........Check and see if the coils are touching each other, or the inside of the condensor wall. If I remember right you are not using a constant cold water source. Your water temp may not be cold enough. My water temp runs about 52 deg, have you checked your input and output temps of your cooling water? I haven't seen Phy on here for quite a while. I hope he's alright. I'll try and send him a PM and get his take on your problem. Don't give up hope yet, we'll figure out what your problem is.
Don.
