Hi Mike,Hi Joe, I am completely agree with you on point one,Mike,I`v experienced it on my own neck.Point two-you are right about silica,but I gave it up-it is a mess when it comes to recovering the stuff;nevertheless it is useful to absorb any water content leftover,just pump it trough the vessel with silica long enough. Point 3 -heating always helps! Point 4 -I am not American,I dint know what ISA means-isopropil alcohol? Point 5 -I closed the circle too-I am using a small Rielo burner/3l/h/8bar/ to heat everything including the room with two SS pipes spiraling around the flame for heat exchange-the first is circulating oil for higher temp/distilling glycerin/ and the second is with water for heating all vessels.Did I mentioned that I put rock wool insulation everywhere. There is one more thing-I made the reactor and the dryer airtight, capable of vacuum and pressure, so I can work at temp well over 70 degrees C and put under vacuum when evaporating is necessary (and not to worry about any methanol fumes!). I started researching the so-cold co-solvent processing with tetrahydrofuran-I`ll tell you guys,it is an expensive stuff!The only plus is that it can be recovered almost completely.I`ll keep you informed how far I am trough. I will fully support the idea to co-experimenting and sharing the results-just tell me what I can do to help! Good luck to everyone! Rumen
