hey guys...quick ?..if you dont use water in your process and recover meth.why would you have to worry about purity


for the record...just did 2nd batch with my gl 1day..no prewash..recovered almost 2gal from 50 gal of finished bio.saving gly and plan to recover using same reactor every 3 batches.which is between 45-50 gal gly

Both the transesterification reaction and methnoxide mixing produce significant amounts of water.

okay,so if i take my temp up too high i will likely have water in my recovered meth,correct.also,if someone was to have water in meth and use it on upcoming batch,are they heading for trouble.i was hoping recovery wasnt going to be complicated,gl suggests taking it to about 190f...thanks....will

The problem with water in your methanol will be that the next time you use your recovered methanol it will make a wack load of soap. This is why we try to minimize water in biodiesel. It is needed for hydrolysis.

Keep the top of your temperature head on the still close to 64.7C. This is the boiling point of methanol.
