3) Do you apply it straight or do you thin it with something for fertilizing?
And last question
How can you tell if you have all the methanol out of it?
1) NaOH based glycerol without the Methanol is a very good weed killer, [it's the Sodium that kills]
2) You would not HAVE to recover the Methanol from the glycerol, [ it will soon evaporate in a short time] It just makes economic sense to recover as much as you can.......
3) I use it on my alfalfa fields, mix it 50/50 with water, and apply at 8 gal per acre.
Last question, Once you start recovering the Methanol [ which ever method you use] it will slowly stop producing methanol, when it quits "dripping" it's done
