Proposed Methanol/Methoxide recovery from the glycerol/byproduct layer

Proposed Methanol/Methoxide recovery from the glycerol/byproduct layer.
Because Methanol/Methoxide in the precipitate (glycerol/byproduct layer) boils at lower temperatures than water, and a vacuum lowers the required boiling temperature of all liquids.
Maybe this can be used as the basis of Methanol/Methoxide recovery from the glycerol/byproduct layer.
This is possible in theory and the vacuum can also be produced at the same time in the washing process using the venturi.
The venturi creates a vacuum by sucking in air, so the air can be exchanged from the vacuum flask and bubbled into the reactor at the same time.
