Make Methanol from Methyl Esters + NaOh ? (Base Catalyzed Hydrolysis of Esters)
The Methanol was made by an base catalysed ester hydrolysis of methyl-benzoate. The other product is benzoic acid.
source: https://www.youtube.com/watch?v=GJMGzIQE4RM
Add to a Flask:
250ml water
40g Sodium Hydroxide (1mol Naoh)
Reflux, weight out 1 Mol of any Methyl-Ester and add it
slowly with additional funnel to the main flask.
Once reaction is finished, let cool and simple distill anything that boils under 100C
methanol boils at 64,7 °C.
Sodium Benzoate forms as byproduct, in main flask. is dissolved in water.
Question:
since any methyl ester can be used, why not use
Methyl acetate mol 74,08g/mol density 0,93g/cm3, 1 Liter = 930g and 12.55 mol
instead of
Methyl Benzoate, 136.15 g/mol, density: 1,08 g/cm³ 1 liter = 1080g and 7.93 mol
since 1 mol of any methyl ester will yield 1 mol of methanol,
using 1 unit of Methyl acetate
would give me almost 2x the yield and is cheaper to buy then
using 1 unit of Methyl Benzoate as seen in the video.
*byproduct of Methyl acetate would be Sodium acetate, instead of Sodium Benzoate.
did I make an error?

No. Methyl acetate should be easy to hydrolyze.

my calculation about almost 2x the yield by volume is also correct if using
Methyl acetate
instead of
Methyl Benzoate

It works, but why would you want to do this?

cause you can not get methanol anywhere here and its needed.
is there any other easier, higher yielding method out there to make methanol?
