What is the hydrolysis of methyl acetate?

The hydrolysis of methyl acetate presents a number of interesting kinetic aspects. The reaction, which is extremely slow in pure water, is catalyzed by hydrogen ion. Hydrolysis is a reaction involving the breaking of a bond in a molecule using water. The hydrolysis of methyl acetate produces acetic acid and methanol. The reaction is:

What is the reaction of methyl acetate to acetic acid and methanol?

1. INTRODUCTION Hydrolysis of methyl acetate (MeOAc) to acetic acid and methanol is one of the major reactions since a great deal of methyl acetate is produced as by-product during the synthesis of polyvinyl alcohol (PVA) and pure terephthalic acid (PTA). It is estimated that 1.5-1.7 tons of MeOAc is produced per ton of PVA [1, 2].

What is the molar ratio of water to methyl acetate?

The molar ratios of water to methyl acetate should be in the range of about from 0.5 to 10.0, and preferably about from 1.0 to 4.5. The feed mixture can also contain up to about 20 wt. % of methanol, 15 wt. % acetic acid, and 1-2 wt. % acetaldehyde.

How to determine thermal equilibrium of methyl acetate?
