Reactive distillation for methyl acetate production
The production of methyl acetate is a classic example of successful reactive distillation technology (Agreda & Partin 1984; Agreda Partin & Heise 1990) Soon after the invention and commercial application of this tech-nology for methyl acetate synthesis it was used as a model system for testing a new design and synthesis

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?
- A test tube containing 12 ml of methyl acetate was set into a thermostat at 25oC. thermostat. After about 10-15 minutes, when thermal equilibrium is established, phenolphthalein as the indicator. Then 100 ml of the acid was transferred to each of reestablishment of thermal equilibrium. Precisely 5 ml of methyl acetate was
