Esterification of glycerol with acetic acid over dodecamolybdophosphoric acid encaged in USY zeolite

Catalytic Esterification of Acetic Acid with Methanol; Comparison of Photocatalytic and Acid Catalysed Esterification

Methyl acetate is produced through catalytic esterification of acetic acid with methanol. Catalytic acceleration is induced by sulfuric acid or ion exchange resins respectively. Acceptable product yield is obtained by reactive distillation. Separation and isolation of methyl acetate has to overcome two azeotropes (methyl acetate – water and methyl acetate methanol). Scope of this project has be...

Esterification of Glycerol with Acetic Acid over Highly Active and Stable Alumina-based Catalysts: A Reaction Kinetics Study

Recently, biomass-derived energy has been receiving more and more attention due to the depletion of conventional fossil sources at a faster rate, as well as major environmental issues.1 Biodiesel obtained by transesterification of vegetable oils and animal fats provides an alternative fuel option for the future.2 Transesterification of oils and animal fats produce glycerol in large excess (10 k...

Vapor Phase Esterification over Sodium Acid Sulfate

Esterification of Acetic Acid with Butanol: Operation in a Packed Bed Reactive Distillation Column

The esterification reaction between acetic acid and butanol was investigated in a reactive distillation column. The thermodynamic aspects of considered system are discussed, equilibrium constant, vapor pressures and UNIQUAC interaction parameters were investigated. Reactive distillation experiments were carried out to provide high purity butyl acetate. For this purpose, a 2 m column with nonrea...

Kinetics of Esterification of Ethylene Glycol with Acetic Acid Using Cation Exchange Resin Catalyst

The esterification of ethylene glycol with acetic acid was investigated in a batch reactor in presence of a strongly acidic cation exchange resin, seralite SRC-120, as catalyst in the temperature range of 333 to 363 K. The detailed kinetic study was performed to understand the effect of various process variables such as catalyst loading, ethylene glycol to acetic acid mole ratio, and temperatur...
