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...
متن کاملEsterification of phenyl acetic acid with p-cresol using metal cation exchanged montmorillonite nanoclay catalysts
The liquid phase esterification of phenyl acetic acid with p-cresol over different metal cation exchanged montmorillonite nanoclays yields p-cresyl phenyl acetate. Different metal cation exchanged montmorillonite nanoclays (M n+ = Al3+, Zn2+, Mn2+, Fe3+, Cu2+) were prepared and the catalytic activity was studied. The esterification reaction was conducted by varying molar ratio of the reactants,...
متن کاملKinetic Study of the Heterogeneous Catalytic Esterification of Acetic Acid with Methanol Using Amberlyst®15
The bulk chemicals esters contribute to commodity chemicals in nearly unlimited variety. Common fields of application include their use as solvents, plasticizers, surfactants, flavours, inter mediates in preparative organic chemistry, and many more.1 Though well investigated, the technology of ester production offers some challenging characteristics regarding catalysis, operation conditions and...
متن کاملPreparation of a novel poly(vinylsulfonic acid)-grafted solid phase acid catalyst and its use in esterification reactions.
A high-density sulfonic acid polymer, grafted onto a carrier surface, was synthesized from the acid form of vinylsulfonic acid monomer, and its catalytic activity as a new class of heterogeneous acid catalyst demonstrated in esterification reactions.
