Abstract
A process for producing organic acid esters using continuous countercurrent reactive distillation using acid catalysts in a structured packing in a single column () is described. In the reactive distillation an organic acid ester is formed by chemical reaction and can be purified to its final state within the single column. Organic acid esters are produced at relatively low cost, with less waste production, and in a less complicated manner than prior processes. Organic acid ester have uses as solvents, as intermediate chemicals, and in consumer products.
