Semicontinuous distillation of impurities for the production of butyl acrylate from bio-butanol and bio-acrylic acid

Chemical production processes which use biosynthetic pathways typically experience variations in the concentration and composition of impurities contained in the products, due to the natural variability of biological behaviour. As a result, downstream processes which use these biosynthetic chemical products need to be quite flexible with respect to the impurity concentrations. In this study, a ternary semicontinuous distillation process is …
