API Synthesis in a Batch Reactor Production of Benzoic .

API Synthesis in a Batch Reactor Production of Benzoic .

producing it is esterification[8]. Making benzoic acid from ethyl benzoate is a model reaction that shows how some API's are made using a batch reactor. Motivation for the study of this second order reaction and its rate constant is that without API's many diseases such as heart disease would be incurable[8].
