Synthesis of Benzocaine

A. Introduction/Aims: The aim of the current investigation is to investigate the acid-catalysed Fischer esterification mechanism underlying the synthesis of the anaesthetic benzocaine using p-aminobenzoic acid and ethanol in excess. The resulting synthesised compound was subject to IR and melting point analyses in order to determine the identity and indeed the purity of the obtained […]

Experiment to investigate the heat of combustion of alcohols

Introduction The heat of combustion of alcohols is the change in kJ/mol when 1 mole of the alcohol is burnt in excess oxygen (O2). I will be investigating 6 alcohols, using predictions and a practical to guide me through this experiment and form an overall conclusion. Using formulas and calculations, I can show how much […]
