Abstract

The objective of this work is to use a robotic workstation in conjunction with process systems analysis tools to enhance process development. A case study using an L-proline catalysed aldol reaction is used to demonstrate that, in conjunction with appropriate experimental designs, meaningful data streams for mechanistic / kinetic studies can be generated. It is shown that for this system small scale (13ml) reactors in a robotic high throughput platform may be used for (1) initial screening of potential solvents through assessment of the solubility and miscibility characteristics of the reactants and catalyst (2) determination of the concentrations of reactants and catalyst that maximise the production of aldol. To assess reaction thermo chemistry and at the same time generate data suitable for detailed mechanistic modelling a large scale (1 litre) calorimeter is used. The experimental data allowed a novel reaction network for the L-proline catalysed aldol reaction to be proposed and verified through a kinetic modelling exercise.
