Chemists can use a variety of methods and intuition to analyse the reaction mixture to predict progression at the current instant in time or the future progression. For example, it may be determined a reaction has plateaued if two measurements in succession show no change in the reaction profile. Alternatively, a chemist may have experience with the reaction and develop an empirically based intuition of when the reaction has ended. For example, a reaction may typically reach completion at a variable conversion but within the same timeframe. The research here aims to test the suitability of machine learning for this objective.
