Abstract
A computerized compound synthesization for producing an aimed product by controlling a synthesis reaction process including steps of supplying raw material compounds, reagents and solvents, a synthesis reaction step, a purification step and a product extraction step in accordance with a control program. Optimal condition for the reaction is established by determining discrete time points at which the reagent is added and volumes of the reagent to be added at the time points, respectively, on the basis of parameters including reaction rate constant, equilibrium, constant, initial concentration of starting material mixture, ratio of concentration of intermediate product to theoretical equilibrium concentration, stoichiometrical ratio between the reagent and the intermediate and concentration of the reagent in accordance with a relation established among these parameters.
