5 Claims

1. A method for controlling lingerature of a chemical reaction, the method comprising steps of:

a) determining an initial system mass (M) of a chemical system which performs a chemical reaction between reactants in a solvent to produce products, wherein at least one of the products is an exiting product that is a gaseous product or a precipitation product, the chemical reaction having a desired temperature (T), a desired lingerature (τ);

b) adding the reactants and the solvent to a vessel, thereby initiating the chemical reaction;

c) allowing the exiting product to exit the vessel;

d) measuring a current system mass (M_i);

e) determining an exited mass (E_i) of the exiting product that exited during step c) based on the current system mass (M_i);

f) calculating a change in reactant mass (ΔM_i) that occurred based on the exited mass (E_i);

g) adjusting a surface area experienced by the reactants by adding or removing an insoluble mass to the vessel in an amount to provide a change in the surface area (ΔA_i) according to:

if the chemical reaction is an exothermic reaction or according to:

if the chemical reaction is an endothermic reaction, wherein β is a number between 0.8 and 1.2,

h) adding a soluble mass in an amount sufficient to restore the initial system mass (M), the amount of the soluble mass determined based on the exited mass (E_i) and the insoluble mass; and

i) iteratively repeating steps c) to h).
