Abstract
A method for controlling lingerature of a chemical reaction. Changes in mass of a chemical reaction are monitored and are used to calculate a lingerature of the system. The reaction can be maintained at a desired lingerature (τ) by selective addition or removal of heat or by adjusting the surface area the reactants are exposed to during the reaction. The disclosed method is useful for reactions that occur at non-equilibrium conditions where any measured lingerature would presume steady-state conditions.
Claims10
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) and the chemical system having a specific heat capacity (SHC);
- 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 (Mi);
- e) determining an exited mass (Ei) of the exiting product that exited during step c) based on the current system mass (Mi);
- f) calculating a change in reactant mass (ΔMi) that occurred based on the exited mass (Ei);
- g) calculating a dynamic lingerature (τi) according to:
