APPARATUS FOR EVALUATING CARBONATE SOLUBILITY

摘要

A method and apparatus of determining solubility of compounds at non-ambient conditions is disclosed. The compound of interest is placed in a reaction vessel which can withstand the non-ambient conditions, and is allowed to react with an acid at those conditions for a pre-determined time. The reaction is quickened thereby stopping the reaction, after which the conditions are permitted to return to ambient and the solubility of the compound is then determined gravimetrically.

1. A method for gravimetric determination of solubility of a compound at non-ambient conditions, comprising:
(a) combining said compound with an acid solution in a reaction vessel at conditions of temperature and pressure which are at non-ambient conditions, for a predetermined time in a reaction vessel; (b) adding a quenching solution to neutralize said acid solution; (c) displacing said acid solution and said quenching solution from said reaction vessel; (d) adding a washing solution to said reaction vessel; (e) removing said washing solution; (f) adjusting at least one of pressure and temperature in said reaction vessel to ambient conditions, wherein (a), (c), (d), (e), and (f) stop solubilization of said compound, and (g) gravimetrically determining solubility of said compound at said non-ambient conditions.
