Abstract
The present invention provides an improved method for preparing, purifying, precipitating, etc., a subject compound for use in a subsequent reaction carried out in suspension. The present invention relies on a precipitating solvent being added to an aqueous solution comprising the subject compound to form a precipitate of the subject compound, which may be further dried and/or purified. Compositions made according to present methods have improved characteristics and properties, such as increased surface and/or reduced density, resulting in a higher reactivity in a subsequent reaction carried out in suspension.

A method, comprising the following steps:
- (a) dissolving a starting form of a subject compound into an aqueous solvent to form an aqueous solution;
- and
- (b) adding a precipitating solvent to the aqueous solution to form a precipitate of the subject compound,
- wherein step (b) is performed after step (a), wherein the precipitating solvent is miscible in the aqueous solvent, and wherein the precipitate of the subject compound has a surface area per unit of mass that is greater than the surface area per unit of mass of the starting form of the subject compound.
A method, comprising the following steps:
- (a) providing an aqueous solution comprising an aqueous solvent and a subject compound dissolved therein;
- and
- (b) adding a precipitating solvent to the aqueous solution to form a precipitate of the subject compound,
- wherein step (b) is performed after step (a), wherein the precipitating solvent is miscible in the aqueous solvent, and wherein the precipitate of the subject compound has a surface area per unit of mass that is about 5 m2/gram or greater.
