Use of complex agents in crystal formation reactions in the complex system

摘要

Methods and reaction systems are disclosed that are adapted for forming crystallites having novel crystal habits and/or morphologies compared to conventional crystallites of the same chemical composition. The methods and reaction systems involve chemical reactions between at least two reactant compounds occurring in a liquid (or gel) that form insoluble crystallite products. At least one of the reactants is rendered soluble in a solvent in which the reactant is not normally soluble by adding an agent that forms soluble molecular complexes of the agent and the reactant. The complexing agent not only facilitates dissolution of the reactant in the solvent but also plays a role in how the faces of crystals comprising the crystallite product are enlarged during formation of the product. Products having such altered crystallite structure have a number of possible uses.
