In a finely dispersed emulsion of a water immiscible solution of an organic polyfunctional Lewis base and an aqueous solution of a partially hydrophilic, partially lipophilic polyfunctional Lewis acid, a reaction occurs at the phase interface to produce a novel microparticulate material comprised of the reaction product of the Lewis acid and the Lewis base. The maximum particle size dimensions of the microparticulate material depends on the degree of dispersion in the emulsified reaction mixture and may be as low as 2 microns or smaller. |
