    摘要： A process for separating phthalimido-peroxycaproic acid (PAP) from solutions in organic solvents, wherein the organic solvents have a solubility in water equal to or lower to 10% by weight, is provided. The process employs the following steps:(a) dispersing the solution in an aqueous medium to form a suspension;(b) bubbling an inert gas into the resulting suspension; and(c) recovering PAP from the suspension.
