Abstract
Benzene is removed from carboxy polymethylene resin by dissolving the resin to form a solution and dispersing the solution as fine droplets in a gas phase or aerating the solution to introducing into it a fine dispersion of gas bubbles. The benzene transfer from the solvated resin to the gas phase and a benzene-free resin or solution can be obtained which may be usable in pharmaceutical and food products.
