Abstract
15,531. Arledter, H., and Whitney, R. J., [Arledter, F.]. Oct. 24. Resins and resinous compounds.-Relates to a process for purifying and decolorizing commercial resins, fats, and oils. The resin or other material is heated under pressure, and at a high temperature, in presence of a suitable alkali, water, and carbonic-acid gas. The mixture is then allowed to cool and the purified resin is separated from the lye. If desired, sulphurous-acid gas may be passed into the solution to bleach the resin or oil.
