Summary An acid regenerated cation exchange resin (Dowex‐50, 200–400 mesh) is an effective catalyst for tallow splitting. The optimum level of catalyst was approximately 3% of the weight of fat. A two‐stage operation for 12 hr. at 100°C. gave fatty acid yields which ranged from 96% to 100% (calculated as % oleic acid). The Dowex‐50 catalyst was easily recovered after each operation, regenerated with 100 ml. of 4N. hydrochloric acid, and used again in the next operation with no appreciable decrease in catalytic activity. The original resin can be used in continued efficient tallow splitting operations if the residual resin is regenerated after each complete operation and additional fresh resin is added to make up mechanical loss.
