    摘要: In the process of manufacturing a refrigeration oil where an oil stock is dewaxed by forming a complex with urea in the presence of an activator, the improvement of adding hot vacuum gas oil to the separated urea complex whereby the activator is flashed off and is recycled for reuse and the slurry of the urea complex in the gas oil is treated with hot water to break the adduct and separate a water-urea mixture and oil and paraffin. The improved method enables accurate and uniform temperature control and degradation of urea is suppressed.
