Method of Preparing a Lubricant for Cold Working of Metals

摘要

The patent describes obtaining a lubricant for cold working of metals with saponification of synthetic fatty acids. It is distinguished by the fact that in order to improve the effectiveness of lubrication, synthetic fatty acids of a given fraction are subjected to saponification by a solid caustic at 150-200 degrees centigrade; the obtained product is held at 300-320 degrees centigrade up to total saponification and complete removal of traces of moisture. The product is subsequently cooled. (Author)
