2660.     PEUSEL, -----.  Lubricants and Surface Protection in the Metal Industry.  TOM Reel 53, February 1945, frames 62-95.

        Discusses some important developments in the field of lubricants.  The starting material is Kogasin, obtained as a product of the Fischer-Tropsch synthesis and hydrogenated into Mepasin.  It was found that a derivative of this, Mepasin sulfonamido acetic acid, had outstanding qualities as a lubricant in metal working, both for cutting, drilling, and milling and for hot and cold shaping, deep drawing of wire, etc.  The product is used as an emulsion, both because the lubricating effect is not affected and savings are made, and because this greatly reduced the danger of plant fires.  There is presented during the discussion what appears to be a relatively new theory of film formation, lubricating effect, and adhesion to metal.  The theory involves molecular polarity, formation of supermolecular structures in the nature of liquid colloidal crystals, the interplay of surface forces, and other novel hypotheses that appear to be solidly grounded and highly illuminating.  It is claimed that the new Mepasin derivatives actually make pretreatment of metal blanks in deep-drawing operations unnecessary.
