DEVELOPMENT OF NONFLAMMABLE HYDRAULIC FLUIDS AND LUBRICANTS.
Abstract
The preparation and preliminary evaluation of a number of trimeric and tetrameric bis (alpha, alpha, omega -tri-H-polyfluoroalkyl) phosphonitrilates, mixed substituted trimeric and tetrameric (phenyl - alpha, alpha, omega-tri Hpolyfluoroalkyl) phosphonitrilates, and mixed substituted trimeric and tetrameric (substituted phenyl-alpha, alpha, omega-tri H-polyfluoroalkyl) phosphonitrilates is described. Many products have wide liquid ranges with pour points ranging down to -55 F. They also have high compression ignition ratios and relatively high spontaneous ignition temperatures. Good lubricity and compatibility to rubber are other favorable properties. In order to obtain hydrolytically stable products, new synthesis and purification methods were developed. The compounds are promising candidates for potential use as non-flammable hydraulic fluids and lubricants. (Author)
