Abstract: A process for the preparation of anhydrous high purity phosphorus pentafluoride in high yield. The process uses an excess of hydrogen fluoride in a reaction with a phosphoric acid to form hexafluorophosphoric acid followed by reaction with a sulfur based acid reactant in a reaction medium containing an excess of hydrogen fluoride.

Abstract: The invention provides a process, and product thereof, for forming a chemically resistant fusion bonded between chemically dissimilar materials by use of an acid-based terpolymer for protective garments. The olefin terpolymers are preferably copolymers of an olefin, an acid and an ester. The process involves placing the olefin terpolymer film between two dissimilar films such as a facepiece and the fabric material of the garments and applying heat and pressure. The resulting fusion bonded film composite is strong, flexible and upon the application of sufficient stress exhibits total cohesive rupture failure.

Abstract: A sealed pouch of a single layer polyolefin film having a thickness of from about 0.005 to 0.001 inch and a melting point below about 280.degree. F. which is soluble in a lubricating oil base. The pouch contains a solid lithium hydroxide or lithium fatty acid salt or mixtures thereof for use in preparing greases.

Abstract: The present invention provides a method for forming dust free lithium hydroxide monohydrate. The method contains the step of coating the lithium hydroxide with 0.1 to 5% by weight of low melting or liquid fatty acids or esters and triglycerides of fatty acids.
