Title: Joseph A. Neff: Innovator in Chemical Compounds
Introduction
Joseph A. Neff is a notable inventor based in San Clemente, California. He has made significant contributions to the field of chemistry, particularly in the synthesis of new chemical compounds. With a total of 2 patents to his name, Neff's work showcases his innovative approach to chemical research.
Latest Patents
Neff's latest patents include the development of Tris-tetrafluorammonium hexafluoraluminate and its method of preparation. This new compound, represented as (NF.sub.4).sub.3 AlF.sub.6, is synthesized by mixing solid aluminum trichloride in a solution of a molar excess of tetrafluorammonium bifluoride in anhydrous hydrogen fluoride at a temperature of about -78 degrees Celsius or lower. The mixture is then rapidly heated to approximately 40 degrees Celsius, reaching the decomposition temperature of the product until all solids dissolve. The resulting solution is evaporated under vacuum conditions, leading to the crystallization of (NF.sub.4).sub.3 AlF.sub.6. Another significant patent involves the production of tetrafluorammonium bifluoride and tetrafluorammonium. In this process, the compound NF.sub.4 MF.sub.6, where M is a Group V metalloid, is reacted with a sodium fluoride to yield tetrafluorammonium bifluoride in solution with hydrogen fluoride, along with a precipitate of the formula NaMF.sub.6. The preferred metalloid for this reaction is antimony, and the formed tetrafluorammonium bifluoride can be converted to NF.sub.4 BF.sub.4 by reacting with BF.sub.3.
