Title: David J Vanderah: Innovator in Explosive Formulations
Introduction
David J Vanderah is a notable inventor based in Ridgecrest, CA (US). He has made significant contributions to the field of explosive formulations, holding 2 patents to his name. His work focuses on the synthesis of advanced materials that enhance the performance of explosives.
Latest Patents
One of Vanderah's latest patents involves the synthesis of 5,7-diamino-4,6-dinitrobenzofuroxan. This compound is synthesized in high yield by the amination of 7-amino-4,6-dinitrobenzofuroxan with hydroxylamine in the presence of a strong base such as potassium hydroxide. The process includes acidification of the potassium salt, which produces a fine powder. Recrystallization of this powder through an extraction process under vacuum in solvents like dimethylformamide results in large, cube-like crystals. These crystals can be pressed into high-density explosive formulations, which demonstrate high performance as explosives.
