Title: Innovations of Xiao-Pei Guan

Introduction

Xiao-Pei Guan is an accomplished inventor based in Malden, MA (US). He holds 2 patents that contribute significantly to the field of chemical compounds, particularly in the area of explosives and propellant oxidizers.

Latest Patents

His latest patents focus on geminal-dinitro-1,5-diazocine derivatives. This invention introduces a new class of compounds, specifically certain geminal-dinitro-substituted heterocycles, including geminal-bis(difluoramino)-substituted heterocyclic nitramines. The production of 3,3-bis(difluoramino)octahydro-1,5,7,7-tetranitro-1,5-diazocine (TNFX) is a key aspect of this invention. TNFX can be formulated into explosives and propellant oxidizers. The method of creating this compound involves reacting a hexahydro-7,7-dinitro-1,5-bis(nitrobenzenesulfonyl)-1,5-diazocin-3(2H)-one with a difluoramine source. This reaction produces a 3,3-bis(difluoramino)octahydro-7,7-dinitro-1,5-bis(nitrobenzenesulfonyl)-1,5-diazocine. Subsequently, this compound is reacted with a highly reactive nitrating reagent in the presence of a strong Lewis acid, such as antimony pentafluoride, boron triflate, or boron fluorosulfonate.
