Patent number: 8367877Abstract: Methods of purifying BT are disclosed. The method comprises adding at least one polyhydroxyl compound to a crude BT mixture comprising BT and at least one boron-containing compound to form a polyhydroxyl compound/BT mixture. In one embodiment, the polyhydroxyl compound/BT mixture is then heated to a temperature greater than the boiling point of BT but less than the boiling point of the at least one polyhydroxyl compound. In another embodiment, the polyhydroxyl compound/BT mixture is heated to a temperature greater than the melting point of the at least one polyhydroxyl compound, and then to a temperature greater than the boiling point of BT but less than the boiling point of the at least one polyhydroxyl compound. A composition comprising BT is also disclosed.Type: GrantFiled: November 17, 2009Date of Patent: February 5, 2013Assignee: Alliant Techsystems Inc.Inventors: Stephen P. Velarde, Andrew J. Sanderson

Patent number: 8030521Abstract: Methods of producing TATB are disclosed. The method comprises providing acid wet TNPG and distilling water from the acid wet TNPG. The TNPG is reacted with an alkoxylating agent to form a solution of 1,3,5-trialkoxy-2,4,6-trinitrobenzene solution, which is reacted with an aminating agent. An alternate method comprises nitrating phloroglucinol in a first vessel to produce TNPG, which is reacted with an alkoxylating agent in a second vessel to form a solution comprising 1,3,5-trialkoxy-2,4,6-trinitrobenzene and at least one of at least one volatile byproduct and at least one nonvolatile byproduct. The at least one of at least one volatile byproduct and at least one nonvolatile byproduct is removed in situ. The 1,3,5-trialkoxy-2,4,6-trinitrobenzene is reacted with an aminating agent.Type: GrantFiled: May 7, 2007Date of Patent: October 4, 2011Assignee: Alliant Techsystems Inc.Inventors: Stephen P.
