Tetranitrooxanilide was prepd by A.G. Perkin and used as a component of BkPdr type expls and of pyrotechnic compns (Ref 70, pp 331-34) (See also Hexanitrooxanilide)... 

Iowa (Ref 28) reported static electricity developed during LA handling. Monte si (Ref 31) described a fixed gap electrostatic discharge apparatus for characterizing expls. Perkins of PicArsn (Ref 32) gave a survey of methods of testing for electrostatic sensitivity of expls, while Gentner (Ref 33) described a test for Comp B. Satyavratan ...
