Study on Synthesis of N-Nitroborazine Compounds. 2. Borazine Derivatives

Pagination or Media Count:
Attempts to synthesize borazine derivatives for use in propellants and related tems are described. Borazine itself was unsuitable as starting material since it has a tendency to polymerize andor decompose at room temperature however, B-trimethylborazine is extremely stable from decomposition or attack from air or moisture. Borazine reacted violently with nitryl chloride in the absence of diluent. In solution, the reaction was moderated by vigorous and the borazine appeared to have been completely oxidized. Synthesis and isolation of B-trimethylborazine from B-trichloroborazine and methyl lithium or methyl magnesium chloride proved to be extremely tedious. In addition the yields were much lower than expected. Conditions were varied but yields did not improve. The regeneration of borazine from its solid complex with hydrogen chloride was investigated in order to devise a convient method for its storage.
