溶剂对RDX热分解的影响

Effect of Solvents on Thermal Decomposition of RDX

用布氏压力计研究不同溶剂对溶液中RDX热分解的影响。影响分为加速、抑制和无影响三种情况 :在苯、萘、异辛烷中RDX热分解速率与熔融态一致 ,这类溶剂对RDX热分解无影响 ;脂肪族芳香化合物、醚、酯、酮及醇能加速RDX热分解 ;粘度较大的化合物则抑制RDX热分解。

Effect of different solvents on thermal decomposition of RDX was studied by using special Bourdon manometer. Solvents can accelerate,inhibit or do not affect decomposition of RDX: (1) inert solvents,such as benzene,naphthalene, isooctane, do not affect decomposition rate of RDX; decomposition rate in these solvents is the same as that in melt state; (2) solvents,like aliphatic aromatic compounds,alcohols,ketones,ethers and esters,increase decomposition rate of RDX; (3) solvents with large viscosity inhibit thermal decomposition of RDX.
