摘　　要：２，４，６，８，１０，１２－六硝基－２，４，６，８，１０，１２－六氮杂异伍兹烷（ＨＮＩＷ）作为目前威力最大的单质炸药，日益受到各国国防和航空工业的重视［１，２］．ＨＮＩＷ的合成，大体上分为缩合、催化氢解和硝化三步．在原料２，４，６，８，１０，１２－六...Nanoscale Pd(OH)2 was prepared by azeotropic distillation process for the first time, and its structure was characterized by high resolution TEM, DLS and UVVis absorption spectrum. The results show that the particle size of the prepared Pd(OH)2 is of 37.3 nm and the particles are facecentred cubic polycrystalline. The prepared Pd(OH)2 nanosized particles show a higher catalytic activity than 20% Pd(OH)2/C in the catalytic hydrogenolysis of 2,4,6,8,10,12hexabenzyl2,4,6,8,10,12hexaazaisowurtztane(HBIW).
