| 摘 要： | 研究了常压下以Pd/C为催化剂由四乙酰基二苄基六氮杂异伍兹烷(TADB)氢解脱苄合成四乙酰基六氮杂异伍兹烷(TAIW)的反应动力学。结果表明,在本实验条件下从反应开始到反应完成约90%时(以吸氢量计)TADB氢解脱苄对于TADB为一级反应。当反应介质为乙酸混合溶液时,常压氢气下该反应表观活化能为45.63kJ·mol-1,指前因子为106.04min-1;反应介质换为冰乙酸时反应表观活化能增大到79.90kJ·mol-1,指前因子则为109.93min-1。

| Abstract: | The reaction kinetics of synthesis of tetraacetylhexaazaisowurtzitane (TAIW) by hydrogenolysis debenzylation of tetraacetyldibenzylhexaazaisowurtzitane (TADB) was investigated,using Pd/C as catalyst in an atmosphere of hydrogen. Results show that the reaction is the first-order to TADB during the stage from the beginning to the moment when about 90% H2 is absorbed under the experimental conditions. When the solvent is acetic acid mixture,the apparent activation energy and pre-exponential factor of this reaction are 45.63 kJ·mol-1 and 106.04 min-1,respectively. While for acetic acid,they are 79.90 kJ·mol-1 and 109.93 min-1,respectively. |
