| THERMAL CATALYTIC SYNTHESIS OF KrF2 AND XeF2, AND THE APPLICATION OF KrF2 IN THE SYNTHESISOF FLUORO-CONTAINING INORGANIC HIGH ENERGY OXIDIZER NF4BF4 |

| 摘要: 本文介绍了一种以氟气和惰性气体为原料合成KrF2和XeF2的热催化合成方法并对合成机理和条件作了简单的讨论,利用合成的KrF2作为氟化剂合成了含氟高能氧化剂NF4BF4,纯度约为93%,其红外光谱和拉曼光谱基本与文献值吻合。元素分析结果表明产品NF4BF4中含B5.8%(mass),自由氟原子含量为9.95%(mass),与理论值基本一致,此结果也间接证明了KrF2质量的可靠性。粉末状的XeF2经升华-再结晶纯化后可得纯净晶体产品。 |

| Abstract: The noble gas binary fluorides KrF2 and XeF2 were synthesized in large quantity using a thermal-catalyticmethod,and the reaction mechanism and the operation conditions were discussed. The fluoro-containing inorganic high energy oxidizers NF4BF4 was synthesized in anhydrous HF solution using KrF2 as the fluoronating agentwith a purity of 93%.The IR and Raman spectra of the products were in good agreementwith those reported.The boron content in the NF4BF4 productdetermined by ICP-AES is 5.8% (mass),and the F- produced by the fast hydrolysis was determined,and it was found that the active fluorine content of the product in the hydrolysis reaction is only 9.95 % (mass). The results,which conformed to the theoretical data,confirmed indirectly thatthe quality of KrF2 is highly reliable. The pure XeF2 is colorless crystal,which can be obtained by sublimation-recrystallization process. |
