| 摘 要：工業(yè)品5，5'-聯(lián)四唑-1，1'-二氧羥銨鹽（TKX-50）的晶體尺寸較小，形貌不規則，直接影響TKX-50的廣泛使用。針對TKX-50為羥胺鹽的特性，實(shí)驗選擇了水熱法對TKX-50進(jìn)行重結晶，結果表明：水熱法制備工藝簡(jiǎn)單，受外界條件影響小，制得的TKX-50晶體形貌較為統一規整，為菱形塊狀晶體；通過(guò)改變工藝條件還能夠實(shí)現對晶體尺寸的可控。升溫速率25℃·h-1，保溫時(shí)間0.5 h，降溫速率5℃·h-1時(shí)，制得的TKX-50晶體尺寸為0.3~0.4 mm；升溫速率為25℃·h-1，保溫時(shí)間2 h，降溫速率為3℃·h-1時(shí)，制得的TKX-50晶體平均尺寸為2.454 6 mm，最大晶體尺寸可達3.5 mm，通過(guò)水熱法對TKX-50重結晶的收率為68%。 |

| Abstract：The application of dihydroxylammonium 5,5-bistetrazole-1,1-diolate (TKX-50) in industry is directly affected by its crystal size and morphology. Our experiment chose hydrothermal method to recrystallize TKX-50 based on the characteristics of TKX-50. The result showed that the hydrothermal method required less steps and was less dependent on the external conditions. The crystal morphology of TKX-50 was uniform and regular, and it was a diamond block crystal. Changing the process conditions could subsequently change the crystal size. When the heating rate was 25℃·h-1, the holding time was 0.5 h, and the cooling rate was 5℃·h-1, the size of the TKX-50 crystal was 0.3~0.4 mm. When the heating rate was 25℃·h-1, the holding time was 2 h, and the cooling rate was 3℃·h-1, the average size of TKX-50 crystal was 2.5 mm with a maximum up to 3.5 mm. The final yield of recrystallization of TKX-50 by hydrothermal method was of 68%. |
