Taw qhia
5-Nitrobenzotriazole yog ib qho organic compound. Cov hauv qab no yog ib qho kev qhia txog qee yam ntawm cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm cov khoom sib xyaw no:
Zoo:
- Cov tsos mob: tsis muaj xim crystalline lossis yellowish khoom.
- Solubility: soluble hauv chloroform, dimethyl sulfoxide (DMSO), me ntsis soluble hauv ethanol, ether, yuav luag insoluble hauv dej.
Siv:
- Nws tseem tuaj yeem siv los ua cov khoom siv hauv cov khoom siv hluav taws xob electroluminescent (OLED) txhawm rau txhim kho kev ua haujlwm ntawm cov khoom siv hluav taws xob.
Txoj kev:
- Muaj ntau txoj kev npaj rau 5-nitrobenzotriazole, thiab ib qho ntawm cov kev siv feem ntau yog cov tshuaj tiv thaiv ntawm benzotriazole nrog nitric acid. Cov kauj ruam tshwj xeeb yog kom yaj benzotriazole hauv acetic acid, tom qab ntawd maj mam ntxiv cov nitric acid, cov tshuaj tiv thaiv kub yog tswj ntawm 0-5 ° C, thiab thaum kawg cov khoom tuaj yeem tau txais los ntawm kev pom thiab ziab.
Cov ntaub ntawv kev nyab xeeb:
- 5-nitrobenzotriazole yog tawg, thiab nws cov ntsev mercury kuj tsis ruaj khov.
- Kev ntsuas kev nyab xeeb nruj xws li kev ua haujlwm cryogenic, ntsuas kev tiv thaiv tawg thiab hnav cov khoom tiv thaiv tus kheej tsim nyog (xws li kuaj hnab looj tes, tsom iav kev nyab xeeb, thiab lwm yam) yuav tsum tau ua thaum ua haujlwm.
- Khaws cia kom deb ntawm qhov hluav taws kub, tshav ntuj ncaj qha, thiab nyob rau hauv lub thawv airtight thaum khaws cia thiab siv.
- Kev siv thiab tuav cov khoom sib txuas no yuav tsum tau ua nyob rau hauv ib puag ncig kev sim tsim nyog thiab cov txheej txheem kev khiav haujlwm yuav tsum tau ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab tiv thaiv ib puag ncig.
