5-Chloro-3-nitropyridine-2-carbonitrile (CAS # 181123-11-5) Taw qhia
-Zoo: Lub teeb daj mus rau daj siv lead ua.
- Melting point: Melting point yog hais txog 119-121 ° C.
-Solubility: Soluble nyob rau hauv cov organic solvents xws li methanol, chloroform thiab dichloromethane.
Siv:
- feem ntau yog siv los ua ib qho nruab nrab hauv cov organic synthesis rau kev sib txuas ntawm lwm cov organic sib txuas.
-Nws tuaj yeem siv los npaj tshuaj, tshuaj tua kab thiab khoom siv hluav taws xob.
Txoj kev: Kev npaj ntawm
-phosphonate tuaj yeem tau los ntawm reacting 2-cyano-5-chloropyridine nrog sulfuryl chloride thiab sodium nitrite nyob rau hauv lub xub ntiag ntawm lub hauv paus.
Cov ntaub ntawv kev nyab xeeb:
-Cov txheej txheem hauv kev siv thiab kev khaws cia yuav tsum tau ceev faj kom tsis txhob muaj kev sib cuag nrog cov oxidants muaj zog, muaj zog acids lossis muaj zog alkali thiab lwm yam tshuaj tiv thaiv kom tsis txhob muaj kev phom sij txaus ntshai.
- Hnav cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes (lab), tsom iav thiab tiv thaiv lub ntsej muag thaum ua haujlwm.
-Tsis txhob nqus, zom lossis nqos cov tshuaj no. Thaum muaj kev sib chwv tsis sib haum, yaug tam sim nrog dej ntau thiab nrhiav kev pab kho mob.
