Taw qhia
2-nitrophenylhydrazine hydrochloride. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos mob: Dawb crystalline lossis crystalline hmoov.
- Solubility: soluble hauv dej, me ntsis soluble hauv cawv thiab ethers.
- Cov khoom siv tshuaj: kev ruaj ntseg zoo, tuaj yeem muaj qee cov tshuaj tiv thaiv organic nrog rau lwm cov tebchaw.
Siv:
- 2-Nitrophenylhydrazine hydrochloride feem ntau yog siv rau hauv kev sib xyaw ntawm cov tshuaj tua kab thiab kev npaj cov khoom tawg.
- Nws tuaj yeem siv los ua ib qho nruab nrab ntawm cov tshuaj tua kab timmodine thiab ua tus thawj coj ntawm kev npaj tawg hexanitroglutarate.
Txoj kev:
2-Nitrophenylhydrazine hydrochloride tuaj yeem npaj los ntawm cov kauj ruam hauv qab no:
1. 2-nitrophenylhydrazine reacts nrog hydrochloric acid los ua 2-nitrophenylhydrazine hydrochloride.
2. Lub hom phiaj khoom yog tau los ntawm crystallization, pom thiab ziab.
Cov ntaub ntawv kev nyab xeeb:
- 2-Nitrophenylhydrazine hydrochloride yog qhov ruaj khov nyob rau hauv ib txwm ua haujlwm, tab sis tsim kom muaj kev phom sij tawg nyob rau hauv qhov kub thiab txias, lasers, lossis lwm qhov chaw kub.
- Hnav cov cuab yeej tiv thaiv tsim nyog xws li hnab looj tes (lab) hnab looj tes, tsom iav, thiab lub tsho (lab) thaum ua haujlwm.
- Tsis txhob sib cuag nrog cov acids muaj zog, muaj zog oxidants, thiab lwm yam.
- Tsis txhob nqus cov plua plav lossis kev sib cuag ntawm daim tawv nqaij kom tsis txhob ua xua lossis ua xua.
- Nws yuav tsum tau ua nyob rau hauv ib qho chaw zoo-ventilated kuaj kom tsis txhob nqus nws vapors. Yog tias nqus tau, txav mus rau huab cua ntshiab thiab nrhiav kev kho mob.
