Taw qhia
Cov kuab tshuaj liab 1, tseem hu ua ketoamine liab lossis ketohydrazine liab, yog cov organic compound liab. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm cov kuab tshuaj liab 1:
Khoom: Nws yog cov hmoov nplej nrog cov xim liab ci, soluble hauv qee cov organic solvents xws li ethanol thiab acetone, tab sis insoluble hauv dej. Nws pom zoo stability nyob rau hauv ob qho tib si acidic thiab alkaline tej yam kev mob.
Siv:
Cov kuab tshuaj liab 1 feem ntau yog siv los ua cov cim tshuaj, uas tuaj yeem siv rau hauv kev sim tshuaj xws li acid-base titration thiab kev txiav txim siab hlau ion. Nws tuaj yeem tshwm daj hauv cov kua qaub thiab liab hauv cov tshuaj alkaline, thiab pH ntawm cov tshuaj tuaj yeem qhia tau los ntawm kev hloov xim.
Txoj kev:
Txoj kev npaj ntawm cov kuab tshuaj liab 1 yog qhov yooj yim, thiab nws feem ntau yog tsim los ntawm cov tshuaj tiv thaiv condensation ntawm nitroaniline thiab p-aminobenzophenone. Cov txheej txheem synthesis tshwj xeeb tuaj yeem nqa tawm hauv chav kuaj.
Cov ntaub ntawv kev nyab xeeb:
Solvent Red 1 kuj muaj kev nyab xeeb nyob rau hauv ib txwm ua haujlwm, tab sis cov hauv qab no yuav tsum tau sau tseg:
3. Tsis txhob kov cov oxidants thiab cov kua qaub uas muaj zog thaum khaws cia.
4. Thaum siv, hnav cov hnab looj tes tiv thaiv thiab tsom iav kom ntseeg tau tias kev ua haujlwm tau ua nyob rau hauv qhov chaw muaj cua zoo.
