1. Cov Qauv Molecular ntawm Adipic Acid Dihydrazide (ADH)
Cov qauv ntawm Adipic Acid Dihydrazide muaj xws li:
-
Adipic acid(ib qho kua qaub dicarboxylic rau-carbon, C₆H₁₀O₄) uas tau hloov kho los ntawm kev txuas ob pawg hydrazine (-NH-NH₂) rau cov pawg carboxyl ntawm cov kua qaub.
-
Cov qauv tshuaj ntawm ADH tuaj yeem sawv cev raws li:
HOOC-(CH₂)₄-CO-NH-NH₂
Nws yog dihydrazide, txhais tau tias txhua tus ntawm ob pawg carboxyl (-COOH) ntawm adipic acid yog khi rau ib pawg hydrazine (-NH-NH₂).
Cov qauv tsim muaj xws li lub hauv paus tseem ceebadipic acid qaum, nrog rau cov pab pawg ua haujlwm hydrazine ntawm txhua qhov kawg, ua rau ADH ua ib qho tshuaj reagent tseem ceeb hauv ntau yam tshuaj lom neeg.
2. Kev tsim cov Adipic Acid Dihydrazide
Feem ntau, kev tsim cov ADH yog los ntawm kev sib xyaw cov adipic acid nrog hydrazine hydrate. Cov kauj ruam rau kev tsim cov ADH no muaj raws li nram no:
-
Kev sib xyaw ntawm Adipic Acid nrog HydrazineAdipic acid raug tshuaj nrog ntau dhau ntawm hydrazine hydrate (NH₂-NH₂·H₂O) hauv cov kuab tshuaj tsim nyog (xws li ethanol lossis dej) nyob rau hauv cov xwm txheej tswj hwm (piv txwv li, kub siab).
-
Kev tsim ntawm DihydrazideCov pawg hydrazine txuas rau ob pawg carboxyl ntawm adipic acid, tsim Adipic Acid Dihydrazide.
-
Kev ntxuav kom huvCov khoom no ces raug ntxuav, feem ntau yog los ntawm kev rov ua dua tshiab, kom tshem tawm cov tshuaj reagents uas tsis tau ua haujlwm thiab tau txais ADH ntshiab.
Cov tshuaj tiv thaiv tuaj yeem sawv cev li:
HOOC-(CH₂)₄-COOH + 2 NH₂-NH₂ → HOOC-(CH₂)₄-CO-NH-NH₂ (ADH)
