Taw qhia
Diethyl zinc yog ib qho organozinc compound. Nws yog cov kua uas tsis muaj xim, flammable thiab muaj ntxhiab tsw. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm diethylzinc:
Zoo:
Cov tsos mob: Cov kua xim tsis muaj xim nrog pungent tsw
Ceev: approx. 1.184 g / cm³
Solubility: soluble hauv cov kuab tshuaj organic xws li ethanol thiab benzene
Siv:
Diethyl zinc yog ib qho tseem ceeb reagent nyob rau hauv cov organic synthesis thiab yog siv nyob rau hauv kev npaj ntawm catalysts.
Nws kuj tseem siv tau los ua inducer thiab txo tus neeg sawv cev rau olefins.
Txoj kev:
Los ntawm reacting zinc hmoov nrog ethyl chloride, diethyl zinc yog generated.
Cov txheej txheem kev npaj yuav tsum tau ua nyob rau hauv kev tiv thaiv ntawm ib qho inert roj (xws li nitrogen) thiab nyob rau hauv qis kub kom ntseeg tau tias muaj kev nyab xeeb thiab siab yield ntawm cov tshuaj tiv thaiv.
Cov ntaub ntawv kev nyab xeeb:
Diethyl zinc yog cov nplaim hluav taws kub heev thiab kev sib cuag nrog lub qhov hluav taws xob tuaj yeem ua rau hluav taws kub lossis tawg. Kev tiv thaiv hluav taws thiab tawg yuav tsum tau ua thaum khaws cia thiab siv.
Hnav cov khoom tiv thaiv tsim nyog xws li khaub ncaws tiv thaiv tshuaj, tsom iav tiv thaiv, thiab hnab looj tes thaum siv.
Tsis txhob sib cuag nrog cov oxidants muaj zog thiab cov kua qaub kom tiv thaiv kev ua phem.
Diethylzinc yuav tsum tau ua nyob rau hauv ib qho chaw zoo-ventilated los txo cov tsub zuj zuj ntawm cov pa phem.
Khaws kaw kom nruj thiab muab tso rau hauv qhov chaw qhuav, txias kom tsis txhob muaj kev ntxhov siab.
