Taw qhia
Lub octalal diacetal. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm octanal diethylacetal:
Zoo:
Octanal diacetal yog cov kua tsis muaj xim nrog cov yam ntxwv aroma ntawm aldehydes. Nws yog cov kua roj tsis hloov pauv nrog qhov ceev ntawm 0.93 g / cm3 ntawm chav tsev kub. Nws yog soluble hauv cov kuab tshuaj organic xws li ethanol thiab ethers.
Siv:
Octanal diacetal muaj ntau yam kev siv hauv kev lag luam tshuaj. Octanal diacetal kuj tseem siv tau los ua cov khoom xyaw hauv tshuaj tua kab thiab tshuaj tua kab.
Txoj kev:
Kev npaj ntawm octanal diacetal tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm n-hexanal thiab ethanol. Feem ntau, n-hexanal thiab ethanol yog sib xyaw rau hauv ib qho molar piv, ua raws li cov tshuaj tiv thaiv ntawm qhov tsim nyog kub thiab siab, thiab thaum kawg ntshiab octanal diacetal yog sib cais los ntawm distillation.
Cov ntaub ntawv kev nyab xeeb: Octanal diacetal yog ib qho tshuaj lom neeg uas yuav ua rau khaus thiab mob ntawm daim tawv nqaij thiab qhov muag, thiab yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag ncaj qha. Cov cuab yeej tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv yuav tsum hnav thaum ua haujlwm. Thaum khaws cia thiab thauj, kev sib cuag nrog cov oxidants thiab cov kua qaub muaj zog yuav tsum zam kom tsis txhob muaj kev phom sij txaus ntshai. Thaum tsis siv, nws yuav tsum tau muab kaw kom zoo thiab khaws cia kom tsis txhob muaj kev sib cuag nrog hluav taws. Nyob rau hauv cov ntaub ntawv ntawm kev huam yuaj los yog inhalation, nrhiav kev kho mob tam sim ntawd.
