Taw qhia
6-Chloronicotinaldehyde (tseem hu ua 2,4,6-chlorobenzoic acid aldehyde) yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 6-chloronicotinaldehyde:
Khoom: 6-Chloronicotinaldehyde yog cov xim tsis muaj xim lossis dawb crystalline hmoov nrog cov ntxhiab tsw. Nws muaj qhov sib txawv nruab nrab thiab tuaj yeem yaj hauv ntau cov kuab tshuaj organic xws li cawv, ethers, thiab ketones. Nws yuav luag insoluble hauv dej tab sis tuaj yeem yaj hauv cov kuab tshuaj organic.
Siv: 6-Chloronicotinaldehyde feem ntau yog siv los ua ib qho reagent thiab nruab nrab hauv cov organic synthesis. Nws yog siv los ua raw khoom rau tshuaj tua kab, tshuaj tua kab, thiab fungicides hauv kev ua liaj ua teb.
Txoj kev npaj: 6-chloronicotinaldehyde tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm benzoyl chloride thiab txhuas chloride. Cov tshuaj tiv thaiv tuaj yeem ua tau ntawm chav tsev kub. Txoj kev tshwj xeeb synthesis yog raws li nram no:
C6H5COCl + AlCl3 -> C6H4ClCOCl + HCl
C6H4ClCOCl + HCl -> C7H3Cl3O + CO2 + HCl
Cov ntaub ntawv kev nyab xeeb: 6-Chloronicotinaldehyde ua rau khaus, tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag. Kev tiv thaiv tus kheej tsim nyog yuav tsum tau ua thaum siv, xws li hnav hnab looj tes, looj tsom iav, thiab lub ntsej muag tiv thaiv. Tsis txhob nqus nws cov vapors lossis hmoov av thaum ua haujlwm. Thaum khaws cia thiab tuav 6-chloronicotinal, ua raws li cov txheej txheem kev nyab xeeb uas cuam tshuam thiab khaws cia rau hauv lub thawv kom zoo. Thaum pov tseg cov khoom pov tseg, nws yuav tsum muab pov tseg kom tsim nyog raws li cov cai hauv zos.
