Kuj nug, koj yuav txheeb xyuas li cas acyl chloride?
Ib acyl chloride tshuaj zoo li ethanoyl tshuaj chloride yog cov kua uas tsis muaj xim fuming. Cov ntxhiab tsw muaj zog ntawm ethanoyl tshuaj chloride yog ib tug sib tov ntawm tsis hnov tsw ntawm vinegar (ethanoic kua qaub ) thiab tsis hnov tsw ntawm hydrogen tshuaj chloride roj. Cov ntxhiab tsw thiab cov pa taws yog vim ethanoyl tshuaj chloride reacts nrog dej vapor hauv huab cua.
Tsis tas li ntawd, acyl chlorides siv rau dab tsi? Acyl chlorides yog siv npaj kua qaub anhydrides, esters, thiab amides los ntawm reacting kua qaub chlorides nrog: ntsev ntawm carboxylic kua qaub , cawv, los yog amine, feem.
Ntawm no, ua li cas acyl chlorides tsim?
Cov sulfur dichloride oxide reacts nrog carboxylic acids los tsim ib qho acyl chloride tshuaj , thiab sulfur dioxide thiab hydrogen tshuaj chloride gases muab tawm. Piv txwv li: Cov kev sib cais yog yooj yim mus rau ib tug npaum li cas vim hais tias cov by-products yog ob qho tib si gases.
Yog vim li cas acyl chloride ntau reactive?
Acyl chlorides yog cov feem ntau reactive carboxylic kua qaub derivatives. Lub electronegative tshuaj atom rub electrons mus rau nws hauv C-Cl daim ntawv cog lus, uas ua rau carbonyl carbon ntau electrophilic. Qhov no ua rau nucleophilic nres yooj yim dua. Tsis tas li ntawd, Cl- yog ib pab pawg tawm zoo heev, yog li ntawd cov kauj ruam tseem ceev.
