Cov sulfur dichloride oxide reacts nrog carboxylic acids los tsim cov acyl chloride, thiab sulfur dioxide thiab hydrogen chloride gases raug muab tawm. Piv txwv li: Kev sib cais yog yooj yim mus rau ib tug npaum li cas vim hais tias cov by-products yog ob gases.
Acyl halides tsim li cas?
Ib acyl halide (tseem hu ua acid halide) yog cov tshuaj lom neeg muab tau los ntawm los ntawm oxoacid los ntawm kev hloov ib pawg hydroxyl nrog pawg halide. Yog hais tias cov kua qaub yog carboxylic acid, cov compound muaj ib pab pawg neeg ua haujlwm -COX, uas muaj cov pab pawg carbonyl singly bonded rau halogen atom.
Yuav ua li cas ua kua qaub halide?
Acid halides yog npaj los ntawm cov tshuaj tiv thaiv ntawm carboxylic acid nrog thionyl chloride (SOCl 2) lossis phosphorus tribromide (PBr 3). Hauv cov tshuaj tiv thaiv nrog thionyl chloride, cov pa oxygen los ntawm carbonyl tawm tsam cov sulfur atom, thiab ib qho ntawm cov chlorine atoms tawm ntawm thionyl chloride.
Acid thiab anhydride yog dab tsi?
Ib acid anhydride yog hom tshuaj lom neeg muab los ntawm kev tshem tawm cov dej molecules los ntawm cov kua qaub. … Hauv inorganic chemistry, cov kua qaub anhydride yog hais txog cov kua qaub oxide, ib qho oxide uas ua rau dej los tsim cov oxyacid (ib qho inorganic acid uas muaj cov pa oxygen lossis carbonic acid), los yog nrog lub hauv paus los ua ntsev.
ester formula yog dab tsi?
Carboxylic acid esters, formula RCOOR′ (R thiab R′ yog cov organiccombining pab pawg), feem ntau yog npaj los ntawm cov tshuaj tiv thaiv ntawm carboxylic acids thiab cawv nyob rau hauv lub xub ntiag ntawm hydrochloric acid los yog sulfuric acid, ib tug txheej txheem hu ua esterification.
