Sulfonic acid , sulfo thiab alky (nrog rau aryl) txuas nrog ib chav kawm ntawm cov organic compounds. Hom mis R-SO3H, R sawv cev ntawm cov roj carbon atom, cov acidity uas muaj zog, cov dej loj-soluble, uas siv los ua cov tshuaj dyes, tshuaj, cov tshuaj ntxhua khaub ncaws, muaj ntau hom kev tsim tawm.
R-SO3H ntawm cov qauv mis uas R yog ib pawg hydrocarbon. Sulfonic acid feem ntau khoom siv hluavtaws, tsuas yog β-amino ethanesulfonic acid NH2CH2CH2SO3H thiab ob peb lwm sulfonic acids nyob rau hauv qhov. Sulfonic acid yog ib qho dej-soluble muaj zog pawg, sulfonic acid yog dej-soluble muaj zog acid compounds. Aromatic sulfonic acid molecules nyob rau hauv lub sulfonic acid pawg yuav ua tau hydroxy, cyano-substituted, yog kev npaj ntawm phenol, nitrile intermediates. Sulfonic acids yuav npaj los ntawm sulfonation ntawm aromatic hydrocarbons, los yog oxidation ntawm thiols. Methanesulfonic acid tuaj yeem siv ua tus catalyst rau esterification, hydrolysis thiab alkylation. Cov yeeb koob ntev sulfonic acid sodium ntsev xws li n-C11H23-CH2 yog hoob kawm tawv dej uas tsis muaj zog resistant detergents. Sulfonic acid pawg nyob hauv ntau lub qos yaj ywm muaj peev xwm kav tau cov xim sib tov dej-soluble. Sodium dodecyl benzene sulfonate yuav siv tau ua xab npum. Chlorosulfone tuaj yeem tau los ntawm sulfonic acid, zoo siv cov organic synthesis 桹 H moiety hauv lub sulfonic acid molecule yuav muab nrog ib halogen atom, ib pawg amino, lossis zoo li. Piv txwv, sulfuryl chloride yog ib qho feem ntau siv cov khoom nruab nrab hauv cov organic synthesis thiab kev tshawb xyuas chemistry. Aminosulfonamides yog ib chav kawm ntawm cov tshuaj tiv thaiv. Sodium saccharin kuj yog sulfonamide
