Saponification tsuas yog txheej txheem ntawm kev ua xab npum. … Thaum lub sij hawm saponification, ester reacts nrog lub hauv paus inorganic los tsim cawv thiab xab npumFeem ntau, nws tshwm sim thaum triglycerides reacted nrog poov tshuaj los yog sodium hydroxide (lye) los tsim glycerol thiab fatty acid ntsev, hu ua 'xab'.
Yuav ua li cas hauv cov tshuaj tiv thaiv saponification?
Saponification yog ib qho tshuaj tiv thaiv exothermic-uas txhais tau hais tias nws muab cov cua sov-uas tshwm sim thaum fas lossis roj (fatty acids) tuaj rau hauv kev sib cuag nrog lye, lub hauv paus Hauv qhov no Cov tshuaj tiv thaiv, cov triglyceride units ntawm cov rog hnov mob nrog sodium hydroxide lossis potassium hydroxide thiab hloov mus rau xab npum thiab glycerol.
Saponification cov tshuaj tiv thaiv yog dab tsi?
Thaum ester kho nrog alkali, cov tshuaj tiv thaiv muab ethanol thiab sodium ethanoate. Cov tshuaj tiv thaiv no yog hu ua saponification cov tshuaj tiv thaiv vim tias cov tshuaj tiv thaiv no tsim lub hauv paus ntawm kev npaj xab npum. Qhov no tuaj yeem muab los ntawm kev sib npaug hauv qab no. CH3COOC2H5+NaOH→CH3COONa+C2H5OH.
Cov tshuaj tiv thaiv ntawm tus nqi saponification yog dab tsi?
Saponification tuaj yeem ua tus yam ntxwv raws li "cov tshuaj tiv thaiv dej uas tsis muaj hydroxide rhuav tshem khi ntawm ester ntawm triglyceride fatty acids thiab glycerol, ua rau cov roj ntsha dawb thiab glycerol, "txhua tus uas yog soluble nyob rau hauv aqueous tov.
Saponification luv luv teb yog dab tsi?
Saponification yog hydrolysis ntawm ester nyob rau hauv acidic los yog yooj yim tej yam kev mob los tsim ib tug cawv thiab ntsev ntawm ib tug carboxylic acid. Saponification feem ntau yog siv los xa mus rau cov tshuaj tiv thaiv ntawm cov hlau alkali (lub hauv paus) nrog cov roj los yog roj los ua soap.
