saponification
sa·pon·i·fi·ca·tion S0083700 (sə-pŏn′ə-fĭ-kā′shən)n. A reaction in which an ester is heated with an alkali, such as sodium hydroxide, producing a free alcohol and a carboxylate salt, especially alkaline hydrolysis of a fat or oil to make soap.ThesaurusNoun | 1. | saponification - a chemical reaction in which an ester is heated with an alkali (especially the alkaline hydrolysis of a fat or oil to make soap)chemical reaction, reaction - (chemistry) a process in which one or more substances are changed into others; "there was a chemical reaction of the lime with the ground water" | TranslationsSaponification
saponification[sə‚pän·ə·fə′kā·shən] (chemistry) The process of converting chemicals into soap; involves the alkaline hydrolysis of a fat or oil, or the neutralization of a fatty acid. Saponification the hydrolysis of carboxylic and derivatives, including esters, nitriles, and amides, for example RCOOR’ + H2O → RCOOH + R’OH Saponification is widely used in industry to produce acids and alcohols. Higher aliphatic carboxylic acids, glycerol, soaps, and stearic acid are formed upon saponification of fats. saponificationThe conversion into soap which occurs when an alkali, such as the lime in cement, reacts with oils in paint; destroys the adhesion and strength of oil-based paint films.saponification
saponification [sah-pon″ĭ-fĭ-ka´shun] conversion of an oil or fat into a soap by combination with an alkali. In chemistry, the term now denotes the hydrolysis of an ester by an alkali, resulting in the production of a free alcohol and an alkali salt of the ester acid.sa·pon·i·fi·ca·tion (să-pon'i-fi-kā'shŭn), Conversion into soap, denoting the hydrolytic action of an alkali on fat, especially on triacylglycerols; in histochemistry, saponification is used to demethylate or reverse blockage of carboxylic acid groups, thus permitting basophilia to occur.
