O-Chem in Real Life: Soaps and Detergents - ASU

O-Chem in Real Life: Soaps and Detergents. The definition of a carboxylic acid derivative is a compound that hydrolyzes (usually with an acid or base catalyst) to a carboxylic acid. An ester hydrolyzes to a carboxylic acid and an alcohol. If this hydrolysis is performed in the presence of base, then the anionic form of the carboxylic acid is ...

Soap cleans because each soap molecule consists of a hydrocarbon chain and a carboxylic group (fatty acids) that perform two important functions. The carboxylate end of the soap molecule is hydrophilic, meaning that it is attracted to water, while the hydrocarbon end of the molecule is both hydrophobic (repelled by water) and attracted to the ...

3.4.5 Compounds Containing the Carbonyl Group - Carboxylic ...

Carboxylic acids are able to release hydrogen ions in solution, as the carboxylate ion is stabilised by resonance delocalisation. However, the equilibrium does not go very far and a typical organic acid dissociates about 1% in aqueous solution. CH 3 COOH CH 3 COO-+ H + This does not mean that carboxylic acids are unable to react as acids.

tr Natural Products Chemistry & Research

the fatty acids react with the alkali to form metal salts called soaps. It is known that there are more than 100 oils that are used in soap production which occur in most varieties [1]. But unfortunately, most of the soaps form non-saponifiable fatty acids and cannot be suitable for soap production.

4« "Soap" is the salt made by combining a metallic ion with a water= insoluble normal carboxylic (fatty) acid« In common usage, soap is a commercial cleansing and sudsing agent made of water-soluble salts of fatty and other natural acids« Thus, by definition, soap is differientiated from other deter- gents (_3)o

Utility of branched chain carboxylic acids in the ...

To be useful in the manufacture of driers, a carboxylic acid must yield lead, cobalt, manganese, calcium and zinc soaps which are soluble in paint vehicles and petroleum hydrocarbon thinners. The drying metal soaps of a number of saturated branched chain carboxylic acids were prepared to determine the relationship of acid structure to metal soap solubility. It was found that with the …
