How does the structure of the detergent sodium lauryl sulfate differs from the soaps commonly synthesized in lab using coconut oil, NaOH, and ethanol?
Homework Answers
Sodium lauryl sulphate is anionic surfactants, it is sodium salt of organosulphate. It is ester of dodecyl hydrogen sulphate.
Commonly synthesized soaps are the sodium salt of long chain carboxylic acid. These are form by the hydrolysis of triglycerides i.e. saponification. This process breaks triglyceride at ester linkage and yields acid molecules and glycerol molecule.
In sodium lauryl sulphate COOH group replaced by -OH and then it replaced by -SO3-
Commonly used soap have carboxylate head group and sodium lauryl sulphate have sulphate head group.
