Description of key information

Naphthenate anions consist of hydrocarbons that are not subject to hydrolysis because they lack functional groups that hydrolyse.

Additional information

Hydrolysis of an organic chemical is the transformation process in which a water molecule or hydroxide ion reacts to form a new carbon--oxygen bond. Chemicals that have a potential to hydrolyze include alkyl halides, amides, carbamates, carboxylic acid esters and lactones, epoxides, phosphate esters, and sulfonic acid esters (Hams, 1982). source: Hams, J.C. 1982. Rate of hydrolysis. In; Handbook of Chemical Property Estimation Methods. W.L. Lyman, W.F. Reehl, and D.H. Rosenblastt, eds. Mcgraw-Hill Book Co., New Vork, NY. The chemical components of naphthenic acids are hydrocarbons that are not subject to hydrolysis because they lack functional groups that hydrolyse.
