DEFINITION

Classification: 508/460

Overbased or carbonated carboxylates:

(under subclass 459) Compositions wherein the organic -C(=O)O- compound is an overbased or carbonated carboxylic acid.

(1) Note. An overbased compound herein is one in which an amount of metal (e.g., Mg, Ca, Ba, Sr) is present which is greater than the stoichiometric amount of metal which would be present if the carboxylic acid were completely neutralized.

(2) Note. A carbonated compound herein is the complex resulting from the reaction of carbon dioxide with metal carboxylates.
