DEFINITION

Classification: 568/950

Processes of oxidizing nonaromatic hydrocarbons; or purification or recovery of the products of such processes:

(under subclass 300) Processes which are directed to the oxidation on nonaromatic hydrocarbons or processes which include separating the products of the oxidation from impurities or from the reaction mixture.

(1) Note. Included herein are processes of oxidizing hydrocarbon mixtures, e.g., petroleum, fractional distillates of petroleum, paraffin, pine oil, turpentine, etc., to produce a mixture of oxygen-containing products, such as a mixture of esters, acids, aldehydes, ketones, and alcohols.

(2) Note. This subclass provides for producing oxygenated hydrocarbon mixtures broadly or mixtures of oxygen-containing compounds, such as a mixture of aldehydes, ketones, and alcohols, by oxidizing nonaromatic hydrocarbons. Oxidation of hydrocarbons to produce a specific compound is classified with the compound. In the situation where a "limited class of compounds" is produced, the patent is classified with that class of compounds and is assumed to be an acyclic compound. Some examples of such "limited class of compounds" are aldehydes, ketones, alcohols, and carboxylic acids. If "acids" are made by oxidizing nonaromatic hydrocarbon mixtures it is assumed an acyclic carboxylic acid results. Thus, if a process sets forth production of acids by oxidizing nonaromatic hydrocarbons, it is classified as an acyclic carboxylic acid.
