C07C2/18 - CPC Classification

Classification description:

Preparation of hydrocarbons from hydrocarbons containing a smaller number of carbon atoms by addition between unsaturated hydrocarbons by oligomerisation of well-defined unsaturated hydrocarbons without ring formation of alkenes, i.e. acyclic hydrocarbons having only one carbon-to-carbon double bond; Catalytic processes with inorganic acids; with salts or anhydrides of acids Acids of phosphorus; Salts thereof; Phosphorus oxides
