Abstract
A PROCESS FOR PREPARING BRANCHED OLEFINS WHICH PROCESS COMPRISES DEHYDROGENATING AN ISOPARAFFINIC COMPOSITION COMPRISING 0.5% OR LESS QUATERNARY ALIPHATIC CARBON ATOMS OVER A SUITABLE CATALYST, WHICH ISOPARAFFINIC COMPOSITION COMPRISES PARAFFINS HAVING A CARBON NUMBER IN THE RANGE OF FROM 7 TO 35, OF WHICH PARAFFINS AT LEAST A PORTION OF THE MOLECULES IS BRANCHED, THE AVERAGE NUMBER OF BRANCHES PER PARAFFIN MOLECULE BEING FROM 0.7 TO 2.5 AND THE BRANCHING COMPRISING METHYL AND OPTIONALLY ETHYL BRANCHES, AND WHICH ISOPARAFFINIC COMPOSITION MAY BE OBTAINED BY HYDROCRACKING AND HYDROISOMERISATION OF A PARAFFINIC WAX, SAID BRANCHED OLEFINS HAVING A QUATERNARY CARBON CONTENT OF 0.5OR LESS; A PROCESS OF USING OLEFINS FOR MAKING AN ANIONIC SURFACTANT, A NONIONIC SURFACTANT OR A CATIONIC SURFACTANT, IN PARTICULAR A SURFACTANT SULPHATE OR SULPHONATE, COMPRISING CONVERTING THE BRANCHED OLEFINS INTO THE SURFACTANT, AND AN ANIONIC SURFACTANT, A NIONIC SURFACTANT OR A CATIONIC SURFACTANT WHICH IS OBTAINABLE BY SAID PROCESS.
