A process for production of higher linear alpha olefins and/or alkyl-branched alpha olefins, which comprises the co-oligomerisation of one or more alpha olefins with ethylene in the presence of a metal catalyst system employing one or more bis-aryliminepyridine MXcomplexes and/or one or more [bis-aryliminepyridine MY.L][NC]complexes; and said process is carried out at an ethylene pressure of less than 2.5 MPa.

Process for the co-oligomerisation of ethylene and alpha olefins

The invention relates to a detergent composition comprising an internal olefin sulfonate salt having from 8 to 26 carbon atoms, wherein at least 25% by weight of the internal olfein sulfonate salt is in the beta-hydroxy alkane sulfonate form. It has been found that internal olefin sulfonate salts having enhanced beta-hydroxy alkane sulfonate content provide excellent detergency.
