FIELD: chemistry.

SUBSTANCE: invention relates to a method for synthesis of branched olefins, said method involving dehydrogenation of an isoparaffin composition containing 0.5% or less quaternary aliphatic carbon atoms on a suitable catalyst. Said isoparaffin composition is obtained via hydroisomerisation a paraffin composition and contains paraffin containing 7-18 carbon atoms. Said paraffins, at least some of their molecules, are branched, where content of branched paraffins in the isoparaffin composition is equal to at least 50% of the weight of the isoparaffin composition. The average number of branches per paraffin molecule is between 0.5 and 2.5 and the branches include methyl and optional ethyl branches. Said branched olefins contain 0.5% or less quaternary aliphatic carbon atoms. Said paraffin composition is obtained using Fischer-Tropsch method. The invention also relates to methods of producing a branched alkyl aromatic hydrocarbon and branched alkylaryl sulphonates including the method described above.

EFFECT: high versatility and cost effectiveness of the method.
