FIELD: petrochemical processes.
SUBSTANCE: branched olefins are obtained via dehydrogenation of isoparaffin composition containing 0.5% or less quaternary aliphatic carbon atoms in presence of suitable catalyst. Isoparaffin composition is prepared via hydrocracking and hydroisomerization of paraffin wax and contains paraffins with 7 to 18 carbon atoms, these paraffins or at least a part of them are branched with average number of branches between 0.5 and 2.5 per paraffin molecule, the branches including methyl and optionally ethyl ones. Original paraffin wax is prepared using Fischer-Tropsch reaction. Resulting branched olefins are characterized by content of quaternary aliphatic structures 0.5% or less. Branched aromatic hydrocarbon and compositions of branched olefins, branched aromatic hydrocarbon, and branched alkylarenesulfonates are also disclosed.
EFFECT: improved quality characteristics of target products.
