FIELD: chemistry.

SUBSTANCE: proposed method of producing branched olefins involves dehydrogenation of an isoparaffin composition, containing 0.5% or less quaternary aliphatic carbon atoms, on a suitable catalyst. The above mentioned isoparaffin composition contains paraffins with 7 to 35 carbon atoms. These paraffins, or at least part of their molecules, are branched. The average number of branches per paraffin molecule ranges from 0.7 to 2.5, and the branches include methyl and, optionally, ethyl branches. The above mentioned isoparaffin composition is obtained through hydroisomerisation of paraffin, and the above mentioned branched olefins contain 0.5% quaternary carbon atoms or less. The paraffins are produced using Fischer-Tropsch method. The invention also relates to the method of producing a surface active substance from olefins, obtained using the method described above.

EFFECT: improvement of operational characteristics.
