FIELD: oil and gas industry.
SUBSTANCE: invention relates to a process of synthesis of technical petroleum sulfonates by sulfonating a hydrocarbon feed (extracts of solvent-refined oil fractions, aromatic concentrates, oil fractions, crude oils, oils) followed by neutralisation of the product obtained. The sulfonation process takes place in the presence of paraform.
EFFECT: oil dimer sulfonates are obtained with a high tendency to micelle formation for the needs of the oil industry.
