Abstract
ABSTRACTIn the article we discuss the results of a comparison of interfacial activity and component composition data for petroleum sulfonates (PS) synthesized from an extract of selective N-MP refining of side stream II and for dimeric PS prepared from the same source in the presence of paraform (paraformaldehyde)—a component responsible for the formation of disulfonic acids. The prepared technical anionic PS are characterized by a higher molecular mass (688 g/mol) and lower CMC values (40-fold for the mass 120 concentration and 500-fold for the molar concentration) relative to paraform-free sulfonation of hydrocarbons. Surfactants with low CMC values sourced from the low-quality multitonnage hydrocarbon feedstock are promising in a search of formulations for chemical flooding of reservoirs.
