METHOD FOR OBTAINING ALKYL DERIVATIVES OF ARENES Russian patent published in 2021 - IPC C07C2/70 C07C15/107 C07C15/20

Abstract RU 2756954 C1

FIELD: chemical industry.

SUBSTANCE: invention relates to two variants of a method for obtaining alkyl derivatives of arenes: alkylation of arenes in the presence of methanesulfonic acid. According to one of the variants, the method is characterized by the fact that an undivided mixture of cracking products of raw materials containing high-molecular paraffins is used as an alkylating agent.

EFFECT: simplification (increase in efficiency) of the method for obtaining linear alkyl derivatives of arenes by eliminating the time-consuming stage of preliminary fractionation of the feedstock in order to obtain the target fraction of linear alpha-olefins C₉-C₁₄ (preferably the fraction of linear alpha-olefins C₁₀-C₁₄), used as an alkylating agent.
