FIELD: chemistry.
SUBSTANCE: method for producing alkyl salicylic acid involves alkylation by the reaction of a long chainα-olefin and salicylic acid in a molar ratio of 1:1.05 to 1:1.14 in the presence of a heterogeneous sulphocathionite catalyst having a BET specific surface area of not more than 24 m2/g and not less than 22 m2/g.
EFFECT: simplification of the method and increased output of the target product.
