FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining acylated alkoxylate of secondary alcohol of formula R¹-C(O)-(OA)_n-OR²(I), in which R¹ is linear or branched alkyl group, including from 1 to 30 carbon atoms, optionally substituted cycloalkyl group, which includes from 5 to 30 carbon atoms, or optionally substituted aryl group, including from 6 to 30 carbon atoms, OA stands for one or several oxyalkylene fragments, which can be similar or different, n stands for integer number in the range from 0 to 70, and R² is linear or branched alkyl group, including from 4 to 32 carbon atoms, optionally substituted cycloalkyl group, including from 5 to 32 carbon atoms, or optionally substituted bicycloalkyl group, including from 7 to 32 carbon atoms, where claimed method includes: (i) interaction of one or several olefins with internal double bond with one or several carboxylic acids in presence of catalytic composition with obtaining one or several ethers of carboxylic acid; (ii) interaction of one or several ethers of carboxylic acid, obtained at stage (i), with one or several alkylene oxide reagents in presence of catalytically efficient quantity of catalytic composition, which includes: (a) one or several salts of alkali earth metals and carboxylic acids and/or hydroxycarboxylic acids, which include 1-18 carbon atoms, and/or hydrates of the former; (b) oxygen-containing acid, selected from sulfuric acid and orthophosphoric acid; (c) alcohol, containing from 2 to 39 carbon atoms; and/or products of (a), (b) and/or (c) interactions with obtaining one or several acylated alkoxylates of secondary alcohols.

EFFECT: invention also relates to methods of obtaining alkoxylates of secondary alcohols and alkoxy sulfates of secondary alcohols, including the claimed method.
