摘要: The invention relates to a method for producing acyloxy benzoic acids of the formula (I), in which R1 is a linear or branched saturated alkyl group with 6 to 30 carbon atoms, a linear or branched mono- or polyunsaturated alkenyl group with 6 to 30 carbon atoms, or an aryl group with 6 to 30 carbon atoms. The acyloxy benzoic acids of the formula (I) are produced from para-hydroxy benzoic acid and a corresponding carboxylic acid halogenide in the presence of a base and are advantageously suitable for use as activators for hydrogen peroxide.

摘要: This invention relates to a method for producing compounds of formula (I) wherein R1 is a straight- or branched-chain C1-C24 alkyl, C2-C24-alkenyl or C1-C24-alkyl ether group or CH2CN or a group of the formula R2 and R3 are each individually a C1-C8-alkyl or C1-C4-hydroxyalkyl group. The method according to the invention is characterized by reacting a tertiary amine of the formula NR1R2R3 with chloroacetonitrile in an organic solvent and then adding an alkylating substance R11-Z, being C1-C4 alky.
