ALKENYL OR ALKYLSINNAMIC ACID ANHYDRIDE CONTAINING SULFONIC ACID, AMIDE AND CARBOXYL GROUPS IN ONE MOLECULE AND SALT THEREOF, CLEANER COMPOSITION CONTAINING THE SAME

摘要

NEW MATERIAL:Alkenyl or alkylsinnamic acid anhydride derivatives containing sulfone, amide and carboxyl groups in the molecule and represented by formula I and II (R is alkenyl or alkyl; R' is H or hydrocarbon) and salts thereof. EXAMPLE:The reaction product of n-tetradecenylsinnamic acid anhydride with N-methyltaurine sodium salt. USE:Cleansing agents which are low irritative and have excellent surface-active performance. PREPARATION:For example, a compound of formula III is made to react with a compound of formula IV to prepare the compounds of formulas I and II, which are, if desired, converted into salts of formula V and/or VI.
