Title:
PRODUCTION OF AMINE OXIDE-TYPE SURFACTANT
Document Type and Number:
Japanese Patent JP3505366
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To produce the subject surfactant having a high quality and prevent gel-formation during the production process through a smooth reaction by reacting a specific amine of a specific concentration with hydrogen peroxide in an aqueous solvent.
SOLUTION: (A) An amine of formula I [R1 is a (ester bond-, amide bond- or ether bond-containing) 8-22C normal or branched alkyl or alkenyl; R2 is a 2-6C normal or branched alkylene; R3 and R4 are each a 1-4C alkyl or hydroxyalkyl; A is O, C(=O)NH or NHC(=O); (n)=0-10] is made to react with (B) hydrogen peroxide in (C) an aqueous solvent (e.g. water) while keeping the concentration of the component A in the reaction system at 5 wt.% or below, preferably 4 wt.% or below, to obtain the objective surfactant of formula II. A preferable method to be applied to the production is an amine addition method in which the component A is added to the component B or a simultaneous addition method in which the component A and the component B are added simultaneously.
