Mixture of surfactants from alpha-olefine sulfonates and other surfactants

Abstract

Abstract 1. Claims (for the Contracting States : BE, CH, DE, FR, GB, IT, LI, NL, SE) Surfactant mixtures which are composed of 20 to 80% by weight of a C12 -C20 alpha-olefinsulfonate and 20 to 80% by weight of one or more compounds of the formulae RCONH-(CH2 CH2 O)n -SO3 X in which R denotes C7 -C17 alkyl, n denotes a number from 0 to 4 and X denotes an alkali metal ion, alkaline earth metal ion or alkanolammonium ion, see diagramm : EP0068352,P6,F6 in which R and X have the same meaning as in formula (1), see diagramm : EP0068352,P6,F7 in which R1 denotes C12 -C14 alkyl, n denotes a number from 0 to 5 and Y denotes an alkali metal ion, see diagramm : EP0068352,P6,F8 in which R2 denotes C10 -C14 alkyl, n denotes 2 or 3 and R3 denotes C1 -C4 alkyl, see diagramm : EP0068352,P7,F1 in which R4 denotes C10 -C18 alkyl and R3 denotes C1 -C4 alkyl, and see diagramm : EP0068352,P7,F2 in which R4 denotes C10 -C18 alkyl, n denotes 2 or 3 and R3 denotes C1 -C4 alkyl. 1. Claims (for the Contracting State AT) Process for the preparation of surfactant mixtures by mixing an alpha-olefinsulfonate with at least one further surfactant which process in characterized in that 20 to 80% by weight of a C12 -C20 alpha-olefinsulfonate are mixed with 20 to 80% by weight of one or more compounds of the formulae RCONH-(CH2 CH2 O)n -SO3 X in which R denotes C7 -C17 alkyl, n denotes a number from 0 to 4 and X denotes an alkali metal ion, alkaline earth metal ion or alkanolammonium ion, see diagramm : EP0068352,P7,F3 in which R and X have the same meaning as in formula (1), see diagramm : EP0068352,P7,F4 in which R1 denotes C12 -C14 alkyl, n denotes a number from 0 to 5 and Y denotes an alkali metal ion, see diagramm : EP0068352,P7,F5 in which R2 denotes C10 -C14 alkyl, n denotes 2 or 3 and R3 denotes C1 -C4 alkyl, see diagramm : EP0068352,P7,F6 in which R4 denotes C10 -C18 alkyl and R3 denotes C1 -C4 alkyl, and see diagramm : EP0068352,P7,F7 in which R4 denotes C10 -C18 alkyl, n denotes 2 or 3 and R3 denotes C1 -C4 alkyl.
