Abstract
Abstract An amino-ether amphoteric surface-active compound mixture produced by reacting a glycidyl ether having the formula <IMAGE> wherein R'' is a member selected from the group consisting of hydrogen and methyl; R' is a member selected from the group consisting of aliphatic primary alkyl having from 8 to 22 carbon atoms, aliphatic primary alkenyl having from 12 to 20 carbon atoms and 2-alkylalkanols having from 10 to 36 carbon atoms; and p is an integer from 0 to 3; with a substantial excess of an N-hydroxy-C2-4-alkyl-C2-6-alkylene diamine, removing the excess diamine, reacting the resulting substituted amino-ether with an excess of an N-alkylating agent selected from the group consisting of halo-C2-4-alkanoic acids, halo-C2-4-alkane sulfonic acids and halo-C3-4-hydroxyalkane sulfonic acids, under alkaline reaction conditions and recovering said amino-ether amphoteric surface-active compound mixture.

Claim 1
Independent Claim
159 words
An amino-ether amphoteric surface-active compound mixture produced by reacting a glycidyl ether having the formula ##STR20## wherein R" is a member selected from the group consisting of hydrogen and methyl; R' is a member selected from the group consisting of aliphatic primary alkyl having from 8 to 22 carbon atoms, aliphatic primary alkenyl having from 12 to 20 carbon atoms and 2-alkylalkanols having from 10 to 36 carbon atoms; and p is an integer from 0 to 3; with a substantial excess of an N-hydroxy-C 2-4 -alkyl-C 2-6 -alkylene diamine, removing the excess diamine, reacting the resulting substituted amino-ether with from 1.5 mols to 4 mols per mol of said substituted amino-ether of an N-alkylating agent selected from the group consisting of halo-C 2-4 -alkanoic acids, halo-C 2-4 -alkane sulfonic acids and halo-C 3-4 -hydroxyalkane sulfonic acids, under alkaline reaction conditions maintained by the addition of an alkali metal hydroxide solution, and recovering said amino-ether amphoteric surface-actice compound mixture.
Claim 2
Dependent Claim
159 words
An amino-ether amphoteric surface-active compound mixture produced by reacting a glycidyl ether having the formula ##STR20## wherein R" is a member selected from the group consisting of hydrogen and methyl; R' is a member selected from the group consisting of aliphatic primary alkyl having from 8 to 22 carbon atoms, aliphatic primary alkenyl having from 12 to 20 carbon atoms and 2-alkylalkanols having from 10 to 36 carbon atoms; and p is an integer from 0 to 3; with a substantial excess of an N-hydroxy-C 2-4 -alkyl-C 2-6 -alkylene diamine, removing the excess diamine, reacting the resulting substituted amino-ether with from 1.5 mols to 4 mols per mol of said substituted amino-ether of an N-alkylating agent selected from the group consisting of halo-C 2-4 -alkanoic acids, halo-C 2-4 -alkane sulfonic acids and halo-C 3-4 -hydroxyalkane sulfonic acids, under alkaline reaction conditions maintained by the addition of an alkali metal hydroxide solution, and recovering said amino-ether amphoteric surface-actice compound mixture.
Claim 3
Dependent Claim
20 words
An aqueous solution containing from 0.05% to 50% by weight of the amino-ether amphoteric surface-active compound mixture of claim 1.
