N-(2-hydroxy-higher hydrocarbyl)-n-lower hydrocarbyl-aminocarboxylates

Abstract

Abstract N-(2-HYDROXY-HIGHER HYDROCARBYL)-N-LOWER HYDROCARBYL-AMINOCARBOXYLATES OR THE CORRESPONDING AMINOCARBOXYLIC ACIDS ARE OF THE FORMULA R1-CH(-OH)-CH2-N(-R2)-R3-COO-X WHEREIN R1 IS AN ALIPHATIC HYDROCARBON RADICAL OF 10 TO 20 CARBON ATOMS, R2 IS A HYDROCARBON RADICAL OF 1 TO 4 CARBON ATOMS, R3 IS A DIVALENT ALIPHATIC OR AROMATIC HYDROCARBON RADICAL OF 1 TO 9 CARBON ATOMS, AND X IS EITHER HYDROGEN OR A SALT-FORMING ELEMENT OR RADICAL. IN PREFERRED ENBODIMENTS OF THE INVENTION, R1 IS AN ACYCLIC SATURATED RADICAL OF 12 TO 16 CARBON ATOMS, R2 IS METHYL, R3 IS OF 1 TO 2 CARBON ATOMS, AND X IS A MONOVALENT METAL OR AN ALKANOLAMINE, SUCH AS SODIUM OR TRIETHANOLAMINE. THE NOVEL COMOUNDS ARE SURFACE ACTIVE AND MANY EXHIBIT EXCELLENT SUBSTANTIVITIES TO FIBROUS MATERIALS, ESPECIALLY COTTON. THEY ARE USEFUL AS DETERGENTS OR AS CONSTITUENTS OF DETERGENT PREPARATIONS. PREFERRED COMPOUNDS FUNCTION VERY EFFECTIVELY AS SOFTENING AGENTS, WHICH MAY BE EMPLOYED IN THE FINAL RINSING OF LAUNDRY OR TEXTILES, IF USED ALONE OR IN CONJUNCTION WITH OTHER DETERGENT COMPOSITION MATERIALS, IN THE WASH WATER. THE PRESENT N-(2HYDROXY-HIGHER HYDROCARBYL)-N-LOWER HYDROCARBYL-AMINOCARBOXYLATES MAY ALSO BE CONVERTED TO THE CORRESPONDING N-OXIDES, WHICH ARE ALSO EFFECTIVE DETERGENTS, AND MANY OF WHICH MAY BE EMPLOYED AS EXCELLENT SOFTENING AGENTS FOR LAUNDRY AND TEXTILES.
