Abstract

The surfactants which can be produced from the trialkylamine intermediates include the quaternary ammonium compounds of formula:

First claim

We claim:

1. A quaternary ammonium compound of the formula:

wherein R8 is methyl, ethyl, butyl, or benzyl, and X is a halide or alkosulfate,
wherein R5 and R6 are independently selected from the group consisting of C 3 H 7 , C 2 H 5 , and CH 3 ; and
wherein R7 is selected from the group consisting of C 3 H 7 , C 2 H 5 , CH 3 and H.

2. The quaternary ammonium compound of claim 1 wherein R6 is C2H5.

3. The quaternary ammonium compound of claim 1 wherein R5 and R6 independently are C2H5.

4. The quaternary ammonium compound of claim 1 wherein R5 is CH 3 .

5. The quaternary ammonium compound of claim 4 wherein R5 is CH3 and R6 is C2H5.

6. The quaternary ammonium compound of claim 1 wherein R8 is benzyl or butyl.

7. The quaternary ammonium compound of claim 6 wherein X— is halide.

8. The quaternary ammonium compound of claim 6 selected from N-benzyl-2,4-diethyl-N,N-dimethyloctan-1-aminium chloride or N-butyl-2,4-diethyl-N,N-dimethyloctan-1-aminium bromide.

9. A composition comprising the quaternary ammonium compound of claim 1 .

10. A composition comprising the quaternary ammonium compound of claim 9 wherein the composition does not contain combinations with other quaternary ammonium compounds.

11. The quaternary ammonium compound of claim 1 which is a disinfecting agent.

12. The quaternary ammonium compound of claim 11 having a minimum lethal concentration against at least one microbe selected from gram-positive bacteria, gram-negative bacteria, or yeast, when used at concentrations of less than 200 ppm.

13. The quaternary ammonium compound of claim 12 having a minimum lethal concentration against E. coli, S. aureus and C - albicans when used at concentrations of less than 200 ppm.
