Abstract
Abstract A process for the use of ω-Aminocarboxylic acid amides of the formula ##STR1## wherein R is an aliphatic hydrocarbon residue having 10 to 14 carbon atoms, R 1 and R 2 are selected from the group consisting of hydrogen, methyl, --CH 2 --CH 2 OH, --CH 2 --CHOH--CH 3 and --CH 2 --CHOH--CH 2 OH, and m and n are integers from 1 to 10, to prevent the growth of microorganisms including compositions of phosphonate sequestering agents and ω-aminocarboxylic acid amides for use in industrial water treatment.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
105 words
A process for combatting microorganisms selected from the group consisting of gram-positive bacteria, gramnegative bacteria, fungi and algae which consists in contacting said microorganisms with a toxic amount of a ω-aminocarboxylic acid amide of the formula ##STR17## wherein R is an aliphatic hydrocarbon residue having from 10 to 14 carbon atoms selected from the group consisting of alkyl and alkenyl, R 1 and R 2 are members selected from the group consisting of hydrogen, methyl, --CH 2 --CH 2 OH, --CH 2 --CHOH--CH 3 and --CH 2 --CHOH--CH 2 OH, and n is an integer from 1 to 10, and their toxicologically-unobjectable acid addition salts.
Claim 2
Dependent Claim
105 words
A process for combatting microorganisms selected from the group consisting of gram-positive bacteria, gramnegative bacteria, fungi and algae which consists in contacting said microorganisms with a toxic amount of a ω-aminocarboxylic acid amide of the formula ##STR17## wherein R is an aliphatic hydrocarbon residue having from 10 to 14 carbon atoms selected from the group consisting of alkyl and alkenyl, R 1 and R 2 are members selected from the group consisting of hydrogen, methyl, --CH 2 --CH 2 OH, --CH 2 --CHOH--CH 3 and --CH 2 --CHOH--CH 2 OH, and n is an integer from 1 to 10, and their toxicologically-unobjectable acid addition salts.
Claim 3
Dependent Claim
10 words
The process of claim 1 wherein said microorganisms are algae.
Claim 4
Dependent Claim
35 words
The process of claim 1 wherein said microorganisms are in aqueous suspension and said ω-aminocarboxylic acid amide is employed in an amount of from 0.5 mgm to 50 mgm per liter of said aqueous suspension.
Claim 5
Dependent Claim
13 words
The process of claim 3 wherein said aqueous suspension is industrial process water.
