Abstract
Abstract The present invention relates to certain processes and compositions useful for inhibiting the growth of slime in water and, in particular, water used for industrial purposes; for example, in the manufacture of pulp paper, in the manufacture of paper, in cooling water systems and in effluent water treatment. The novel processes and compositions of the present invention are processes or mixtures which show unexpected synergistic activity against microorganisms, including bacteria, fungi, and algae, which produce slime in aqueous systems or bodies which are objectionable from either an operational or aesthetic point of view. Specifically, the invention is directed to the use of compositions comprising a combination 1,3-dichloroacetone oxime acetate and N-(2 nitrobutyl)-morpholine.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
41 words
A COMPOSITION FOR THE CONTROL OF THE MICROORGANISM AEROBACTER ACOGENES IN AQUEOUS SYSTEM COMPRISING A MIXTURE F1, 3-DICHLORACETONE OXIME ACETAE AND N-(2 NITROBUTYL)MORPHOLINE WHEREIN THE WEIGHT RATIO OF THE ACETATE TO THE MORPHALINE RANGES FROM ABOUT 95.5 TO ABOUT 5.95 RESPECTIVELY
Claim 2
Dependent Claim
41 words
A COMPOSITION FOR THE CONTROL OF THE MICROORGANISM AEROBACTER ACOGENES IN AQUEOUS SYSTEM COMPRISING A MIXTURE F1, 3-DICHLORACETONE OXIME ACETAE AND N-(2 NITROBUTYL)MORPHOLINE WHEREIN THE WEIGHT RATIO OF THE ACETATE TO THE MORPHALINE RANGES FROM ABOUT 95.5 TO ABOUT 5.95 RESPECTIVELY
Claim 3
Dependent Claim
11 words
The composition of claim 1 where said ratio is about 50:50.
Claim 4
Independent Claim
57 words
A method for controlling the growth of the microorganism Aerobacter aerogenes in an aqueous system which comprises adding to said system a growth inhibiting amount of a composition comprised of a mixture of 1,3-dichloroacetone oxime acetate and N-(2 nitrobutyl)-morpholine wherein the weight ratio of the acetate to the morpholine ranges from about 95:5 to about 5:95 respectively.
Claim 5
Independent Claim
57 words
A method for controlling the growth of the microorganism Aerobacter aerogenes in an aqueous system which comprises adding to said system a growth inhibiting amount of a composition comprised of a mixture of 1,3-dichloroacetone oxime acetate and N-(2 nitrobutyl)-morpholine wherein the weight ratio of the acetate to the morpholine ranges from about 95:5 to about 5:95 respectively.
Claim 6
Dependent Claim
11 words
The method of claim 3 where said ratio is about 50:50.
Claim 7
Dependent Claim
37 words
The method of claim 3 wherein said composition is added to said system in an amount of from 0.1 to about 1000 parts per weight of said composition per million parts by weight of said aqueous system.
Claim 8
Dependent Claim
23 words
The method of claim 5 where said composition amount is from about 1 to about 100 parts per million of said aqueous system.
Claim 9
Dependent Claim
16 words
The method of claim 5 wherein the aqueous system is that of a cooling water system.
Claim 10
Dependent Claim
18 words
The method of claim 5 wherein the aqueous system is that of a pulp and paper mill system.
