Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
79 words
A METHOD OF CONTROLLING THE PROLIFERATION OF DELETERIOUS MICROORGANISMS SELECTED FROM THE GROUP CONSISTING OF BACTERIA AND ALGAE IN AN AQUEOUS SYSTEM, WHICH COMPRISES APPLYING TO SAID MICROOGANISMS A BACTERIACIDALLY OR ALAECIDALLY EFFECTIVE AMOUNT OF A CONDENSATION PRODUCT FORMED BY MIXING 1,4BISIDIMETHYLAMINO-2-BUTENE DISSOLVED IN A SOLVENT WITH 1,4DIHALO-2-BUTENE AT ROOM TEMPERATURE WHEREBY AN EXOTHERMIC REACTION IS OBTAINED CAUSING THE TEMPERATURE OF THE MIXTURE TO RISE, THEN MAINTAINING THE MIXTURE AT NO HIGHER THAN REFLUX TEMPERATURE UNTIL THE REACTION COMPLETE,
Claim 2
Independent Claim
79 words
A METHOD OF CONTROLLING THE PROLIFERATION OF DELETERIOUS MICROORGANISMS SELECTED FROM THE GROUP CONSISTING OF BACTERIA AND ALGAE IN AN AQUEOUS SYSTEM, WHICH COMPRISES APPLYING TO SAID MICROOGANISMS A BACTERIACIDALLY OR ALAECIDALLY EFFECTIVE AMOUNT OF A CONDENSATION PRODUCT FORMED BY MIXING 1,4BISIDIMETHYLAMINO-2-BUTENE DISSOLVED IN A SOLVENT WITH 1,4DIHALO-2-BUTENE AT ROOM TEMPERATURE WHEREBY AN EXOTHERMIC REACTION IS OBTAINED CAUSING THE TEMPERATURE OF THE MIXTURE TO RISE, THEN MAINTAINING THE MIXTURE AT NO HIGHER THAN REFLUX TEMPERATURE UNTIL THE REACTION COMPLETE,
Claim 3
Dependent Claim
10 words
The method of claim 1 wherein the dihalo is dichloro.
Claim 4
Dependent Claim
10 words
The method of claim 1 wherein the dihalo is dibromo.
Claim 5
Dependent Claim
12 words
The method of claim 1 wherein the aqueous media is recirculated water.
Claim 6
Dependent Claim
84 words
An aqueous composition containing, as a biocidal agent, the condensation product formed by mixing 1,4-bis-dimethylamino-2-butene dissolved in a solvent with 1,4-dihalo-2-butene at room temperature whereby an exothermic reaction is Obtained causing the temperature of the mixture to rise, then maintaining the mixture at no higher than reflux temperature until the reaction is complete, wherein these reactants are in a molar proportion of between about about 1:3 and about 3:1 relative to each other, said agent being present in a bacteriacidally or algaecidally effective amount.
Claim 7
Dependent Claim
84 words
An aqueous composition containing, as a biocidal agent, the condensation product formed by mixing 1,4-bis-dimethylamino-2-butene dissolved in a solvent with 1,4-dihalo-2-butene at room temperature whereby an exothermic reaction is Obtained causing the temperature of the mixture to rise, then maintaining the mixture at no higher than reflux temperature until the reaction is complete, wherein these reactants are in a molar proportion of between about about 1:3 and about 3:1 relative to each other, said agent being present in a bacteriacidally or algaecidally effective amount.
Claim 8
Dependent Claim
12 words
The composition of claim 5 wherein said aqueous media comprises recirculating water.
Claim 9
Dependent Claim
15 words
The composition of claim 5 wherein said composition is an aqueous emulsion containing non-ionic emulsifiers.
Claim 10
Dependent Claim
15 words
The composition of claim 5 wherein said composition is a hand cream or baby lotion.
