Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
173 words
A CONTINUOUS PROCESS OF PREPARING DICHLOROCYANURIC ACID WHICH COMPRISES CONTINUOUSLY INTRODUCING AN AQUEOUS SOLUTION OR DISPERSION OF DIPOTASSIUM CYANURATE INTO A REACTION ZONE WHICH IS MAINTAINED AT A TEMPERATURE WITHIN THE RANGE OF JUST ABOVE THE FREEZING POINT OF SAID SOLUTION OR DISPERSION UP TO 50*C., CONTINUOUSLY INTRODUCING CHLORINE INTO SAID SOLUTION OR DISPERSION IN SAID REACTION ZONE IN AN AMOUNT AT LEAST EQUAL TO THE STOICHIOMETRIC AMOUNT NECESSASRY TO REPLACE THE POTASSIUM ATOMS OF SAID CYANURATE WITH CHLORINE ATOMS, CONTINUOUSLY DISPERSING SAID CHLORINE THROUGH SAID SOLUTION OR DISPERSION TO MAINTAIN SAID SOLUTION OR DISPERSION AT A PH OF NOT MORE THAN 4.5, THEREBY FORMING AN AQUEOUS REACTION MIXTURE HAVING A PH OF NOT MORE THAN 4.5 COMPRISING A SLURRY OF DICHLOROCYANURIC ACID, CONTINUOUSLY REMOVING A PORTION OF SAID REACTION MIXTURE FROM SAID REACTION ZONE BEFORE MATERIAL DECOMPOSITION OF THE DICHLOROCYANURIC ACID OCCURS IN SAID REACTION MIXTURE, AND SEPARATING THE DICHLOROCYANURIC ACID FROM THE BULK OF THE AQUEOUS PHASE OF THE REACTION MIXTURE THUS REMOVED BEFORE MATERIAL DECOMPOSITION OF THE DICHLOROCYANURIC ACID OCCURS.

Claim 3
Dependent Claim
163 words
A CONTINUOUS PROCESS OF PREPARING TRICHLOROCYANURIC ACID WHICH COMPRISES CONTINUOUSLY INTRODUCING AN AQUEOUS SOLUTION TRISODIUM CYANURATE INTO A REACTION ZONE WHICH IS MAINTAINED AT A TEMPERATURE WITHIN THE RANGE OF JUST ABOVE THE FREEZING POINT OF THE SOLUTION UP TO 50* C., CONTINUOUSLY INTRODUCING CHLORINE INTO SAID SOLUTION IN SAID REACTION ZONE IN AN AMOUNT AT LEAST EQUAL TO THE STOICHIOMETRIC AMOUNT NECESSARY TO REPLACE THE SODIUM ATOMS OF SAID CYANURATE WITH CHLORINE ATOMS, CONTINUOUSLY DISPERSING SAID CHLORINE THROUGH SAID SOLUTION TO MAINTAIN THE SOLUTION AT A PH BELOW 4.5, THEREBY CONTINUOUSLY FORMING AN AQUEOUS REACTION MIXTURE HAVING A PH BELOW 4.5 CONSISTING ESSENTIALLY OF SODIUM CHLORIDE AND A SLURRY OF TRICHLOROCYANURIC ACID, CONTINUOUSLY REMOVING A PORTION OF SAID REACTION MIXTURE FROM SAID REACTION ZONE BEFORE MATERIAL DECOMPOSITION OF THE TRICHLOROCYANURIC ACID OCCURS IN SAID REACTION MIXTURE, AND SEPARATING THE TRICHLOROCYANURIC ACID FROM THE BULK OF THE AQUEOUS PHASE OF THE REACTION MIXTURE THUS REMOVED BEFORE MATERIAL DECOMPOSITION OF THE TRICHLOROCYANURIC ACID OCCURS.
