Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
140 words
AN APPARATUS FOR CONDUCTING CONTROLLED REACTIONS OF FLUID REACTANTS WHICH COMPRISES A REACTION VESSEL HAVING A REACTION CHAMBER ENCLOSED BY A CONCAVE WALL AND AT LEAST ONE OTHER WALL, MULTIPLE REACTANT INLETS, AND AN EXIT MEANS, SAID CONCAVE WALL ENCOMPASSING SAID EXIT MEANS, SAID EXIT MEANS BEING CENTRALLY POSITIONED IN RELATION TO SAID OTHER WALL AND COMMUNICATING WITH SAID REACTION CHAMBER, SAID REACTANT INLETS COMMUNICATING WITH SAID REACTION CHAMBER AT POSITIONS SPACED FROM SAID CONCAVE WALL WHICH ARE ALSO SPACED FROM AND SUBSTANTIALLY CIRCUMSCRIBE A MAJOR AXIS OF SAID EXIT MEANS, AND WHICH ARE ALIGNED TO IMPART TO FLUID REACTANTS ISSUING THEREFROM INTO SAID REACTION CHAMBER A COCURRENT SWIRLING MOTION, WHEREBY REACTANTS ENTER SAID REACTION CHAMBER, SWIRL PAST SAID REACTANT INLETS AND TOWARD SAID EXIT MEANS WHILE REACTING AND ARE CONTINUOUSLY ADMIXED WITH INCOMING REACTANTS BEFORE LEAVING SAID REACTION CHAMBER.
Claim 2
Independent Claim

Claim 3
Dependent Claim
142 words
A PROCESS FOR OXIDIZING A C1 TO C25 ORGANIC COMPOUND, WHICH COMPRISES MIXING SAID COMPOUND WITH AN OXYGEN-CONTAINING GAS,CONTINUOUSLY PASSING THE RESULTING REACTANT MIXTURE UNDER PRESSURE THROUGH MULTIPLE INLETS AT A LINEAR GAS VELOCITY OF ABOUT 10 TO 5000 FT./SECOND AND AT A TEMPERATURE OF ABOUT 250*F. TO 800*F. INTO A REACTION ZONE A PORTION OF WHICH IS HEATED TO A TEMPERATURE ABOVE THE AUTOIGNITION TEMPERATURE OF SAID REACTANT MIXTURE UNTIL AFTER SAID REACTION IS INITIATED, REACTING SAID COMPOUND WITH SAID GAS, SWIRLING SAID REACTION MIXTURE AND THE RESULTING REACTION PRODUCTS IN A GENERALLY CONCURRENT MOVEMENT PAST SAID INLETS THROUGH THE MOTION IMPARTED TO SAID REACTANT MIXTURE AND SAID REACTION PRODUCTS BY THE CONTINUOUS INCOMING PASSAGE OF SAID REACTANT MIXTURE THROUGH SAID INLETS, AND PASSING SAID REACTION PRODUCTS FROM SAID REACTION ZONE AFTER A RESIDENCE THEREIN OF ABOUT 0.01 TO 10 SECONDS.
