Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
57 words
A PROCESS FOR PREPARING ACETONE WHICH COMPRISES REACTING PROPYLENE WITH AN OXIDIZING AGENT ESSENTIALLY CONSISTING OF AN AQUEOUS SUSPENSION OF MERCURIC NITRATE AND FERRIC NITRATE TO FORM A COMPLEX BETWEEN PROPYLENE AND MERCURIC NITRATE, DECOMPOSING SAID COMPLEX BY HEAT AND RECOVERING ACETONE PRODUCED THEREBY, THE MOLAR RATIO OF FERRIC NITRATE TO MERCURIC NITRATE BEING ABOVE ABOUT 0.1.
Claim 2
Dependent Claim
57 words
A PROCESS FOR PREPARING ACETONE WHICH COMPRISES REACTING PROPYLENE WITH AN OXIDIZING AGENT ESSENTIALLY CONSISTING OF AN AQUEOUS SUSPENSION OF MERCURIC NITRATE AND FERRIC NITRATE TO FORM A COMPLEX BETWEEN PROPYLENE AND MERCURIC NITRATE, DECOMPOSING SAID COMPLEX BY HEAT AND RECOVERING ACETONE PRODUCED THEREBY, THE MOLAR RATIO OF FERRIC NITRATE TO MERCURIC NITRATE BEING ABOVE ABOUT 0.1.
Claim 3
Dependent Claim
66 words
A PROCESS AS DEFINED IN CLAIM 1, WHEREIN PROPYLENE IS INITIALLY BROUGHT INTO CONTACT WITH THE OXIDIZING AGENT TO FORM A COMPLEX COMPOUND OF MERCURIC NITRATE AND PROPYLENE AT A TEMPERATURE IN THE RANGE FROM 0*C. TO 50* C. AND THEREAFTER THE SAID OXIDIZING AGENT IS HEATED TO A TEMPERATURE RANGING FROM 50*C. TO 180*C. WHERE DECOMPOSITION OF THE COMPLEX COMPOUND READILY PROCEEDS TO YIELD ACETONE.
