Claim 1
Independent Claim
100 words
A PROCESS FOR THE PRODUCTIN OF 3-CHLOROBUTANONE2 IN ADDITION TO BUTANONE FROM A N-BUTYLENE, WHICH COMPRISES INTIMATELY CONTACTING N-BUTYLENE AT A TEMPERATURE BETWEEN 95 AND 180*C. WITH AN AQUEOUS SOLUTION OF COPPER CHLORIDE AND PALLADIUM CHLORIDE CONTAINING 0.8 TO 2 MOLS OF COPPER AND 0.0005 TO 0.05 MOL OF PALLADIUM PER LITER, THE OXIDATION POTENTIAL OF SAID SOLUTION BEING MAINTAINED AT A VALUE OVER 330 MILLIVOLTS MEASURED AT 80*C. AGAINST A NORMAL CALOMEL ELECTRRODE BY OXIDATION WITH OXYGEN, SEPARATING THE CRUDE KETONES PRODUCED FROM SUCH AQUEOUS SOLUTION AND SEPARATING THE BUTANONE FROM THE 3-CHLOROBUTANONE-2 IN THE CRUDE KETONES BY DISTILLATION.
