Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
140 words
A COMPOSITION ACTIVE FOR CONVERTING AN OLEFIN TO OBTAIN THE PRODUCT OF THE OLEFIN REACTION WHICH, AS DEFINED HEREIN, CAN BE VISUALIZED AS COMPRISING THE REACTION BETWEEN TWO FIRST PAIRS OF CARBON ATOMS, THE TWO CARBON ATOMS OF EACH FIRST PAIR BEING CONNECTED BY AN OLEFINIC DOUBLE BOND, TO FORM TWO NEW PAIRS FROM THE CABON ATOMS OF SAID FIRST PAIRS, THE TWO CARBON ATOMS OF EACH OF SAID NEW PAIRS BEING CONNECTED BY AN OLEFINIC DOUBLE BOND COMPRISING MAGNESIUM OXIDE ADMIXED WITH A SEPARATE DISPROPORTIONATION CATALYST SELECTED FROM THE GROUP CONSISTING OF SILICA GEL OR THORIA PROMOTED BY AN OXIDE OR A COMPOUND CONVERTIBLE TO THE OXIDE BY CALCINATION OF TUNGSTEN OR MOLYBDENUM; SAID MAGNESIUM OXIDE BEING PRESENT IN AN AMOUNT IN THE RANGE OF 0.1 TO 20 PARTS BY WEIGHT PER PART BY WEIGHT OF SAID DISPROPORTIONATION CATALYST.
