Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
82 words
AN IMPROVED PROCESS FOR THE MANUFACTURE OF POLYMER GASOLINE WHICH COMPRISES ADDING BORON TRIFLUORIDE TO LIQUID PHOSPHORIC ACID OF ABOUT 85 TO 100% CONCENTRATION AT A TEMPERATURE BELOW ABOUT 50*F. UNTIL SAID ACID HAS REACTED WITH A SUBSTANTIALLY EQUAL MOLAR QUANTITY OF BORON TRIFLUORIDE TO FORM A LIQUID COMPLEX, PASSING SAID COMPLEX TO A POLYMERIZATION ZONE, INTRODUCING C3-C4 OLEFINS IN CONTACT WITH SAID COMPLEX UNDER POLYMERIZATION CONDITIONS, AND RECOVERING FROM SAID POLYMERIZATION ZONE A HYDROCARBON FRACTION BOILING IN THE GASOLINE BOILING RANGE.
