Method of producing polyoleftnic

Claim 1

THE METHOD OF OBTAINING A SYNTHETIC DRYING OIL HAVING AN AVERAGE MOLECULAR WEIGHT OF AT LEAST ABOUT 200, AN IODINE NUMBER IN THE RANGE OF ABOUT 400 TO 600 AND A MALEIC ANHYDRIDE VALUE OF AT LEAST 250, WHICH METHOD COMPRISES CONTACTING A HYDROCARBON CHARGING STOCK WHICH IS SUBSTANTIALLY FREE FROM AROMATIC HYDROCARBONS WITH HYDROGEN FLUORIDE AT A TEMPERATURE IN THE RANGE OF 250* TO 450* F. UNDER A PRESSURE SUFFICIENT TO MAINTAIN LIQUID PHASE CONDITIONS WITH AN HF TO OIL RATIO IN THE RANGE OF .1:1TO 5:1 AND WITH A CONTACT TIME IN THE RANGE OF ABOUT 5 TO 30 MINUTES, COOLING THE CONTACTED MATERIALS AND SEPARATING SAID MATERIALS INTO A SATURATED OIL PHASE CONTAINING ONLY A SMALL AMOUNT OF DISSOLVED HF AND AN HF PHASE COMPOSED CHIEFLY OF FREE HF BUT CONTAINING HYDROGEN FLUORIDE-HYDROCARBON COMPLEX IN SOLUTION, STRIPPING SAID FREE HF FROM THE HYDROGEN FLUORIDE-HYDROCARBON COMPLEX IN THE HF PHASE AT A TEMPERATURE IN THE RANGE OF ABOUT 100 TO 300* F. AND UNDER SUFFICIENT PRESSURE TO LEAVE AT LEAST ABOUT ONE MOLECULE, BUT NOT MORE THAN 2 MOLECULES, OF HF PER DOUBLE BOND IN THE HYROCARBON COMPONENT OF THE COMPLEX IS AVOIDED IN THE STRIPPING TION OF SAID COMPLEX IS AVOIDED IN THE STRIPPING STEP BUT SUBSTANTIALLY ALL UNCOMBINED HYDROGEN FLOURIDE IS REMOVED THEREFROM, NEUTRALIZING THE HF COMPLEX CONTAINING AT LEAST ABOUT 1 BUT NOT MORE THAN ABOUT 2 MOLECULES OF HF PER DOUBLE BOND IN THE HYDROCARBON COMPONENT THEREOF BY CONTACTING SAID COMPLEX WITH AN AQUEOUS ALKALINE SOLUTION AT A TEMPERATURE IN THE RANGE OF 30* TO 150* F., SEPARATING THE RESULTING HYDROCARBON AND AQUEOUS PHASES RESPECTIVELY FROM EACH OTHER, TREATING THE HYDROCARBON PHASE TO ELIMATE RESIDUAL AMOUNTS OF HF AND DISTILLING UNDER SUBATMOSPHERIC PRESSURE THE HYDROCARBON PHASE FROM WHICH RESIDUAL HF HAS BEEN REMOVED.D.

Claim 2

THE METHOD OF OBTAINING A SYNTHETIC DRYING OIL HAVING AN AVERAGE MOLECULAR WEIGHT OF AT LEAST ABOUT 200, AN IODINE NUMBER IN THE RANGE OF ABOUT 400 TO 600 AND A MALEIC ANHYDRIDE VALUE OF AT LEAST 250, WHICH METHOD COMPRISES CONTACTING A HYDROCARBON CHARGING STOCK WHICH IS SUBSTANTIALLY FREE FROM AROMATIC HYDROCARBONS WITH HYDROGEN FLUORIDE AT A TEMPERATURE IN THE RANGE OF 250* TO 450* F. UNDER A PRESSURE SUFFICIENT TO MAINTAIN LIQUID PHASE CONDITIONS WITH AN HF TO OIL RATIO IN THE RANGE OF .1:1TO 5:1 AND WITH A CONTACT TIME IN THE RANGE OF ABOUT 5 TO 30 MINUTES, COOLING THE CONTACTED MATERIALS AND SEPARATING SAID MATERIALS INTO A SATURATED OIL PHASE CONTAINING ONLY A SMALL AMOUNT OF DISSOLVED HF AND AN HF PHASE COMPOSED CHIEFLY OF FREE HF BUT CONTAINING HYDROGEN FLUORIDE-HYDROCARBON COMPLEX IN SOLUTION, STRIPPING SAID FREE HF FROM THE HYDROGEN FLUORIDE-HYDROCARBON COMPLEX IN THE HF PHASE AT A TEMPERATURE IN THE RANGE OF ABOUT 100 TO 300* F. AND UNDER SUFFICIENT PRESSURE TO LEAVE AT LEAST ABOUT ONE MOLECULE, BUT NOT MORE THAN 2 MOLECULES, OF HF PER DOUBLE BOND IN THE HYROCARBON COMPONENT OF THE COMPLEX IS AVOIDED IN THE STRIPPING TION OF SAID COMPLEX IS AVOIDED IN THE STRIPPING STEP BUT SUBSTANTIALLY ALL UNCOMBINED HYDROGEN FLOURIDE IS REMOVED THEREFROM, NEUTRALIZING THE HF COMPLEX CONTAINING AT LEAST ABOUT 1 BUT NOT MORE THAN ABOUT 2 MOLECULES OF HF PER DOUBLE BOND IN THE HYDROCARBON COMPONENT THEREOF BY CONTACTING SAID COMPLEX WITH AN AQUEOUS ALKALINE SOLUTION AT A TEMPERATURE IN THE RANGE OF 30* TO 150* F., SEPARATING THE RESULTING HYDROCARBON AND AQUEOUS PHASES RESPECTIVELY FROM EACH OTHER, TREATING THE HYDROCARBON PHASE TO ELIMATE RESIDUAL AMOUNTS OF HF AND DISTILLING UNDER SUBATMOSPHERIC PRESSURE THE HYDROCARBON PHASE FROM WHICH RESIDUAL HF HAS BEEN REMOVED.D.
