A PROCESS TO PRODUCE POLYOLS

A PROCESS FOR PRODUCING OLEOCHEMICAL POLYOLS COMPRISES THE STEPS OF EPOXIDIZING UNSATURATED OIL USING AN ORGANIC ACID TOGETHER WITH OXYGENATED WATER OR A PER-ACID TO OBTAIN EPOXIDIZED OIL; WASHING THE EPOXIDIZED OIL WITH SALT WATER TO REMOVE UNUSED ORGANIC ACID TOGETHER WITH OXYGENATED WATER OR A PE...

Zusammenfassung:A PROCESS FOR PRODUCING OLEOCHEMICAL POLYOLS COMPRISES THE STEPS OF EPOXIDIZING UNSATURATED OIL USING AN ORGANIC ACID TOGETHER WITH OXYGENATED WATER OR A PER-ACID TO OBTAIN EPOXIDIZED OIL; WASHING THE EPOXIDIZED OIL WITH SALT WATER TO REMOVE UNUSED ORGANIC ACID TOGETHER WITH OXYGENATED WATER OR A PER-ACID; NEUTRALIZING ACIDIC CONDITION OF THE WASHED EPOXIDIZED OIL WITH A BASE; WASHING THE NEUTRALIZED EPOXIDIZED OIL WITH A SALT SOLUTION UNTIL THE PH OF THE NEUTRALIZED EPOXIDIZED OIL REACHING 6.5 TO 7.5 TO REMOVED THE BASE RESIDUE; DRYING THE WASHED NEUTRALIZED EPOXIDIZED OIL UNDER VACUUM; AND REACTING THE WASHED NEUTRALIZED DRIED EPOXIDIZED OIL WITH POLYHYDRIC ALCOHOL IN THE PRESENCE OF BORON TRIFLUORIDE-DIETHYLETHER COMPLEX TO PRODUCE THE OLEOCHEMICAL POLYOLS. THE OLEOCHEMICAL POLYOLS ARE THEN SUBJECTED TO THE SAME WASHING, NEUTRALIZING, WASHING AND DRYING PROCESS AS IN PREPARING THE WASHED NEUTRALIZED DRIED EPOXIDIZED OIL.
