PROCEDURE FOR HYDROGENATION OF OLEFINS ON THE BASE OF COMPLEX CATALYSTS OF ZR, TI OR HF.

摘要

THE PRESENT INVENTION REFERS TO A CATALYZING COMPOSITION, WHICH INCLUDES AT LEAST: A) A COMPOSITE METALLIC CATION, FORMULA [(A) (B) ML +], WHERE M REPRESENTS TITANIUM, ZIRCONY OR HAFNIUM, YAYB REPRESENTS LIGHTING, STRUCTURE II WHERE R SUB, 1} REPRESENTS INDEPENDENTLY THE SAME OR DIFFERENT HYDROCARBON GROUPS, WHICH OPTIONALLY CONTAIN HETEROATOMOS; AND R SUB, 3} INDEPENDENTLY REPRESENTS THE SAME OR DIFFERENT HYDROCARBON GROUPS, THAT OPTIONALLY CONTAIN HETEROATOMOS, OR A HALIDE; AND WHERE R SUBSTITUTES CAN BE SHARED BETWEEN A AND B TO FORM A BRIDGE; WHERE M IS A WHOLE BETWEEN 0-5; P IS A WHOLE BETWEEN 0-4; AND Q IS A WHOLE BETWEEN 0-3; WHERE L REPRESENTS HYDROGEN OR A HYDROCARBON GROUP, CONTAINING OPTIONALLY HETEROATOMOS; ON THE CONDITION THAT, IF A AND B ARE BOTH LINKS WITH STRUCTURE I OR II, AT LEAST ONE OF M, N, P OR Q IS AT LEAST 1; B) A STABLE ANION, NOT COORDINATED. THE PRESENT INVENTION REFERS ALSO TO A PROCEDURE FOR THE PREPARATION OF A CATALYST COMPOSITION AND A PROCEDURE FOR CATALYTIC HYDROGENATION OF OLEFINS, OLIGOMERS, POLYMERS OR COPOLYMERS.
