Liquid coordination complexes: a new class of Lewis acids as safer alternatives to BF sub(3) in synthesis of polyalphaolefins

Liquid coordination complexes (LCCs) are a new class of liquid Lewis acids, prepared by combining an excess of a metal halide (e.g. GaCl sub(3)) with a basic donor molecule (e.g. amides, amines or phosphines). LCCs were used to catalyse oligomerisation of 1-decene to polyalphaolefins (PAOs). Molecul...

description Liquid coordination complexes (LCCs) are a new class of liquid Lewis acids, prepared by combining an excess of a metal halide (e.g. GaCl sub(3)) with a basic donor molecule (e.g. amides, amines or phosphines). LCCs were used to catalyse oligomerisation of 1-decene to polyalphaolefins (PAOs). Molecular weight distribution and physical properties of the produced oils were compliant with those required for low viscosity synthetic (Group IV) lubricant base oils. Kinematic viscosities at 100 degree C of ca. 4 or 6 cSt were obtained, along with viscosity indexes above 120 and pour points below -57 degree C. In industry, to achieve similar properties, BF sub(3) gas is used as a catalyst. LCCs are proposed as a safer and economically attractive alternative to BF sub(3) gas for the production of polyalphaolefins.
