PREPARATION OF DIESTERS OF (METH)ACRYLIC ACID FROM EPOXIDES

The application relates to a process for preparing a (meth)acrylic acid diester by reacting a (meth)acrylic acid anhydride with an epoxide in the presence of a catalyst system comprising a first and/or second catalyst in combination with a co-catalyst. The first catalyst is a halide of Mg or a trifl...

More Information
Summary:The application relates to a process for preparing a (meth)acrylic acid diester by reacting a (meth)acrylic acid anhydride with an epoxide in the presence of a catalyst system comprising a first and/or second catalyst in combination with a co-catalyst. The first catalyst is a halide of Mg or a trifluoromethanesulfonate of a rare earth element; the second catalyst is a Cr(lll) salt; and the co- catalyst is a tertiary amine, a quaternary ammonium salt, a tertiary phosphine or a quaternary phosphonium salt. La invención se refiere a un procedimiento de preparación de diésteres a partir de anhídridos de ácidos carboxílicos.
