Preparation of diester of (meth)acrylic acid from epoxide |
| abstract |
The present application relates to a method of preparing a (meth)acrylic acid diester by reacting (meth)acrylic anhydride with an epoxide in the presence of a catalyst system comprising a first and/or second catalyst combined with a cocatalyst. The first catalyst is a halide of Mg or trifluoromethanesulfonate of a rare earth element; The second catalyst is the Cr(III) salt; The cocatalyst is a tertiary amine, a quaternary ammonium salt, a tertiary phosphine or a quaternary phosphonium salt. |
