description The present invention relates to a process for preparing ethylene glycol dimethacrylate, which comprises transesterification of ethylene glycol with an ester of methacrylic acid in the presence of catalysts, wherein a combination comprising lithium amide (LiNH2) and lithium chloride (LiCl) is used as catalyst. The process of the invention makes it possible to prepare ethylene glycol dimethacrylate particularly inexpensively and in a very high purity.
