A process for purifying ethylene cyanohydrin involves incubating an industrial grade ethylene cyanohydrin product with at least one titanium(IV)alkoxide. Ethylene cyanohydrin products with purities of >99% contain less than 0.05% of ethylene glycol (EG), and/or contain a water content of less than 1000 ppm.

Method for the purification of ethylene cyanohydrin

A process prepares glycerol carbonate (meth)acrylate by transesterification of methyl (meth)acrylate with glycerol carbonate, in the presence of a zirconium acetylacetonate catalyst. The catalyst is pretreated with 2% by weight to 25% by weight of water, based on the amount of catalyst.

Process for preparing glycerol carbonate (meth)acrylate

The invention relates to a method for preparing C—H acidic (meth)acrylates and the uses thereof.

Method for preparing C-H acidic (meth)acrylates

The present invention relates to a process for preparing highly pure glyceryl carbonate by transesterifying dialkyl carbonates or cyclic carbonates in the presence of a basic catalyst.

Process for preparing glyceryl carbonate

The invention relates to a method for producing glycerol carbonate methacrylate in the presence of metal-chelate catalysts of the metal ion-1,3-diketonate type.

Method for producing glycerol carbonate methacrylate

The invention relates to a method for transesterifying methyl methacrylate involving catalysis, particularly zirconium acetylacetonate catalysis. The obtained esters of formula (I) are characterized by having an extremely low content of cross-linking agents.
