The invention relates to a process for preparing N-methyl(meth)acrylamide and to the uses thereof.

Process for preparing N-methyl(meth)acrylamide

The invention relates to a method for preparing keto-functionalized aromatic (meth)acrylates.

Method for preparing keto-functionalized aromatic (meth)acrylates

The invention relates to a process for preparing methacrylic esters of hydroxyl-functional benzophenones and to their use. Methacrylated benzophenones (benzophenone (meth)acrylates) can be prepared in high purity by the process of the invention, in a simple way and in a high yield.

Method for producing methacrylated benzophenones

Isobornyl (meth)acrylate is synthesized by a two-stage one-pot process, wherein isobornyl acetate is converted to isoborneol followed by transesterification with (meth)acrylic acid methyl ester, without isolation of the intermediates or purification of the product.

Method for synthesis and process inhibition of isobornyl (meth)acrylate

The present invention relates to processes for synthesis of isobornyl (meth)acrylate by reacting camphene with (meth)acrylic acid in the presence of sulfuric acid and at least one compound having inhibiting action. Aqueous sulfuric acid with an acid concentration in the range of 65 to 85 wt % is used. Isobornyl (meth)acrylate can advantageously be distilled from a mixture containing sulfuric acid in the presence of 2,6-di-tert-butyl-&agr;-(dialkylamino)-p-cresol.
