Claims17
A process for the manufacture of isobornyl acrylate or isobornyl methacrylate comprising reacting camphene with acrylic acid or methacrylic acid respectively, in the presence of a catalyst comprising a polyphosphomolybdic acid.
A process for the manufacture of isobornyl (meth)acrylate, comprising the steps of:
- (a) reacting camphene with (meth)acrylic acid in the presence of phosphomolybdic acid;
- (b) removing phosphomolybdic acid from the reaction mixture obtained from (a) to form a crude product mixture;
- (c) distilling the crude product mixture (b) to obtain a purified isobornyl (meth)acrylate product.
