Abstract
This process for the preparation of isobornyl (meth)acrylate by reaction of (meth)acrylic acid with camphene consists in blending the reactants in a blending tank and in placing the mixture in contact with the catalyst in a cartridge which is separate from the blending tank. Single figure.
Claims11
In a process for the preparation of isobornyl (meth)acrylate of the formula ##STR3## in which R is a hydrogen atom or a methyl radical, by reaction of (meth)acrylic acid, of the formula ##STR4## of the formula ##STR5## with camphene in the presence of, as a catalyst, an acidic cationic ion exchange resin, the improvement comprising blending (meth)acrylic acid and camphene in a blending tank in order to obtain a mixture and placing the mixture in contact with the catalyst in a cartridge which is separate from the blending tank.
In a process for the preparation of isobornyl (meth)acrylate of formula ##STR6## in which R is a hydrogen atom or a methyl radical, by reaction of (meth)acrylic acid, of the formula ##STR7## of the formula ##STR8## with camphene in the presence of, as a catalyst, an acidic cationic ion exchange resin, forming a mixture of the (meth)acrylic acid and camphene starting materials and passing said mixture through a cartridge containing said resin in order to convert a partial amount of the starting materials to isobornyl (meth)acrylate, subjecting the resultant reaction mixture to heat exchange, then passing the resultant heat exchanged reaction mixture back to said cartridge to convert another partial amount of the starting materials and repeating the resultant cycle a plurality of times.
