Abstract
Preparation of vinyl carboxylates by the reaction of a carboxylic acid with acetylene in the presence of a platinum metal complex catalyst, which contains as ligands carbon monoxide or a nitrile (I), a tertiary nitrogen base (II), a tertiary phosphorus compound (III) having C-organic and/or O-organic radicals or mixtures of said compounds. The end products serve as monomers or comonomers for polymer dispersions.
Claims8
A process for the preparation of vinyl carboxylates by the reaction of a carboxylic acid with acetylene in the presence of a platinum metal complex catalyst, wherein a complex of a platinum metal is used as platinum metal complex catalyst, which contains as ligands carbon monoxide, a monovalent or polyvalent nitrile (I), a monovalent or polyvalent nitrogen base (II), a monovalent or polyvalent tertiary phosphorus compound (III) having C-organic and/or O-organic radicals, or mixtures of said compounds.
