A continuous process and system for preparing branched aldehydes by reacting aldehyde with an acid polymeric catalyst absent any metal from Group VIII to produce a product having about 10 to 99.99% by weight branched unsaturated aldehyde and at least 92% selectivity of reaction to the branched aldehyde and recycling a portion of the product.

Catalyst and process to produce branched unsaturated aldehydes

A method of making a heterogeneous catalyst, the catalyst produced therefrom, and the use of the catalyst, comprising mixing a dried ion exchange resin with a solution of a ketone and a metal, swelling the ion exchange resin, distributing the metal in the resin, and transforming without reducing agents the metal to zero valent at a temperature below 120&#xb0; C.

Method for making heterogenous catalysts

A polymeric catalyst, and methods of using the catalyst, comprising at least one of a monosulfonated ion exchange resin, monosulfonated gel, and macroreticular resin having a particle size of less than 560 &#x3bc;m and metal impregnated within the resin, where the metal is palladium, platinum, iridium, rhodium, ruthenium, copper, gold, and/or silver.

Multireaction bifunctional polymeric catalyst

A crosslinked polymeric bead comprising a polymer having from 0.5 mole percent to 2 mole percent crosslinker. The bead has a diameter no greater than 200 &#x3bc;m, no void spaces having a diameter greater than 5 &#x3bc;m, and less than 5 weight percent of organic extractables.
