Abstract
In the present invention aliphatic aldehydes are condensed to form .alpha.,.beta.-unsaturated aldehydes by use of a heterogeneous catalyst. Such process uses an anatase titanium dioxide catalyst in a fixed bed process under mild temperature conditions to yield high conversions and high yields, and which also eliminates the catalyst removal steps required by conventional processes.
