ABSTRACT:
A liquid phase co-oxidation process for the production of a benzaldehyde compound having the following structural formula: ##SPC1##
Wherein R is selected from the group of radicals consisting of hydrogen, halogen, methyl, and methoxy comprising admixing a toluene compound having the following structural formula: ##SPC2##
Wherein R is as defined above with an aliphatic saturated aldehyde having 2 to 7 carbon atoms wherein the molar ratio of toluene compound to aldehyde is preferably about 1 to about 25 mols of toluene compound per mol of aldehyde and an oxygen containing gas consisting of carbon, hydrogen, and oxygen atoms and the temperature is in the range of about 50.degree. to about 250.degree.C.
