Disclosed are novel species of cellulose acetate butyrates and propionates that have significant surface activity. The cellulose acetate butyrate/propionate contains 9-16 wt. % butyryl or propionyl, 6-11 wt. % acetyl, and 12-15 wt. % hydroxyl.

Mixed cellulose esters

Disclosed are catalyst compositions comprised of chemically-mixed, copper-titanium oxides and the use of such catalyst compositions in the hydrogenation of certain esters to obtain the alcohol corresponding to the acid residue of the ester.

Catalyst composition for the hydrogenation of carboxylic acid esters

Catalyst compositions and the use thereof in the hydrogenation of

Substituted terephthalaldehydes are produced by the vapor phase oxidation of similarly substituted p-xylenes in the presence of a catalyst mixture of tungsten in the form of an oxide or silicotungstic acid, molybdenum in the form of an oxide and optionally bismuth in the form of an oxide.

Oxidation of substituted p-xylenes to substituted terephthalaldehydes

Terephthalaldehyde is produced by the vapor phase oxidation of p-xylene in the presence of a catalyst mixture of tungsten in the form of an oxide or silicotungstic acid, molybdenum in the form of an oxide and bismuth in the form of an oxide.
