CONVERSION OF cis-4-METHYL-1,2,3,6-TETRAHYDROPHTHALIC ANHYDRIDE ON METALLIC CATALYSTS.

The hydrogenating and dehydrogenating properties of platinum, palladium, and nickel deposited on alumina were studied in the vapor-phase conversion of cis-4-methyl-1,2,3,6-tetrahydrophthalic anhydride in a flow-type apparatus. Conversion of 4-MTHPA on platinum and palladium proceeds virtually without destruction of the original molecule. The alumina-palladium catalyst with a palladium content of 2. 0 mass % has the highest activity and selectivity. The yield of 4-MHHPA and 4-MPA at 300 degree is 94. 5% on the converted feed, with 94. 8% conversion. Alumina-nickel catalysts exhibit mainly isomerization and dehydrogenation activity. Increase of the content of the active component in the catalyst intensifies its dehydrogenating action. Introduction of alkaline additives weakens the dehydrogenating and cracking functions.
