Dehydrogenation catalyst consisting of the calcined residue of ferric phosphate and lead phosphate

摘要

Lower aliphatic acids, e.g., isobutyric acid, and esters, e.g., methyl isobutyrate, are dehydrogenated in the presence of oxygen and a solid heterogeneous dehydrogenation catalyst at temperatures in the range of from about 250 DEG C. to about 600 DEG C. The catalyst is the calcined residue of the mixed phosphates of iron and lead.
