A PRCESS RELATING TO THE PRODUCTION OF BETA NAPHTHALDEHYDE FROM BETA-METHYLNAPHTHALENE A CONSTITUENT OF TAR OILS OBTAINED BY BOTH HIGH AND LOW TEMPERATURE CARBONIZATION,.

摘要

A process for the production of beta-naphthaldehyde and phthalic anhydride by the oxidation of beta-methyl naphthalene, characterized in that the oxidation is carried out in the vapour phase with air and steam in the presence of ferric vaoadate on granoular pumice catalysts.
