Abstract: USEFUL PARTIAL OXIDATION PRODUCTS OF DIALKYLNAPHTHALENES, SUCH AS THE NAPHTHALENEDICARBOXALDEHYDE AND THE NAPHTHALENEDICARBOXYLIC ACID ARE PREPARED BY USING MOLECULAR OXYGEN AND A CATALYTIC AMOUNT OF NITRIC OXIDE OR NITROGEN DIOXIDE, THAT IS SUBSTANTIALLY LESS THAN THE STOICHIOMETRIC AMOUNT OF NITROGEN DIOXIDE NECESSARY TO OXIDIZE THE DIALKYLNAPHTHALENES. THE CATALYST IS A COMBINATION OF 0.01 MOLES TO 0.6 MOLE OF THE NITROGEN OXIDE PER MOLE OF DIALKYLNAPHTHALENE AND 0.1 TO 6 WEIGHT PERCENT OF SELENIUM. THE OXIDATIONS ARE CARRIED AT SUPERATMOSPHERIC PRESSURES IN A CLOSED SYSTEM AT TEMPERATURES OF ABOUT 160275* C. OXYGEN IS ADDED IN AT LEAST THE STOICHIOMETRIC AMOUNT NEEDED FOR THE OXIDATIONS. IN THE TEMPERATURE RANGE OF ABOUT 160-225* C. THE DIALDEHYDE IS THE PREDOMINANT PRODUCT; AT ABOUT 225 TO 275* C. THE DIACID PREDOMINATES.
