ABSTRACT The invention is concerned with a process for producing aldehydes and, more specifically a process employing a vapor phase reaction in the presence of a molten nitrate salt catalyst. An alkylaromatic compound having from 7 to 22 carbon atomes per molecule, or mixture thereof, is reacted with an oxygen-containing gas, the alkylaromatic compound and the oxygen-containing gas being gaseous reactants. The reaction is carried out by contacting the gaseous reactants with a bath, stream, spray or mist of at least one molten nitrate salt catalyst, the catalyst being present in an amount sufficient to absorb any heat generated during the reaction while maintaining an essentially constant reaction temperature, the reaction being conducted at a reaction temperature of between about 135°C and about 600°C and a reaction pressure of between about 1 and about 50 atmospheres to produce the aldehyde or mixture of aldehydes.
