Abstract
Process for obtaining phthalic acids and formic acid, characterized by starting from the corresponding dialkyl benzene in which one alkyl contains from 1 to 4 carbon atoms, and the other from 2 to 4 carbon atoms, and the carbon atom of each one of the alkyls, directly attached to the ring has at least one hydrogen substituent and, further, by comprising reacting said hydrocarbon with molecular oxygen, in the presence of 0.1 to 10% by weight, approximately of a heavy metal catalyst and to recover or obtain the desired acids; the by-product formic acid being removed, as required, to maintain the concentration of this body in the mixture of less than about 5%.
