Abstract

The water‐soluble acids obtained by the oxidation of the Melton‐field vitrain at a copper anode, have been subjected to a detailed examination with the object of isolating recognizable products. Chromatographic methods of separation proved unsuccessful. The two fractions obtained after separation into soluble and insoluble ammonium salts were converted to the methyl esters and distilled in vacuo. Oxalic acid, mellitic acid, hemimellitic acid and __iso‐__phthalic acid were isolated, but only oxalic acid was obtained in appreciable amounts. The bulk of the water‐soluble acids thus remain uncharacterized. Decarboxylation, however, yielded benzo‐phenone, diphenyl and benzene which arc typical products from the decarboxylation of benzene carboxylic acids. In general, these acids appear to be similar in nature to the acids obtained by alkaline permanganate oxidation of coal, the greater portion of which has never been characterized.

The vacuum desorption of water from brown coal has been investigated at temperatures from 30°C to 120°C. The amount of water which can be desorbed after prolonged evacuation to a constant weight increases with increasing temperature, and is accompanied by the evolution of carbon dioxide at temperatu
