PREPARATION OF METALLIC DIHYDROXYBENZENEDISULFONATES

Metallic dihydroxybenzenedisulfonates are prepared, preferably from alkaline metals, from corresponding dihydroxybenzenedisulfonic acids, by reacting the dihydroxybenzenedisulfonic acid present in a sulfuric medium with an adequate amount of a salt including a sulfate or hydrogenosulfate anion.
