PROCESS FOR THE PREPARATION OF SQUARIC ACID

A process for producing squaric acid comprises reacting hexachlorocyclobutene, or its mixtures with hexachlorobutadiene, with 96-100% sulfuric acid, at 80 DEG -150 DEG C., and adding at least the stoichiometric amount of water required for the hydrolysis, while maintaining the acid concentration bet...
