Abstract: Unreacted sulfuric acid contained in a disulfonic acid product of an aromatic hydrocarbon that is produced from the reaction of the aromatic hydrocarbon or the mono-sulfonic acid of the aromatic hydrocarbon with a strong sulfonating agent is removed from the disulfonic acid product by reacting the sulfuric acid with additional aromatic hydrocarbon to produce the mono-sulfonic acid of the aromatic compound. The disulfonic acid product of the aromatic hydrocarbon containing sulfuric acid is reacted with the aromatic hydrocarbon at a molar ratio of aromatic hydrocarbon to sulfuric acid in the range of about 0.25 to around 2 and at a temperature in the range of 130.degree. to 200.degree. C. to obviate the need to remove any water formed during the course of the reaction.

Abstract: A linear aryl sulfide/sulfonate polymer having improved thermal stability is provided consisting essentially of units of the formula: ##STR1## wherein n is an integer of from 3 to about 250.

Abstract: Polyalkylbenzene hydroperoxides are prepared from a homogeneous solution at increased rates in the presence of sulfolane from polyalkylbenzenes which are poorly soluble or insoluble in sulfolane by preoxidizing the polyalkylbenzene to an oxidation level of at least 10 percent and less than 55 percent. Then the sulfolane is added and a homogeneous solution is formed and oxidation is continued to produce a hydroperoxide product at increased rates and to excellent conversions.
