8.used for phenol by alkali fusion system, but also for making between benzodiazepines, etc., often used as a catalyst in the esterification and dehydration reactionPurpose is used as the experimental reagent, catalyst, also used in organic synthesis, and phenol manufactureUse benzene sulfonic acid used in oil field water injection, can remove congestion, increase the formation permeability of formation.Benzene sulfonic acid as acid acidification of injection Wells, the characteristics of slow and carbonate reaction is, and the greater the concentration, reaction rate slower, acidification profound formation, compared with hydrochloric acid, benzene sulfonic acid (and mixed aryl sulfonic acid) the period of validity, corrosive small, the use of safe.Benzene sulfonic acid was used as the esterification of curing agent and dehydration reaction catalyst and foundry industry.Use inspection ammonium salt and potash.The determination of zinc.In organic synthesis.Manufacture of phenol and resorcinol.The catalyst.Used as dehydration catalyst, resin, curing agent, and electroplating additives, also can be used as dye intermediates.
