Useful:

• Uses: As flux in analysis of ores and siliceous Compounds. Potassium hydrogen sulfate is used in the conversion of tartrates to bitartrates in wine. It serves as a disintegrating agent in analytical chemistry and as an intermediate in the preparation of potassium persulfate by electrolysis. It is also employed in the manufacturing of fertilizers. Potassium bisulfate may be used:As a catalyst for the preparation of butyl paraben from p-hydroxybenzoic acid and n-butyl alcohol.As a promoter for the synthesis of 3,4-dihydropyrimidin-2(1H)-one derivatives via Biginelli reaction in ethylene glycol.As an acid catalyst for the synthesis of ethyl tert-butyl ether (ETBE) from ethanol and tert-butyl alcohol via reactive distillation.As a dehydrating agent for the synthesis of pyruvic acid from tartaric acid.
