This compound is widely used as an analgesic, in fact it was the first to be used for this purpose, its anesthetic use has turned it into a recreational drug, it has a wide use as a solvent for fats, oils, waxes, resins, gums, perfumes, alkaloids, cellulose acetate, cellulose nitrate, hydrocarbons and dyes.
Sulfuric ether can be obtained as a by-product in the production of ethanol through hydration in the vapor phase of ethylene, using phosphoric acid as a catalyst. Or by dehydrating ethanol with sulfuric acid at 140 oC
