More interesting are some of the more speciality uses of the compound, which are less significant in volume but are possibly more important for the rest of the industry. There are many important large-scale industrial syntheses that use sulphuric acid, for example the manufacture of ethanol from ethane, one of the routes to titanium dioxide (a white pigment important to the paint industry), the production of hydrofluoric acid from calcium fluoride (the ultimate source of about 70% of all the fluorine in fluorinated compounds), the production of aluminum sulphate (an omportant water-treatment chemical), the production of sulohonated surfactants(detergents and many other applications). Many uses are based on the fact that sulphuric acid represents a cheap source of protons. For example, the manufacture of hydrofluoric acid from fluoride-containing minerals involves mixing them with concentrated sulphuric acid in a rotating kiln the fluoride protonated to hydrogen fluoride by the acid and
