Sulphuric acid H2SO4 is clear, colorless, oily, odorless liquid. It is a strong dibasic acid; fully miscible in water. Sulphuric acid dissolves in water with liberation of heat.
Uses of Sulfuric Acid Technical Grade
The main use of sulfuric acid is in fertilizer production such as superphosphate and ammonium sulphate;
In orthophosphoric acid making. Orthophosphoric acid is then used in fertilizers and detergents(trisodium phosphate)
Preparation: Ca3F(PO4)3 +5H2SO4+10H2O>5CaSP4 *2H2O+HF+3H3PO4
To produce Aluminium sulfate AL2(SO4)4 which is used in water treatment to produce Aluminium hydroxide(coagulant);
As a component of nitrating mixture in making nitro-substituted organic compounds(dyestuff, pharmaceuticals precursors, explosives):
As a dehydrating agent in chemical processes such as diethyl ether preparation, esterification reactions and so on;
To produce sulfonated organic compounds used as pharmaceuticals. dyes intermediates and others:
As a catalyst for electrophilic reactions in industry and laboratory( i.e. for the reaction of isobutene with isobutylene to give isooctane and to caprolactam):
In the purification of petroleum to remove impurities out of gasoline and other refinery products:
In picking of metals, electroplating baths, nonferrous metallurgy;
As an electrolyte in lead-acid batteries;
Concentrated acid is used as a general dehydrating agent for gases;
47.5kgs jerry cans and bulk in tankers.
