Montecatini was an important Italian chemicals company founded in 1888. It was called: quasi-monopolost of the Italian chemical Industry in the time between World War I and the end of World War II. Problems led to a merger with the Edison company in 1966 forming the Montedison company.
The company was founded as small mining business in Montecatini Val di Cecina operating a copper pyrite mine in 1888. The production increased and a shift from copper ore production to pyrite production as starting material for sulfuric acid production when Guido Donegani was made director in 1910.
Large amounts of sulfuric acid are used for the production of superphosphate fertilizers and therefore Montecatini expanded into this business. by 1920 the company acquired the two largest phosphate fertilizer producers Unione Concimi and Colla e Concimi. The company became dominant in chemical industry of Italy during the time of Fascist Italy.
