Marchi Industriale S.p.A.'s Sulphuric Acid for Accumulators is obtained by a modern contact catalytic process, which uses pure sulphur in elemental form as raw material. This type of production process, combined with adequate arrangements for storage, with checks on both the finished product, on raw materials, and on intermediate production, ensure a high degree of purity appreciated by all leading companies in the production of accumulators.


Chemical Name: Concentrated Sulphuric Acid

EC Index no. 016-020-00-8

EINECS no. 231-639-5

CAS no. 7664-96-9


Marchi Industriale S.p.A.'s Sulphuric Acid for Accumulators is supplied in aqueous solution in two typical concentrations: 96% and 99% H2SO4. It's a synthesis acid with a high degree of purity, emphasised by a very limited content of metals, in particular iron, manganese, vanadium, nickel and chromium.
