COMMERCIAL SULPHURIC ACID

Commercial Sulphuric Acid produced by Marchi Industriale S.p.A. is obtained through a modern contact catalytic process which uses pure sulphur in its elementary state. If this type of productive process is associated with the necessary storage procedures and with controls either on the finite product, on raw materials or on production intermediates, it assures a good degree of purity which is appreciated by a huge number of industries demanding this type of product for their workings.

IDENTIFICATION OF THE PRODUCT

Chemical name: Concentrated Sulphuric Acid
EC Index no. 016-020-00-8
EINECS no. 231-639-5
CAS no. 7664-96-9

PROPERTIES

Commercial Sulphuric Acid is supplied in aqueous solution with different concentrations ranging from 99% to 20% H2SO4 as customers may require. It is a synthethised acid with an good degree of purity and it can meet users' requires in a large number of uses.

USES

It has widely varied uses and plays some part in the production of nearly all manufactured chemical. For example:
• Reagent for the food industry;
• Raw material in different industrial chemical processes;
• Raw material in the making of synthetic detergents;
• Reagent for the paper industry;
• Urban and industrial waste water treatment;
• Production of fertilizers, drugs, pigments, plastic materials, artificial fibres and explosives.

TRANSIT PACKING, STORAGE, HANDLING

Commercial Sulphuric Acid is provided by tank trucks with a capacity of 28 tons.
All equipment being in contact with the product, from the storage to the dosage, have to be made of stainless alloy or an adequate antiacid material. For the handling and any other information about users' health, look at the Safety Form which have to be requested during the first order agreement.
