STEAMING SULPHURIC ACID (OLEUM)

Steaming Sulphuric Acid, also known as Oleum, produced by Marchi Industriale S.p.A. is obtained through a modern contact catalytic process which uses pure sulphur in its elementary state as raw material. 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 degree of purity which is very appreciated by the most important leaders of the production of detergents, drugs or other industrial products.

IDENTIFICATION OF THE PRODUCT

Chemical name: Steaming Sulphuric Acid (Oleum)
EC Index no. 016-019-00-2

PROPERTIES

Steaming Sulphuric Acid is supplied in aqueous solution with two typical concentrations: 104.5% and 105.5% H2SO4 which correspond to concentrations equal to 20% and 24.4% SO3. It is a synthethised product with a high degree of purity is underlined by its very limited content of pollutants.

USES

It has widely varied uses. For example:
• Raw material in different industrial chemical processes;
• Raw material in processes of sulfonation in the making of synthetic detergents;
• Raw material in the production of explosives;
• Synthesis of active ingredients for drugs.

TRANSIT PACKING, STORAGE, HANDLING

Steaming 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 of 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.
