Methods of Manufacturing · 2 件

Sulfur trioxide produced by the contact process is absorbed in concentrated sulfuric acid.

Oleum is produced industrially in contact plants, where sulfur trioxide- containing gases are passed through a special oleum tower. In a double-absorption plant this is located upstream from the intermediate absorber; otherwise it is upstream from the final absorber. ... Sulfur trioxide-containing gas enters the oleum-irrigated packed tower at ca. 200 °C. Depending on the desired product concentration, the tower is irrigated with 22% or 35% oleum at a temperature of ca. 40 - 50 °C. Oleum of higher concentration leaves the tower at ca. 60 - 80 °C. It is adjusted to the desired final oleum concentration by addition of concentrated sulfuric acid from the intermediate or final absorber of the contact plant, and is then cooled in special coolers. Product is withdrawn from the oleum circuit downstream from the cooler. Oleum of higher concentrations (e.g., 60 - 65%) is obtained by mixing 20 - 36% oleum with pure sulfur trioxide.

説明Fuming sulfuric acid is also called oleum, which is a trade name. It is a heavy, oily liquid, colorless to dark brown depending on purity, and fumes strongly in moist air and is extremely hygroscopic. Fuming sulfuric acid is a solution of sulfur trioxide in sulfuric acid. Sulfur trioxide is forced into solution with sulfuric acid to the point that the solution cannot hold any more. As soon as the solution is exposed to air, the fuming begins, forming dense vapor clouds. It is violently water reactive, as are most acids. Oleum is also a strong irritant to tissue. The four-digit UN identification number is 1831.

使用In manufacture of fertilizers, explosives, dyestuffs, other acids, parchment paper, glue, purification of petroleum, pickling of metal.

一般的な説明Thick fuming yellow liquid. Density 16.5 lb / gal. Very toxic by inhalation. Corrosive to metals and tissue, quickly causing severe burns. Used to make chemicals, dyes, explosives and in petroleum refining.
