Product description (H2SO4)
Colorless, nonflammable liquid.
Sulfuric acid techn. 96 % and sulfure acid monohydrate have an oily consistency and are very hygroscopic.
Production by oxidation of sulfur or by cleavage of contaminated sulfuric acids.
|
Packaging/ Delivery
Transport by road tank truck, railroad tank car or ship. Marketed in Europe only.
Properties
Sulfuric acid is a strong acid which is miscible with water in all proportions. On mixing with water a great deal of heat evolved which may cause splashing of the acid. For that reason sulfuric acid should be added to water only slowly with constant stirring and monitoring of the temperature. It has a dehydrating (desiccating) effect with carbonization on many organic substances.
