Product Description
Specifications
Sulfuric acid (chemical formula: H2SO4), the most important oxyacid of sulfur. Anhydrous sulfuric acid is a colorless oily liquid, which crystallizes at 10.36 ℃. Its aqueous solutions of various concentrations are usually used and are obtained by tower method and contact method. The former is crude dilute sulfuric acid with a mass fraction of about 75%. The latter can obtain concentrated sulfuric acid with a mass fraction of 98.3, boiling point of 338 ℃, and relative density of 1.84
Basic information
Application areas
Sulfuric acid is one of the most active binary inorganic strong acid, can react with most metals. High concentrations of sulfuric acid has a strong water absorption, can be used as a dehydrating agent, carbonized wood, paper, cotton and linen fabrics and biological flesh and other carbohydrate-containing substances. When mixed with water, it will also release a lot of heat energy. It is strongly corrosive and oxidizing, so it should be used with caution. It is an important industrial raw material, which can be used in the manufacture of fertilizers, drugs, explosives, pigments, detergents, batteries, etc., and is also widely used in the purification of oil, metal smelting and dyes industries. Commonly used as a chemical reagent, in organic synthesis can be used as a dehydrating agent and sulfonating agent
Packaging, transportation and safety
Store in a cool, ventilated warehouse. The temperature of the warehouse shall not exceed 35 ℃ and the relative humidity shall not exceed 85%. Keep container sealed. Keep away from fire and heat sources. Smoking is strictly prohibited in the workplace. Keep away from flammable and combustible materials. Prevent vapor leakage into the workplace air. Avoid contact with reducing agents, alkalis and alkali metals. Handle and unload lightly to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire fighting equipment and leakage emergency treatment equipment. Empty containers may leave harmful substances. When diluting or preparing the solution, the acid should be added to the water to avoid boiling and splashing and injury to personnel.
