Sulfuric acid (chemical formula:?? H SO) of analytically pure m-xylene, the most important sulfur oxyacids. Sulfuric anhydride as a colorless oily liquid, 10.36 ℃ crystallization, typically using an aqueous solution of its various different concentrations, whichever is in contact with the tower method and Method. The former income as a crude sulfuric acid isopropyl toluene AR, mass fraction is generally about 75%; the latter can be obtained 98.3% of the mass fraction of pure concentrated sulfuric acid, boiling point 338 ℃, relative density of 1.84. Sulfuric acid is one of the most active binary inorganic acid, the reaction can take place, and many metals. High concentrations of sulfuric acid has a strong water absorption, can be used as a dehydrating agent, carbonized wood, paper, cotton fabric and flesh, such as carbohydrate-containing biological substances. When mixed with water, will release a lot of heat. It has a strong resistance and oxidation resistance, so use it with caution. Is an important industrial raw material toluene AR can be used to manufacture fertilizers, drugs, explosives, paints, detergents, batteries, etc., are also widely used in the purification of petroleum, metal smelting and other industrial dyes. Used as chemical reagents of analytical grade toluene shelf life, can be used as a dehydrating agent and a sulfonating agent in organic synthesis. Handling Precautions: closed operation, pay attention to ventilation. Operating as mechanization and automation. The operator must go through specialized training, strict adherence to rules. Proposed operators wear self-absorption filter respirators (full cover), wear rubber acid suit, wearing rubber gloves acid. Away from fire, heat, workplace smoking. Prevent vapor leakage into the workplace air. Avoid contact with reducing agents, alkalis, alcohols, alkali metal. When moving to light light unloading, packaging and containers to prevent damage. Corresponding with the variety and quantity of fire equipment and spill response equipment. Empty containers may be harmful residues. Upon dilution or in preparing solutions, the acid should be added to the water to avoid boiling and splashing.
