What are the hazards of high concentration sulfuric acid

High-concentration sulfuric acid is called bad water by many people in life, because high-concentration sulfuric acid is not only highly corrosive, but also a strong mineral acid. It also has good dehydration properties, strong corrosiveness, low volatility, strong acidity, etc. If the human body comes into contact with it, it will be seriously injured, and in severe cases it will cause death. So what are the hazards of high concentration sulfuric acid?

First, what are the hazards of high concentration sulfuric acid? Sulfuric acid is extremely corrosive, especially high concentration sulfuric acid. High concentrations of sulfuric acid are not only strongly acidic, but also have strong dehydrating and oxidizing properties: in addition to hydrolyzing the proteins and fats in the body and causing severe chemical burns, it also undergoes a highly exothermic dehydration reaction with carbohydrates and carbonizes them, causing secondary flame burns and causing great damage to the eyes and skin.

Second, health hazards: It has strong irritating and corrosive effects on skin, mucous membranes and other tissues. Vapor or mist can cause conjunctivitis, conjunctival edema, corneal opacity, and even blindness; cause respiratory tract irritation, and in severe cases, dyspnea and pulmonary edema; high concentrations can cause laryngeal spasm or glottal edema, leading to suffocation and death. After oral administration, it causes digestive tract burns and even ulcer formation; in severe cases, it may cause gastric perforation, peritonitis, kidney damage, shock, etc. Skin burns can cause erythema in mild cases and ulcers in severe cases. After healing, the scars shrink and affect function. Splashing into the eyes can cause burns, or even corneal perforation, panophthalmitis and even blindness. Chronic effects: dental erosion, chronic bronchitis, emphysema and pulmonary cirrhosis.

Third, physical and chemical properties and uses: Colorless oily corrosive liquid with strong hygroscopicity. Density: 1.8g/cm³, melting point 10.4℃, boiling point: 338℃. Used in the manufacture of ammonium sulfate, phosphoric acid, aluminum sulfate synthetic drugs, synthetic dyes, synthetic detergents and metal pickling agents.

What are the hazards of high concentration sulfuric acid? Environmental hazards: It is harmful to the environment and can cause pollution to water and soil. Explosion hazard: This product is combustion-supporting, highly corrosive and irritating, and can cause burns and carbonization of skin and flesh. The raw materials for industrial production of sulfuric acid include sulfur, pyrite, non-ferrous metal smelting flue gas, gypsum, hydrogen sulfide, sulfur dioxide and waste sulfuric acid. Sulfur, pyrite and smelting flue gas are the three main raw materials.
