F. Production method: phenol, diisobutene alkylation method. G. Physical and chemical properties: appearance and properties: white flakes, flammable, slightly phenol odor; Relative density (water = 1): 0.941, boiling point (°C): 280~283, flash point (°C): 138; Solubility: slightly soluble in water, miscible with ethanol, acetone, etc. H. Storage and transportation conditions:
Store in a cool, dry, dark warehouse, away from the heat source of tinder. The temperature of the warehouse should not exceed 40 °C. Keep the package sealed. It should be stored separately from oxidants, strong alkalis, edible chemicals, etc., and mixed storage should be avoided. Explosion-proof lighting is adopted.
I. Toxicity and protection:
Corrosive to the skin, eyes and mucous membranes, it can cause congestion, pain, burning sensation, blurred vision. Inhalation of a large amount of its vapor can cause cough, shortness of breath, difficulty breathing, and severe cases can cause pulmonary edema. Mistaken can cause poisoning. Frequent contact with the skin can depigment the skin. In case of heat, highly toxic phenolic smoke is released. Environmental hazards: The substance is harmful to the environment, and special attention should be paid to the pollution of water bodies. Explosion hazard: combustion caused by open flame and high heat energy. Closed operation, enhanced ventilation. Operators must be specially trained and strictly follow operating procedures. It is recommended that operators wear gas masks, chemical protective glasses, anti-penetration overalls, and rubber oil-resistant gloves. Keep away from fire and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent its vapor from leaking into the workplace air. Production and packaging sites should be equipped with corresponding varieties and quantities of fireproof equipment, as well as leakage emergency treatment equipment.
