Toxicity | LD50 orally in Rabbit: 825 mg/kg |
Raw Materials | Benzoic acid Ammonia |
colorless Flake crystal or crystalline powder. Slightly benzoic acid odor. Soluble in water, alcohol, glycerol. 1g of the product is dissolved in 4.7ml of water, 1.2 ml of boiling water, 36ml of ethanol, 8ml of boiling ethanol, 8ml of glycerol. Its aqueous solution is slightly acidic. Ammonia was gradually lost in the open air. Combustion or thermal decomposition products include toxic nitrogen oxides and ammonia. Contact with oxidizing agents can cause ignition and explosion.
benzoic acid was dissolved in ammonia water, heated, filtered, and cooled to crystallize to obtain ammonium benzoate.
used as a reagent for chemical analysis. For example, as a precipitating agent, a quantitative gravimetric analysis of metals was performed. For anti-corrosion, Disinfection, adhesives, metal rust treatment and rubber additives.
irritation of the eyes, skin and respiratory system. Staff should be well protected, if accidentally touch the skin and eyes, should immediately rinse with a large amount of flowing water. Store in a closed container, placed in a cool, ventilated place.
