Applications
Benzoic acid is an important organic chemical raw material with a wide range of applications:
- Food Industry: As a safe food preservative, it is widely used in fruit juices, jams, canned foods, pickled products and other foods to inhibit the growth of molds, yeasts and bacteria, extending the shelf life of food; it is also used as a flavoring agent to enhance the aroma of food.
- Pharmaceutical Field: Used as an intermediate for synthesizing drugs such as antipyretics, analgesics and antibiotics, and can also be directly used as an external disinfectant and antipruritic.
- Chemical Industry: Used in the production of benzoate esters, plasticizers, dyes, resins and other products; it is also a common reagent in laboratory organic synthesis reactions.
- Other Fields: Used in cosmetics as a preservative and antibacterial agent; used in the preparation of feed additives to improve the storage stability of feed.
Safety Information
Benzoic acid is a moderately irritating chemical. It is corrosive to the skin and mucous membranes, and may cause discomfort such as redness, itching and burning when in direct contact with the skin. When inhaled in large quantities, its dust or vapor can irritate the respiratory tract, causing cough, sore throat and other symptoms. If ingested accidentally, it will stimulate the gastrointestinal tract, leading to nausea, vomiting, abdominal pain and other adverse reactions. When operating, wear chemical-resistant gloves, goggles and dust masks to avoid direct contact with the skin, eyes and respiratory tract. It is strictly prohibited to mix with strong oxidants (such as potassium permanganate) and strong bases (such as sodium hydroxide) to prevent dangerous reactions. Waste materials and contaminated containers should be disposed of in accordance with hazardous waste management regulations, and must not be discarded randomly to avoid environmental pollution.
