Malonic acid is an organic acid with the chemical formula HOOCCH2COOH, which is soluble in water, alcohol, ether, acetone and pyridine, and exists in beetroot in the form of calcium salt. Therefore, malonic acid is also called carotid acid, beet acid, malic acid, and methane di-short acid.
Malonic acid is a strong acid that can irritate the eyes, skin, mucous membranes and upper respiratory tract, and can be harmful in high concentrations. Contact can cause a burning sensation, cough, laryngitis, headache, nausea and vomiting. And it is harmful to the environment and can cause pollution to water bodies and the atmosphere. Therefore, the following precautions should be observed during use, preparation, storage, and transportation.
First Aid Precautions
When the skin comes into contact with malonic acid, the contaminated clothing should be removed and rinsed with running water. If burns occur, treat them as acid burns.
In case of eye contact, immediately open the upper and lower eyelids and rinse with running water for 15 minutes. Seek medical attention. When inhaled, quickly leave the scene to fresh air. Give oxygen if breathing is difficult. Once breathing stops, begin CPR immediately. Seek medical attention.
When ingested by mistake, drink milk or egg white to the person who swallowed by mistake. Seek medical attention.
Fire Precautions
Malonic acid is decomposed by high heat and emits irritating fumes. Powder and air can form an explosive mixture, and when it reaches a certain concentration, it will explode when it encounters Mars. Therefore, firefighters must wear gas masks and full-body firefighting suits, and use mist water, foam, carbon dioxide, dry powder, sand and other fire extinguishing agents to extinguish the fire in the upwind direction.
Precautions in the event of a spill
Cut off the fire source. Emergency personnel should wear gas masks and general fire protective clothing. Rinse with plenty of water, and put the diluted lotion into the wastewater system. In case of a large amount of leakage, collect and recycle or discard after harmless treatment.
Operation precautions
The airtight operation, and full ventilation. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety goggles, anti-poison infiltration overalls, and rubber gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Avoid generating dust. Avoid contact with oxidizing agents, reducing agents, and alkalis when handling, loading and unloading lightly to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may be harmful residues.
Storage Precautions
Store in a cool, ventilated warehouse. Keep away from fire and heat sources. It should be stored separately from oxidizing agents, reducing agents, and alkalis, and should not be stored together. Equipped with the appropriate variety and quantity of fire equipment. Storage areas should be equipped with suitable materials to contain spills.
Shipping Precautions
The packaging should be complete and the loading should be secure at the time of shipment. During transportation, it is necessary to ensure that the container does not leak, collapse, fall or be damaged. It is strictly forbidden to mix and transport with oxidizing agents, reducing agents, alkalis, food chemicals, etc. During transportation, it should be protected from sun exposure, rain and high temperature. Vehicles should be thoroughly cleaned after transportation.
Summarize
Malonic acid as one of the common chemicals. It plays an important role in the manufacture of spices, adhesives, fungicides, surface treatment agents for leather and aluminum products, electroplating polishing agents, foam plastic foaming agents, nuclear reactor cleaning agents, heat welding fluxes, and explosive control agents. But malonic acid contains certain hazards. Therefore, safety and protection should be done when everyone uses, prepares, stores, and transports.
