Triethyl orthoformate safety data table related content
Triethyl orthoformate, as an organic compound, its safety data table (Triethyl Orthoformate Sds) has a detailed description of many aspects.

In terms of its physical and chemical properties, triethyl orthoformate is usually a colorless and transparent liquid with a special odor. The boiling point is about 143 ° C, and the relative density (water = 1) is about 0.89. It is slightly soluble in water and miscible in most organic solvents such as ethanol and ether.

From the perspective of hazard overview, triethyl orthoformate is flammable, and its vapor and air can form an explosive mixture, which can cause combustion and explosion in case of open flame and high heat. It can react strongly with oxidants. Its vapor is heavier than air and can spread to a considerable distance at a lower place. In case of fire, it will catch fire and backfire. It has a irritating effect on the eyes and respiratory tract mucosa. If it is accidentally touched, it may cause discomfort.

In terms of first aid measures, after skin contact, you should immediately take off the contaminated clothes, rinse with a lot of flowing water for at least 15 minutes, and then seek medical attention; when in contact with the eyes, lift the eyelids, rinse with flowing water or normal saline, and seek medical attention; if inhaled, quickly leave the scene to a fresh air place to keep the respiratory tract unobstructed, such as breathing difficulties, give oxygen, if breathing stops, immediately perform artificial respiration and seek medical attention; if eaten by mistake, drink enough warm water, urge vomiting, seek medical attention.

In terms of fire protection measures, due to its flammability, anti-soluble foam, carbon dioxide, dry powder, sand and other fire extinguishing agents can be used when extinguishing the fire. Fire extinguishers need to wear gas masks, wear full-body fire suits, and extinguish the fire in the upwind direction. Spray water to cool the container, and move the container from the fire site to an open area if possible. If the container in the fire site has changed color or produces sound from the safety pressure relief device, it must be evacuated immediately.

In the emergency treatment of leaks, quickly evacuate the personnel in the contaminated area of the leak to the safe area, and isolate and strictly restrict access. Cut off the source of fire. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and anti-static work clothes. Cut off the source of leakage as much as possible. Prevent it from flowing into the restricted space such as sewers Small leaks: Absorb with sand, vermiculite or other inert materials. It can also be scrubbed with emulsion made of non-combustible dispersants, and the lotion is diluted and placed into the wastewater system. Large leaks: Build embankments or dig pits for containment. Cover with foam to reduce vapor disasters. Transfer to a tanker or special collector with an explosion-proof pump for recycling or transportation to a waste treatment site for disposal.

In terms of operation, disposal and storage, the operation should be carried out in a well-ventilated place. The operator must be specially trained and strictly abide by the operating procedures. It is recommended that the operator wear a self-priming filter gas mask (half mask), chemical safety protective glasses, anti-static overalls, and rubber oil-resistant gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent steam from leaking into the air in the workplace. Avoid contact with oxidants and acids. Filling should control the flow rate and prevent static electricity from accumulating. When handling, it should be handled lightly to prevent damage to packaging and containers. Equip with the corresponding variety and quantity of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may remain harmful substances. Store in a cool and ventilated warehouse. Keep away from fires and heat sources. The warehouse temperature should not exceed 30 ° C. Keep the container sealed. It should be stored separately from oxidants and acids, and should not be mixed. Use explosion-proof lighting and ventilation facilities. Prohibit the use of machinery and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
