Mercaptoethanol material safety data table details
Mercaptoethanol is an important chemical substance in the field of chemistry, and the clarity of its properties, hazards and safe disposal is crucial for many industries. This material safety data table (MSDS) will reveal detailed information about 2-mercaptoethanol in a comprehensive way.
First, physical and chemical properties
2-mercaptoethanol, with unique appearance and properties. It usually appears as a colorless and transparent liquid with a strong pungent odor. The melting point and boiling point of this substance are also key characteristics. The melting point is about -100 ° C, and the boiling point is about 157-158 ° C. The relative density is nearly 1.1143 (20 ° C), soluble in water, and can be miscible with most organic solvents. These characteristics lay the foundation for its application in various chemical reactions and industrial processes.
II. Overview of Hazards
From the perspective of health hazards, 2-mercaptoethanol is extremely threatening to the human body. Its vapor or fog droplets can irritate the eyes, skin and respiratory tract. If accidentally exposed to the skin, it may cause serious irritation or even burns; if it enters the eyes, it will cause irreversible damage to the eyes. Long-term or repeated exposure may cause allergic reactions to the skin, and may have adverse effects on vital organs such as the central nervous system, liver and kidneys. As far as the risk of ignition and explosion is concerned, this substance is a flammable liquid. Its vapor and air can form an explosive mixture. In case of open flame and high heat energy, it can cause combustion and explosion. The vapor is heavier than air and can spread to a considerable distance at a lower place. In case of ignition, it will catch fire and ignite back.
3. First aid measures
Once the skin comes into contact, you should immediately remove the contaminated clothes, rinse with a large amount of flowing water for at least 15 minutes, and then seek medical treatment in time. If you are not careful to enter the eye, you should immediately lift the eyelids and rinse thoroughly with a large amount of flowing water or normal saline for at least 15 minutes. You also need to seek medical attention as soon as possible. If inhaled, should quickly leave the scene to fresh air, keep the airway unobstructed, such as breathing difficulties, should be given oxygen, such as breathing stopped, should immediately perform artificial respiration and seek medical attention. If ingested, do not induce vomiting, should immediately seek medical attention, inform the doctor that the intake of the substance is 2-mercaptoethanol.
4. Fire protection measures
For fires caused by 2-mercaptoethanol, the applicable fire extinguishing agents are carbon dioxide, dry powder, and sand. Because water cannot effectively extinguish such flammable liquid fires, it is not suitable to use water to extinguish them. When extinguishing a fire, firefighters must wear an air-carrying breathing apparatus, full-body fire-fighting clothing, extinguish the fire in the upwind direction, move the container from the fire site to an open place as much as possible, and spray water to keep the fire site container cool until the end of the fire.
5. Emergency treatment for leaks
Once a 2-mercaptoethanol leak occurs, the personnel in the leaking contaminated area should be quickly evacuated to the safe area first, and quarantined, strictly restricting access. Emergency personnel must wear self-priming filter gas masks (full masks) and anti-acid and alkali work clothes. Do not come into direct contact with leaks. When a small amount of leakage occurs, it can be mixed with sand, dry lime or soda ash, or it can be rinsed with a lot of water, and diluted with washing water and placed into the wastewater system. When there is a large amount of leakage, an embankment should be built or a pit should be dug for containment, covered with foam to reduce steam disasters, and transferred to a tanker or a special collector with an explosion-proof pump for recycling or transportation to a waste treatment site for disposal.
6. Operation Disposal and Storage
When operating, it should be strictly sealed to provide adequate local exhaust and comprehensive ventilation. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear self-suction filter gas masks (full masks), rubber acid and alkali-resistant clothing, and rubber acid and alkali-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 leakage into the air of the workplace. Avoid contact with oxidants, acids, and alkalis. When handling, it should be lightly loaded and unloaded to prevent damage to packaging and containers. Equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. Harmful substances may remain in empty containers. For storage, it should be stored in a cool and ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30 ° C. Keep the container sealed. It should be stored separately from oxidants, acids and alkalis, and should not be mixed. Use explosion-proof lighting and ventilation facilities. It is forbidden to use machinery and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
The above is the core content of the 2-mercaptoethanol material safety data table, which should be strictly followed by practitioners in all industries to ensure the safety of personnel and the environment from pollution.
