Related Description of Benzyl Cyanide Safety Technical Specification
Benzyl cyanide, also known as phenylacetonitrile, has its specific uses in the chemical industry. According to the main points of its safety technical specification, I will describe it in detail for you.
Benzyl cyanide, at room temperature and pressure, is in the state of a colorless oily liquid. Looking at its appearance, it is clear and has a unique odor. Its physical and chemical properties are quite critical. Its melting point is about -23 ° C, boiling point is 233.5 ° C, and relative density (water = 1) is about 1.02. In terms of solubility, it is slightly soluble in cold water, but miscible with organic solvents such as ethanol and ether.
From the perspective of hazard characteristics, this substance is quite toxic. Inhalation, ingestion or absorption through the skin can cause harm. Its toxicological mechanism is that after entering the human body, cyano groups can be released, which in turn inhibits cellular respiratory enzymes and seriously interferes with the normal physiological metabolism of the human body. During acute poisoning, the initial symptoms are often headache, dizziness, fatigue, chest tightness, breathing difficulties, etc. The disease progresses, which can cause confusion, convulsions, and even respiratory failure, which is life-threatening. Skin contact can cause irritation, causing redness, swelling, and pain; eye contact can also cause irritation to the conjunctiva and bring discomfort.
In terms of fire protection measures, benzyl cyanide is flammable. In case of open flames and hot topics, there is a risk of combustion and explosion. When extinguishing a fire, it is appropriate to use anti-soluble foam, dry powder, carbon dioxide and other fire extinguishing agents. Rescue personnel must wear gas masks and full-body fire suits to extinguish fires upwind.
Talking about emergency treatment of leaks, in the event of a leak, personnel should be quickly evacuated from the leaked contaminated area to a safe area and quarantined to strictly restrict access. Emergency personnel need to wear self-contained positive pressure breathing apparatus and protective clothing. In the event of a small leak, it can be adsorbed or absorbed by sand or other non-combustible materials; if there is a large leak, it is necessary to build an embankment or dig a pit for containment, cover it with foam to reduce steam disasters, and then transfer it to a tanker or a special collector for recycling or transportation to a waste treatment site for disposal.
There are also strict requirements for operation, disposal and storage. The operation should be carried out in a well-ventilated place. The operator must undergo special training and strictly abide by the operating procedures. It is recommended that the operator wear a self-priming filter gas mask (full mask), a tape gas suit, and rubber oil-resistant gloves. Keep away from fire and heat sources. Smoking is strictly prohibited in the workplace. When storing, it should be placed in a cool and ventilated warehouse, away from fire and heat sources. The storage temperature should not exceed 30 ° C. It should be stored separately from oxidizing agents, reducing agents, acids, and alkalis, and should not be mixed. Equipped with corresponding varieties and quantities of fire-fighting equipment. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
Understanding the content of the safety technical specification for benzyl cyanide is of great significance to those who are engaged in related work in ensuring their own safety, preventing accidents, and effectively responding to emergencies.
