Styrene vinyl acetate, also known as styryl acetate, has a chemical formula of C11H12O2 and a molecular weight of 176.21. It is a colorless liquid with ester properties, soluble in organic solvents, but insoluble in water. Because of its good physical and chemical properties and a wide range of applications, styrene vinyl acetate has become an important raw material in many industrial production and scientific research.

However, there are also safety and quality problems in the storage and use of styrene vinyl acetate, which require our attention. The following are some precautions for storing and using this chemical:

1. Storage environment: The storage environment of styrene vinyl acetate should be dry and well ventilated, away from fire, heat sources and oxidants. The storage room temperature should be controlled below 25 ℃ to prevent high temperature from causing chemical decomposition or deterioration. Storage containers should be colorless, odorless, corrosion-resistant materials, such as stainless steel or glass containers, and try to avoid high-altitude storage or long-term storage.

2. packaging: styrene vinyl acetate should try to use the original sealed packaging, so as not to be contaminated by the outside world during storage and use. After opening the container, use or transfer should be carried out immediately to avoid degradation of the chemical due to unnecessary exposure time.

3. Protective measures: the staff should wear masks, gloves, protective glasses and other personal protective equipment when exposed to styrene vinyl acetate. If you have irritating respiratory tract reactions, coughing, dizziness and other uncomfortable symptoms, you should immediately stop contact, wash the skin, eyes and other parts, and fully ventilate. During the use of styrene vinyl acetate, it is also necessary to avoid contact with fire sources and high heat substances to avoid fire and explosion.

4. Application: Styrene vinyl acetate is widely used in synthetic resins, fibers, etc., but there is also a certain risk. Before use, you should first understand the chemical model, quality and other information, in order to correctly determine its scope of application and use. At the same time, the regulations on the use of hazardous chemicals should be strictly enforced, and the national and local regulations on the management of chemicals should be observed.

styrene vinyl acetate is a very important chemical, it also has certain risks and quality requirements during storage and use. We must learn to manage and use the chemical correctly in order to ensure its safe and effective application.
