1、Vinyl acetate

Vinyl acetate is primarily used as a monomer in the production of polyvinyl acetate and polyvinyl alcohol. Acute (short-term) inhalation exposure of workers to vinyl acetate has resulted in eye irritation and upper respiratory tract irritation.

2、VINYL ACETATE

The Vinyl Acetate Safe Handling Guide was developed by the Vinyl Acetate Council, a not-for-profit association of North American manufacturers, processors and users of vinyl acetate monomer.

3、Measurement of vinyl acetate monomer in consumer products and modeled

Vinyl acetate monomer (VAM) (CAS 108-05-4) is employed in the creation of an array of polymers and copolymers used in the manufacture of consumer products.

4、Vinyl Acetate: Acute Exposure Guideline Levels

Therefore, a one-time exposure even to high concentrations of vinyl acetate would not be expected to result in tumor development. AEGL values for vinyl acetate are presented in Table 7-1.

SCOEL/SUM/104C (final)

In rats LD50 values were in two studies 3470 mg/kg and 3500 mg/kg, respectively. A dermal LD50 value of 7440 mg/kg was determined from a range finding study with rabbits. Vinyl acetate has proven to cause irritation or corrosion to the skin of rabbits depending on the duration of the skin contact.

Toxicological Profile for Vinyl Acetate, Draft for Public Comment

Regulations and Guidelines Applicable to Vinyl Acetate.

In modern industrial society, the environmental and social impacts of chemical production and usage have garnered increasing attention. Vinyl acetate, an essential organic chemical raw material, has sparked widespread discussion regarding its environmental implications during production and application. This paper delves into the issue of vinyl acetate limit values, aiming to provide references and recommendations for the development of this field.

I. Production and Application of Vinyl Acetate

Vinyl acetate (chemical formula: C₂H₄O₂) is a common organic compound with diverse applications, such as a solvent, plasticizer, and emulsifier. Industrially, it is typically synthesized through the esterification reaction of ethylene and acetic acid in the presence of a catalyst. This process involves chemical reactions and may generate byproducts and waste, posing environmental risks.

II. Environmental Impact of Vinyl Acetate

The production and application of vinyl acetate may lead to the following environmental issues:

1. Volatile Organic Compound (VOC) Emissions: Vinyl acetate production may release VOCs, which can contribute to photochemical smog under certain conditions, harming the environment and human health.

2. Wastewater Treatment Challenges: Wastewater generated during production and application may contain high concentrations of ester compounds, complicating treatment processes and requiring advanced methods.

3. Soil and Groundwater Pollution: Improper disposal of vinyl acetate-containing liquids or gases could contaminate soil and groundwater, disrupting ecosystem balance.

III. Formulation and Implementation of Vinyl Acetate Limit Values

To mitigate the environmental impact of vinyl acetate production and application, governments and regulatory bodies worldwide have established limit value standards. These standards are based on:

1. Environmental Protection Requirements: Aligned with laws such as the Environmental Protection Law of the People's Republic of China, they restrict hazardous emissions to safeguard ecological integrity.

2. Economic Feasibility: Balancing economic benefits and environmental needs, given vinyl acetate’s widespread industrial use.

3. Technological Advancements: Encouraging adoption of advanced production technologies and equipment to enhance efficiency and eco-friendliness.

IV. Effects of Implementing Vinyl Acetate Limit Values

China has issued several standards targeting vinyl acetate, such as:

• GB 27631-2011 (Emission Standard of Pollutants for the Synthetic Resin Industry), which specifies emission limits for vinyl acetate.
• GB 27630-2011 (Emission Standard of Air Pollutants for the Synthetic Resin Industry), imposing stricter controls on atmospheric emissions.

These standards have promoted green transformation in the vinyl acetate industry, improved resource utilization efficiency, and reduced environmental pollution.

As a critical organic chemical raw material, vinyl acetate’s environmental impact during production and application cannot be overlooked. Rational limit values effectively control environmental risks, fostering a win-win scenario for economic development and environmental protection. In the future, advancements in technology and heightened environmental awareness are expected to drive a greener, more efficient, and sustainable vinyl acetate production process.
