CAS NO .: 97-63-2

 Properties: Ethyl methacrylate (EMA) is a colorless liquid and easy to volatilize with a spicy smell.

 Melting point (°C): -75

 Boiling point (°C): 117~119

Uses of EMA

EMA monomer is a commonly used polymerizable monomer and can be used as an intermediate for adhesives, coatings, fiber treatment agents, molding materials, and also for the manufacture of acrylic copolymers. It can be copolymerized with methyl methacrylate to improve its brittleness. It can also be used to make organic glass, synthetic resin, and molding powder.

 EMA is used for preparing polymers, copolymers, synthetic resins, organic glass and coatings.

Storage of EMA

EMA liquid is a colorless liquid and easy to volatilize with a spicy smell. It is slightly soluble in water and miscible in alcohol and ether. It should be stored in cool and ventilated warehouses, and be kept away from fire, heat sources, and light. The temperature in warehouses should not exceed 37°C. It should be sealed in packaging and must not come into contact with air.

At room temperature, EMA is a colorless liquid and easy to volatilize with a spicy smell. It is slightly soluble in water and miscible in alcohol and ether. It is stored and easily deteriorated due to polymerization, and it is necessary to add a polymerization inhibitor. It is highly flammable and its vapor can form an explosive mixture with air. It is a toxic chemical harmful to human body when inhaled, orally taken or absorbed through the skin. Its vapor or smoke is irritating to the eyes, skin, mucous membranes, and upper respiratory tract. Its poisoning symptoms include a burning sensation, cough, wheezing, shortness of breath, laryngitis, headache, nausea, vomiting, and allergic reactions. It can be used as an intermediate for adhesives, coatings, fiber treatment agents, and molding materials.

R11: EMA is highly flammable.

R36/37/38: EMA is irritating to eyes, respiratory system and skin.

R43: EMA may cause sensitization by skin contact.

S16: EMA should be kept away from sources of ignition.

S29: Do not empty EMA into drains.

S33: Take precautionary measures against static discharges. Take measures to prevent static electricity from occurring.

S9: Keep the storage container in a well-ventilated place.

Explosive hazardous characteristics

When mixed with air, EMA can explode.

Flammability hazard characteristics

In case of fire, high temperature, or oxidant, EMA is likely to fame; Its burning produces irritating smoke.

Storage and transportation characteristics of EMA

The warehouse should be ventilated and kept dry at low temperatures; It should be stored separately from oxidants and acids; It should not be stored for a long time in case of polymerization.

Extinguishing agents

Dry powder, dry sand, carbon dioxide, foam, and 1211 fire extinguishing agent.

Application of VAM

used in the production of polyvinyl alcohol, coatings and adhesives.It is an important organic chemical material.Vinyl acetate by its polymerization or copolymerization with other monomers,mainly use for the production of polyvinyl acetate (PVAc),polyvinyl alcohol (PVA),vinyl acetate - ethylene copolymer emulsion (VAE) or vinyl acetate copolymer (EVA) resin,vinyl chloride copolymer (EVC), acetal resins such as derivatives. These derivatives usage is very extensive and can be used for bonding agent, and glue pharmaceutical of paper or fabric, coating, ink, leather processing, fibre processing, emulsifier, water soluble film, soil conditioner,.VAM is an important synthetic material monomer. with the progress of science and technology, other downstream products and new applications are still in constant development.

Vinyl acetate is used to make other  industrial chemicals.These chemicals are used mainly to make glues for the packaging and building industries.They are also used to make paints,textiles,and paper.Vinyl acetate is also used as a coating in plastic films for food packaging and as a modifier of food starch.

Physical properties of VAM

Melting point: -93 °C

Boiling point: 72-73 °C (lit.)

Density: 0.934 g/mL at 25 °C (lit.)

Chemical properties: It's a colorless flammable liquid with a sweet ether smell. It's miscible with ethanol, soluble in ether, acetone, chloroform, carbon tetrachloride and other organic solvents, and insoluble in water.

Uses of VAM

Vinyl acetate is the main raw material for the production of synthetic fiber vinylon. Self-polymerization of vinyl acetate or copolymerization with its monomers creates polyvinyl alcohol (PVA), vinyl acetate copolymer (EVA), vinyl chloride copolymer (EVC), vinyl acetate-acrylonitrile fiber, and vinyl acetate-acrylate copolymers, which have important industrial applications and are widely used as adhesives, architectural coatings, textile sizing agents and finishing agents, paper reinforcements and used for the manufacture of safety glass. Ethyl acetate reacted with ethanol and bromine produces bromoacetaldehyde diethyl acetal, which is the intermediate of the drug methimazole.

Invasive route of VAM

inhalation, ingestion, and percutaneous absorption.

Health hazards of VAM

This product is irritating to eyes, skin, mucous membranes and upper respiratory tract. Prolonged exposure creates an anesthetic effect, thus rapid withdraw from its leaking and contaminated areas to safe areas and isolation and strict access restriction are necessary. In addition, fire should be separated. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and protective fire protection clothing. Cut off sources of leakage as much as possible to prevent it floating into sewers, flood drains and other restricted spaces.

For a small amount of its leakage, vinyl acetate monomer can be absorbed with sand or other non-combustible materials. It can also be scrubbed with a non-combustible dispersant, which will be later diluted and poured into the waste water system.

For a large amount of its leakage, it can be dealt with by constructing embankments or digging pits for containment. The spray-like water is used to cool and dilute its vapor, protecting the on-site personnel and diluting the vapor into incombustibles. Use explosion-proof pump to transfer it to the tanker or special collector and have it recycled or transported to waste disposal sites for treatment.
