Second, the main use
Synthetic polyvinyl alcohol (PVA): PVA is a water-soluble polymer material with excellent performance, widely used in textiles, paper, adhesives, coatings and other fields.
Manufacture of polyvinyl acetate (PVAc) emulsion: PVAc is an important adhesive, commonly used in woodworking glue, paper products bonding and architectural coatings.
Copolymer production: vinyl acetate can be copolymerised with other monomers such as ethylene and propylene to produce a variety of copolymers with excellent properties. For example, ethylene vinyl acetate copolymer (EVA) because of its excellent flexibility, transparency and chemical resistance, is widely used in shoe materials, film and wire and cable industries.
Other chemical products: vinyl acetate is also used in the production of coatings, fibres and paper coating agents.
Preparation method
Ethylene oxidation method: this is the main method of producing vinyl acetate in the industry at present. This method takes ethylene, acetic acid and oxygen as raw materials, and generates vinyl acetate through gas-phase oxidation reaction under the action of palladium (Pd)-copper (Cu)-based catalyst. This method has the advantages of mild reaction conditions, high yield and easy availability of raw materials.
Acetylene method: This is the method used earlier in history to produce vinyl acetate. This method uses acetylene and acetic acid as raw materials and reacts in the presence of a zinc salt catalyst to produce vinyl acetate. However, due to the high production cost of acetylene and high operational risk, acetylene method is gradually replaced by ethylene oxidation method.
Industry chain and market situation
Upstream raw materials: the upstream raw materials of vinyl acetate mainly include acetylene, acetic acid, ethylene and hydrogen.
Downstream application: The downstream application of vinyl acetate is extensive, mainly including the production of polyvinyl alcohol (PVA), polyvinyl acetate (PVAc), EVA and other polymers, which have a wide range of applications in the fields of construction, textile, light industry, papermaking, automobile and so on.
Market supply and demand: China is the world's top producer of vinyl acetate, with production capacity accounting for about 40% of the world's total. In recent years, China's vinyl acetate market has been expanding steadily with the growth in demand for downstream EVA and other products. However, at present, China's overall vinyl acetate overcapacity, high-end products still need to be imported.
