Introduction
Vinyl glycol ether, also known as 2-vinyl-1,2-ethylene glycol ether, is an organic compound.The properties of vinyl glycol ether are mainly manifested in physical properties and chemical properties. It is a colorless to pale yellow liquid with a peculiar odor. It is soluble in organic solvents such as water, alcohol, and ether. Vinyl glycol ether also has certain surface activity and solubilizing properties.Vinyl glycol ether has a wide range of applications in industry. It is often used as a thinner in coatings, inks, adhesives, dyes, and lubricants. It has good solubility and solubilization, which can make the system more stable and improve the performance of the product.The methods for preparing vinyl glycol ether generally include etherification reaction and dehydration reaction. Among them, the etherification reaction is often prepared by esterification reaction of ethylene glycol and ethylene compounds, and the dehydration reaction is to dehydrate ethylene glycol through dehydrating agents (such as sulfuric acid, etc.) to produce vinyl ethylene glycol ether.Safety information of vinyl glycol ether: It is a chemical that is irritating to the human body, and direct contact with the skin and eyes should be avoided. When using or operating, wear appropriate protective equipment, such as gloves, goggles, etc. During storage and transportation, direct sunlight and contact with flammables, oxidants and other substances should be avoided to prevent fire or explosion accidents. If inadvertently inhaled or accidentally ingested, seek medical treatment promptly.
Application
2-(Vinyloxy)ethanol (Ethylene glycol monovinyl ether, CAS 764-48-7) is a high-purity, bifunctional monomer containing both a reactive vinyl ether group and a primary hydroxyl group. This unique structure enables both polymerization and post-functionalization, making it a versatile building block in specialty polymer synthesis. As a reactive diluent in UV-curable and peroxide-cured systems, it reduces formulation viscosity for high-solid coatings, adhesives, printing inks, and sealants, improving flexibility, adhesion, and chemical resistance. Its hydroxyl group allows copolymerization with isocyanates, anhydrides, and carboxylic acids, enabling the synthesis of poly(vinyl ether) copolymers with tailored hydrophilic/hydrophobic properties. A major application is as the key intermediate for polycarboxylate superplasticizers (PCEs) in high-performance concrete, where it provides superior water-reducing efficiency, low sensitivity to clay and stone powder, and excellent slump retention compared to conventional allyl alcohol-based PCEs. It is also used to produce elastomers, lubricants, hairsprays, foams, and surface protection materials.
