Introduction
Quality:4-Hydroxybutyl vinyl ether is a clear, colorless liquid with low volatility. It is miscible with many organic solvents but is almost insoluble in water. It has certain oxidation resistance and chemical stability.Use:4-Hydroxybutyl vinyl ether is commonly used in industry as a monomer for polymerization reactions, which can be polymerized into polymers with different degrees of polymerization. It can also be used as an intermediate in adhesives, coatings, resins, dyes, and functional materials.Method:4-Hydroxybutyl vinyl ether can be obtained by the reaction of 2-butenol with etherifying agents such as sulfates, etherified phenols or chloroethers. In the reaction, the etherifying agent is first mixed with an alkali catalyst and then reacted with 2-butenol, which is carried out at the appropriate temperature and time. At the end of the reaction, the pure product is obtained by distillation and purification.Safety Information:Appropriate safety measures need to be taken when using or handling 4-hydroxybutyl vinyl ether. It can have an irritating effect on the human body, contact with skin and eyes should be avoided, and operation in a well-ventilated area should be ensured. Personal protective equipment such as chemical goggles, gloves and gowns should be worn. During storage and transportation, avoid contact with high temperatures, ignition sources, and oxidants to prevent fire or explosion. In the event of a leak, appropriate clean-up measures should be taken quickly to avoid entering the water body or sewer.
Application
1,4-Butanediol vinyl ether (4-Hydroxybutyl vinyl ether, HBVE) is a versatile bifunctional monomer containing a vinyl group and a terminal hydroxyl group. Its unique structure enables both free-radical and cationic polymerization, making it an excellent building block for specialty polymers. In UV-curable coatings and adhesives, it functions as a low-toxicity reactive diluent for radiation-cured systems, reducing formulation viscosity without volatile organic compounds while improving adhesion, flexibility, and chemical resistance. HBVE is also a key comonomer for fluorinated resins used in aerospace and microelectronics, and enhances polymer weatherability and oil resistance. As a hydroxyl-functional crosslinker, it enables room-temperature curing with polyisocyanates and melamine resins. Ethoxylated HBVE serves as a monomer for high-range water-reducing concrete admixtures. In organic synthesis, it acts as a versatile intermediate for pharmaceutical and agrochemical research.
