1,4-Butanediyl bisacrylate(CAS: 1070-70-8)

The physical and chemical properties of 1,4-Butanediyl bisacrylate include a molecular weight of approximately 160.22 g/mol. It is a colorless, crystalline solid with a low melting point of around 52°C. This compound is moderately soluble in common organic solvents such as acetone and toluene but is insoluble in water. It exhibits excellent reactivity due to its acrylate groups, making it suitable for polymerization processes.

1,4-Butanediyl bisacrylate is commonly synthesized via the acrylation of 1,4-butanediol. The process typically involves the reaction of 1,4-butanediol with acryloyl chloride under anhydrous conditions in the presence of a base like triethylamine. The reaction is conducted at room temperature or slightly elevated temperatures to ensure selectivity and yield of the bisacrylate product.

1,4-Butanediyl bisacrylate is widely used in the polymer industry, particularly in the production of acrylic resins and coatings. It is also utilized in the manufacturing of adhesives, sealants, and pressure-sensitive tapes. This compound is also found in specialized applications such as sensors and semiconductor materials, where its reactivity and stability are advantageous.

When handling 1,4-Butanediyl bisacrylate, it is essential to wear appropriate personal protective equipment (PPE) including gloves, safety goggles, and chemical-resistant clothing. Work should be conducted in a well-ventilated area or a fume hood to prevent inhalation of vapors. Spills should be cleaned up using appropriate absorbent materials, and the area should be flushed with water. Always consult the safety data sheet (SDS) for detailed handling and disposal information.
