FAQ

What are the physical and chemical properties of Butyl 2-cyanoacrylate (CAS: 6606-65-1)?

Butyl 2-cyanoacrylate (CAS: 6606-65-1) is a colorless to slightly yellowish liquid with a high viscosity. It has a molecular weight of approximately 144.16 g/mol. The compound is soluble in organic solvents but only slightly soluble in water. It is highly reactive, polymerizing rapidly upon contact with moisture or polar solvents, forming a strong adhesive film.

How is Butyl 2-cyanoacrylate (CAS: 6606-65-1) typically synthesized?

Butyl 2-cyanoacrylate (CAS: 6606-65-1) is typically synthesized by the reaction of butyl acrylate with acryloyl isocyanate. The process involves the condensation of these two compounds under anhydrous conditions to yield the cyanoacrylate ester. This reaction is highly selective and yields a high percentage of the desired product.

What industries use Butyl 2-cyanoacrylate (CAS: 6606-65-1)?

Butyl 2-cyanoacrylate (CAS: 6606-65-1) is widely used in the manufacturing of adhesives, particularly in medical applications, where it forms a strong, clear bond. It is also used in the production of coatings, sealants, and polymers. Its use in the semiconductor industry for bonding and encapsulation is also significant.

What precautions should be taken when handling Butyl 2-cyanoacrylate (CAS: 6606-65-1)?

Butyl 2-cyanoacrylate (CAS: 6606-65-1) should be handled with care in a fume hood due to its high reactivity. PPE such as safety goggles, gloves, and a lab coat is required. Spills should be cleaned up immediately using appropriate absorbents, and the area should be well-ventilated. Always follow the safety data sheet (SDS) for detailed handling instructions and emergency procedures.
