Methyl Cyanoacrylate Superglue By: Nicole LeBlanc

Is the molecule naturally occurring? Is it synthesized? Where does it come from? It is not naturally occurring. It is not naturally occurring. It can be synthesized or made form organic resins. It can be synthesized or made form organic resins. CA’s (cyanoacrylate adhesives) are produced in heated kettles. Initial ingredient is ethyl cyanocetate, placed into a glass-lined kettle with revolving mixing blades, this material is then mixed with formaldehyde. The mixing triggers condensation, a chemical reaction that produces water. The water is then evaporated as the kettle is heated. CA’s (cyanoacrylate adhesives) are produced in heated kettles.

What are the direct and indirect uses of this product? This product is used to form a surface attachment between discrete materials. This product is used to form a surface attachment between discrete materials. Superglue forms the strongest bonds and clean breaks of non-porous materials, such as plastic, rubber, and metal. Once exposed to the air, it bonds instantly and sets in seconds. Cyanocrylates are mainly used as adhesives.

When was it discovered? How was it discovered? This product was first discovered in 1949 and invented in 1951 by Dr. Harry Coover. This product was first discovered in 1949 and invented in 1951 by Dr. Harry Coover. Coover was working for Kodak laboratories, he was working with cyanoacrylates that seemed to be stuck to everything they touched! Coover failed to see their potential as adhesive until one of his research students made ethyl cyanoacrylate, the main constituent of superglue. On measuring the refractive index to determine the purity of his sample, he found that he couldn’t separate the two prisms. Something no one has ever seen before.
