2-Cyanoacrylic acid methyl ester , also called methyl cyanoacrylate , is a nitrile derivative of the methyl ester of acrylic acid . It belongs to the group of acrylates , more precisely cyanoacrylates .
2-Cyanoacrylic acid methyl ester is a colorless liquid with a characteristic odor, which polymerizes very quickly on contact with moisture . It is the simplest 2-cyanoacrylic acid ester, which also includes 2-cyanoacrylic acid ethyl ester , 2-cyanoacrylic acid butyl ester and others.
2-Cyanoacrylic acid methyl ester can be produced by reacting cyanoacetic acid methyl ester with formaldehyde in a condensation reaction
2-Cyanacrylsäuremethylester is mainly used as superglue used and cured most often in less than a minute. In addition to household use, it is also used in medicine for sutures without thread. It is in vapor form in the forensics used fingerprints to make them visible. The compound was first investigated by researchers from Eastman Kodak in the 1930s / 1940s and patented in 1956.
