Methyl cyanoacrylate (MCA; also sometimes referred to as α-cyanoacrylate or alpha-cyanoacrylate) [3] is an organic compound that contains several functional groups: a methyl ester, a nitrile, and an alkene. It is a colorless liquid with low viscosity. Its chief use is as the main component of cyanoacrylate glues.
The acrylate ion is the anion CH 2 =CHCO − 2. Often, acrylate refers to esters of acrylic acid, the most common member being methyl acrylate. These acrylates contain vinyl groups. These compounds are of interest because they are bifunctional: the vinyl group is susceptible to polymerization and the carboxylate group carries myriad ...
CH 2 =C(CH 3)CN + H 2 SO 4 + H 2 O → CH 2 =C(CH 3)−CONH 2 ·H 2 SO 4 CH 2 =C(CH 3)−CONH 2 ·H 2 SO 4 + CH 3 OH → CH 2 =C(CH 3)COOCH 3 + NH 4 HSO 4. Mitsubishi Gas Chemicals proposed that MAN can be hydrated to methacrylamide without using sulfuric acid and is then esterified to obtain MMA by methylformate. [10] CH 2 =C(CH 3)CN + H 2 O ...

An acrylic resin is a thermoplastic or thermosetting plastic substance typically derived from acrylic acid, methacrylic acid and acrylate monomers such as butyl acrylate and methacrylate monomers such as methyl methacrylate. Thermoplastic acrylics designate a group of acrylic resins typically containing both a high molecular weight and a high ...
The compound 2-octyl cyanoacrylate degrades much more slowly due to its longer organic backbone (series of covalently bonded carbon molecules) and the adhesive does not reach the threshold of tissue toxicity. Due to the toxicity issues of ethyl cyanoacrylate, the use of 2-octyl cyanoacrylate for sutures is preferred. [33]
Methyl acrylate can be prepared by debromination of methyl 2,3-dibromopropanoate with zinc. [10] Methyl acrylate is formed in good yield on pyrolysis of methyl lactate in the presence of ethenone (ketene). [11] Methyl lactate is a renewable "green chemical". Another patent [12] describes the dehydration of methyl lactate over zeolites.
