Bakelite The mechanism - Florida State College at Jacksonville

Bakelite Bakelite is one of the earliest commercial plastics. When made with this procedure, it is often an amber clear solid. To make it stronger and to make more of it, filler such as sawdust is often added. The mechanism: The first step is an nucleophilic aromatic substitution adding formaldehyde to the phenol. This can occur at the ortho and para positions. O H H O OH OO OH OH O OH OH OH ...
