Bakelite (Phenol Formaldehyde Resin)
Bakelite is made from phenol and formaldehyde in the presence of a base catalyst. It involves formation of methylene bridges at the ortho and para positions. The reaction starts with the initial formation of ortho and/or para-hydroxymethyl phenol derivatives which further react with phenol to form ..
