Reaction Steps
In terms of weight, 110 parts of resorcinol, 0.62 part of oxalic acid, and 248 parts of water were charged into a flask, to which 50 parts of 37% formalin was dropwise added at 60° C. in one hour under stirring. Then, the stirring was further continued for 1 hour to obtain a resorcinol-formaldehyde condensate (B) containing excess resorcinol.
