Reaction Steps

Into a reactor equipped with a thermometer, an agitator, a reflux apparatus and a dropping funnel were charged 124 parts (1 mol) of m-methoxyphenol, 0.62 part of oxalic acid and 248 parts of acetone, and 23.4 parts of 37% aqueous formaldehyde solution was added dropwise to the mixture in 1 hour while agitating the resulting mixture at 60° C. Immediately after completion of the addition, 62 parts (0.5 mol) of resorcin and 0.31 part of oxalic acid were added to the mixture, and then 39.2 parts of 37% aqueous formaldehyde solution was added to the mixture in 2 hours while agitating the resulting mixture at 60° C., and further an agitation was continued for 3 hours at 60° C. Then, acetone and water were removed from the reaction solution, the residue was charged into a distillator, and unreacted m-methoxyphenol and resorcin were removed by a distillation under reduced pressure to obtain a m-methoxyphenol/resorcin/formaldehyde cocondensate.
