Reaction Conditions

Reaction Steps

Phenol (1 mol) and 50% formaldehyde solution (0.6 mol) were charged into a reaction vessel and the temperature held at 44° C. while 50% sodium hydroxide (0.04 mol) was added. The mixture was then heated to 80° C. and a second charge of 50% formaldehyde solution (1.4 mol) was added slowly over a period of 25 minutes. The mix was then held at 80° C. until the viscosity reached 550 cP (about 6 hours). The product was finally cooled to room temperature and discharged.
