Abstract

PURPOSE: To prepare a water-soluble resol resin having excellent shelf stability and affinity for fibers, by the mild and uniform reaction of phenol with formaldehyde prepared by air oxidation of methanol.
CONSTITUTION: A gaseous or liquid mixture containing 50W62% of formaldehyde is prepared by air oxidation of methanol. The mixture is absorbed and dissolved in a phenol compound, e.g. cresol. etc., to give the composition wherein formaldehyde/phenol=1W3 (molar ratio), water/phenol=0.5W1 (weight ratio), and methanol/ formaldehyde ≤ 0.2(weight ratio). Sodium hydroxide, etc. is added to adjust pH to 9W10 and the reaction is carried out preferably at ≤ 65°C to give a water- soluble resol resin. The resin is neutralized with acetic acid, etc. to provide the desired resin.
EFFECT: The storage stablility under nitrogen atmosphere is improved. The resin is useful as binders for thermal insulating materials, wood adhesives, etc..
