Reaction Steps
100 parts by weight of quartz sand were mixed with 65% aqueous-alcohol solution of paratoluenesulphonic acid amounting to 1.2% by weight of the sand, and with phenol formaldehyde resin taken in an amount of 2% by weight of the sand and produced by condensing 1 mole of phenol and 1.2 moles of formaldehyde in the presence of magnesium oxide at a condensing temperature of 70°-75° C.
