    摘要: Sodium paraformylphenolate crystallized with two molecules of water is manufactured by:(a) condensing glyoxylic acid with an excess of phenol in water in the presence of sodium hydroxide at a temperature comprised between 30.degree. C. and 100.degree. C.;(b) neutralizing the solution thus obtained and then freeing it from the unconverted phenol by steam distillation or extraction with a water-immiscible organic solvent and then subjecting it hot under a pressure of oxygen, to a catalytic decarboxylating oxidizing degradation in the presence of sodium hydroxide;(c) allowing the aqueous solution so-obtained, after removal of the catalyst by filtration, and then concentration hot under vacuum to 60% plus or minus 10% of its initial volume, to crystallize; and(d) draining the precipitated crystals, washing them and then drying them to constant weight under vacuum of 1 mm of mercury at 20.degree. C., to obtain sodium paraformylphenolate crystallized with 2 molecules of water or dried to constant weight under a vacuum of 1 mm of mercury at 100.degree. C. to obtain it in anhydrous form. The product is useful for preparing parahydroxy benzaldehyde quantitatively and without other purification reactions.
