Process for the isolation of a solid salt of p-hydroxymandelic acid; some salts of p-hydroxymandelic acid |
| abstract |
A process for the isolation of a solid salt of p-hydroxymandelic acid, which process comprises reacting phenol with glyoxylic acid in the presence of sodium or potassium hydroxide, acidifying to a pH less than 3, extracting the resulting solution with a water-immiscible solvent to provide a solution of p-hydroxymandelic acid and precipitating the salt therefrom; solid ammonium or substituted ammonium salt of p-hydroxymandelic acid. |
