Process for preparing 4-hydroxyphenylacetic acid
A process for preparing 4-hydroxyphenylacetic acid by reducing 4-hydroxymandelic acid in a reaction medium of a lower aliphatic carboxylic acid or a water-containing lower aliphatic carboxylic acid. When the crystalline 4-hydroxymandelic acid is employed as the staring material, 4-hydroxyphenylaceti...

| Zusammenfassung: | A process for preparing 4-hydroxyphenylacetic acid by reducing 4-hydroxymandelic acid in a reaction medium of a lower aliphatic carboxylic acid or a water-containing lower aliphatic carboxylic acid. When the crystalline 4-hydroxymandelic acid is employed as the staring material, 4-hydroxyphenylacetic acid of high quality is obtained in high yields. |
