Method for separating mandelic compounds in salified form and use of same for preparing aromatic aldehyde |
| abstract |
The invention describes a method for separating a mandelic compound in salified form from an aqueous reaction medium resulting from the condensation reaction of a hydroxylated aromatic compound with glyoxylic acid in a basic medium, said method comprising a) decanting said reaction medium in such a way as to recover an organic phase formed from the excess of said aromatic compound and an aqueous phase formed from said mandelic compound and a quantity of the excess of said aromatic compound and b) bringing said aqueous phase into contact with an adsorbent support, resulting in the selective adsorption of said aromatic compound and the recovery of an aqueous flow comprising said mandelic compound in salified form, which is subjected to an oxidation step before being converted into hydroxyaromatic aldehyde by electrodialysis. |
