ABSTRACT:
A crystallized sodium orthohydroxymandelate-phenol-water complex, its preparation process in which phenol (P.sub.2) is introduced into an aqueous solution S at a pH comprised between 7 and 9.5 in order to obtain the expected product which is crystallized, the aqueous solution S being such as that resulting from the reaction of phenol (P.sub.1) with glyoxylic acid in the presence of a tertiary amine and of a trivalent cation, then treatment using a solution of an alkaline hydroxide, use of this complex for the preparation of sodium orthohydroxymandelate (NaOHM), preparation process for the latter from the starting complex.
