The present invention is directed to a process for preparing a glycidyl sulfonate derivative with high purity and in high yield, which is characterized by reacting glycidol prepared from treating 3-chloro-1,2-propanediol in an aqueous solvent in the basic condition, without isolating the resulting glycidol with a sulfonyl halide in a two phase solvent consisting of an organic solvent and water in the presence of an inorganic base and a tertiary amine or a pyridine derivative.

Ce procédé de production à forts rendements de dérivés très purs de sulfonate de glycidyle consiste à faire réagir du glycidol, notamment un mélange de réaction contenant du glycidol et obtenu par mise en réaction de 3-chloro-1,2-propanediol dans un milieu aqueux et dans des conditions basiques, avec un halogénure de sulfonyle, dans un solvant à deux phases comportant un solvant organique et de l'eau, en présence de bases comprenant une base minérale spécifique et, soit une amine tertiaire, soit un dérivé pyridine.
