Summary:Process for the preparation of pure 5-hydroxymethylfurfural (HMF) by thermal degradation of a saccharide in substantially anhydrous medium or in aqueous medium, in the presence of an acid catalyst, characterised in that the HMF formed is separated from the reaction mixture during its formation by steam distillation with superheated steam. Procédé de préparation de 5-hydroxyméthylfurfural (HMF) pur par dégradation thermique d'un saccharide en milieu sensiblement anhydre ou en milieu aqueux, en présence d'un catalyseur acide, caractérisé en ce que le HMF formé est séparé du milieu réactionnel au cours de sa formation par entraînement à la vapeur surchauffée.
