The invention concerns a continuous method for producing chlorhydrine which consists in reacting a polyhydroxylated aliphatic hydrocarbon, a polyhydroxylated aliphatic hydrocarbon ester or a mixture thereof, with a chlorinating agent and an organic acid in a liquid reaction medium whereof the composition in stationary state comprises polyhydroxylated aliphatic hydrocarbon and polyhydroxylated aliphatic hydrocarbon esters and whereof the sum of the contents expressed in mole of polyhydroxylated aliphatic hydrocarbon is higher than 1.1 mole % and not more than 30 mole %, the percentage being relative to the organic part of the liquid reaction medium.
Procédé continu de production de chlorhydrine dans lequel on fait réagir un hydrocarbure aliphatique poly hydroxylé, un ester d'un hydrocarbure aliphatique poly hydroxylé ou un mélange d'entre eux, avec un agent de chloration et un acide organique dans un milieu réactionnel liquide dont la composition à l'état stationnaire comprend de l'hydrocarbure aliphatique poly hydroxylé et des esters de l'hydrocarbure aliphatique poly hydroxylé dont la somme des teneurs exprimée en mole d'hydrocarbure aliphatique poly hydroxylé est supérieure à 1,1 mol % et inférieure ou égale à 30 mol %, le pourcentage étant rapporté à la partie organique du milieu réactionnel liquide.
