Abstract—The chlorohydrination of allyl chloride with chlorine in water was studied at 20–80°C. The effect
of the concentration of chloride ions within the range 0–3.6 mol/l on the selectivity of formation of glycerol
dichlorohydrins was studied. An equation that relates the selectivity and the concentration of Cl^– was derived,
which adequately describes experimental data. The schemes of parallel and consecutive reactions occurring in
the system were suggested. The ratios between the rate constants of the following reactions were found: the
reactions of chlorine with water and allyl chloride dissolved in water (k₁/k₄ = 4.1 10^–4), the reaction of allyl
chloride with hypochlorous acid and the decomposition of hypochlorous acid (k₂/k₃ = 1.7 10³), and the reac-
tions of the allyl chloride–chlorine complex with a water molecule and Cl^– (k₅/k₆ = 2.9 10^–2).
