PROBLEM TO BE SOLVED: To obtain dichloropropanol having a low content of high boiling compounds. SOLUTION: This method for producing dichloropropanol is provided by using a pseudo azeotropic composition consisting of substantially dichloropropanol, hydrogen chloride and water, or preferably the pseudo azeotropic composition containing 43-63 mass% water, 23-43 mass% 1,3-dichloropropan-2-ol and 4-24 mass% hydrogen chloride.
