PROBLEM TO BE SOLVED: To provide a method for producing epichlorohydrin from dichloropropanol, which maintains high epichlorohydrin selectivity without necessitating an operation, such as stripping of a reaction medium or extraction, for taking out epichlorohydrin immediately after formation.SOLUTION: The method for producing epichlorohydrin comprises: a) a step of reacting a mixture of 1,3-dichloro-2-propanol and 2,3-dichloro-1-propanol, in which the content of the 1,3-dichloro-2-propanol is 10 wt.% or more, with at least one basic compound in a liquid reaction medium in order to form epichlorohydrin and a salt; and b) a step of subjecting at least a portion of the liquid reaction medium of the step a) to a settling operation in which at least a first fraction containing most of the epichlorohydrin that was contained in a part of the reaction medium of the step a) before the settling operation and a second fraction containing most of the salt that was contained in a part of the reaction medium of the step a) before the settling operation are separated. |
