The invention provides a method for detecting the content of alpha-dihydric alcohol in an epoxy resin. The content of alpha-dihydric alcohol is effectively and quantificationally detected through generating iodic acid through reacting alpha-dihydric alcohol with periodic acid, generating benzyltrimethylammonium dichloroiodate through reacting iodic acid with benzyltrimethylamine, and titrating with indirect iodimetry. Simultaneously a certain mass of glycol is weighed and is subjected to confirmatory experiments with the same method, and the theoretical value is found to be basically consistent with the practical value, so the feasibility of the method is confirmed. The method has an important guiding significance for controlling the technical production of resins.
