PROBLEM TO BE SOLVED: To efficiently produce 1,3,5 trioxane and suppress the production of by-products. In a method for producing 1,3,5 trioxane using a reactive distillation column equipped with a reactor and a distillation column, from a solution containing 1,3,5 trioxane at the bottom of the distillation column, 1,3 , 5 Trioxane is recovered. Furthermore, the recovery method is azeotropic distillation, and 1,3,5 trioxane present in the bottom of the distillation column is recovered in the reactive distillation column. is there. Moreover, it is the continuous manufacturing method of 1,3,5 trioxane characterized by returning the bottom liquid of the distillation tower after collect | recovering to a reactor.
