description This method for producing a high-purity 1,3-butylene glycol includes: a step for heat-treating a preparation fluid containing 1,3-butylene glycol; a step for removing, by distillation, a low-boiling-point substance included in at least the treated fluid or the treated vapor which has been subjected to the heat-treatment. The content of the base in the preparation fluid in the heat treatment step is less than 0.2 mass%.
