NOVELTY - Producing hexafluorobutadiene involves mixing adsorption resin, aqueous oxidized graphene solution, potassium borohydride and water in weight ratio of 100:2-10:0.05-0.5:300-1000 at 50-100 degrees C for 30-80 hours, and then filtering the mixed solution to obtain filtrate. The specific surface area of adsorption resin is 500-1000m2/g. The filtrate is dried in presence of nitrogen, and then calcined at 200-400 degrees C for 1-3 hours. The obtained product is roasted at 500-800 degrees C for 1-5 hours, and further roasted at 900-1200 degrees C for 1-5 hours. USE - Method for producing hexafluorobutadiene (claimed). ADVANTAGE - The method enables to produce hexafluorobutadiene with high purity. DETAILED DESCRIPTION - Producing hexafluorobutadiene involves mixing adsorption resin, aqueous oxidized graphene solution, potassium borohydride and water in weight ratio of 100:2-10:0.05-0.5:300-1000 at 50-100 degrees C for 30-80 hours, and then filtering the mixed solution to obtain filtrate. The specific surface area of adsorption resin is 500-1000m2/g. The filtrate is dried in presence of nitrogen, and then calcined at 200-400 degrees C for 1-3 hours. The obtained product is roasted at 500-800 degrees C for 1-5 hours, and further roasted at 900-1200 degrees C for 1-5 hours. The roasted product is cooled to room temperature to get efficient adsorbent. The efficient adsorbent is processed in an adsorption tower at 0-30 degrees C and 0.1-1MPa. The vacuum distillation of obtained product is carried out to remove impurities to obtain the final product i.e. hexafluorobutadiene.
