| Abstract: | Glycerol recovery technology is studied in one-step synthesis of fatty nitriles from fats. With low tempreture nitrilization catalyst and fraction condensation, industrial grade glycerol of concentration greater than 85% is recovered at 230℃~270℃ with circulating NH3 flow rate of 1 000 L/hkg . The total yield is greater than 90%. After vacuum distillation, high quality industrial grade glycerol is recovered with total yield of 85%~90%. |
