Zusammenfassung:FIELD: fat and oil industry, chemical technology. SUBSTANCE: invention relates to production of distilled glycerol. Method involves distillation of crude glycerol under vacuum at residual pressure 2.0-2.67 kPa and temperature 175-180 C. Before distillation phenosane-28 is added to glycerol in the amount 0.2-0.3+ACU- of distilling glycerol mass. Method allows the improvement of quality of distilled glycerol and to stabilize the distillation process. EFFECT: improved method of distillation. 1 tbl, 2 ex
