The acetone was introduced into the continuous reactor (1) at a flow rate of 8000 L / h,Control the reaction temperature of 2°C ~ 17°C , the conversion rate of 20% to 25%The effluent is fed into the distillation column (2), the tank temperature is 92°C to 100 ° C,Tower top temperature of 55°C ~ 64°C , the top of the acetone flow 5800L / h,The tower material is fed at a flow rate of 2200 L / h into the secondary distillation column (3)Tower temperature of 92°C ~ 100°C , the top temperature of 55°C ~ 64°C ,Secondary distillation tower top acetone reflux 320L / h,The initial product of the ketone diacetone alcohol enters the distillation column at a flow rate of 1900 L / h (4)The tower temperature is 98°C ~ 100°C , the tower top temperature is 62°C ~ 64°C ,Distillation tower diacetone alcohol product flow 1800l / h, top of the acetone reflux 100L / h.The distillation of the distillation column (1), the secondary distillation column (2) and the distillation column (4) The reaction is continued in the reactor (1). The device runs continuously for 168 hours,Continuous extraction of 99.60% to 99.85% of diacetone alcohol.
