Abstract
The distillation apparatus includes a rectifying column, a reflux condenser and a product condenser. The reflux condenser communicates directly with the interior of the rectifying column in order to return condensed reflux at or near its boiling point. The product condenser is connected to the output of the reflux condenser to condense the product vapors passing from the reflux condenser to obtain a product of high purity.
