Abstract
The invention is an apparatus and process for batch rectification or reaction with batch distillation. The apparatus is a rectifying column alone or mounted on a batch reactor. The rectifying column having a collector for the downflowing column liquid arranged to collect liquid flowing down the column and a valve arrangement to direct the flow selectively away from the column or to the column at a time when downflowing product is being removed from the column. The column is operated at total reflux until the product reaches a required purity then the liquid flow from the collector is directed away from the column and the product recovered.

An apparatus for carrying out batch rectification in a rectifying column or for carrying out a chemical reaction and rectification in a batch reactor surmounted by a rectifying column, the rectifying column adapted for operation under total reflux, comprising at least one rectifying column section for material transfer;
- at least one column underflow product vessel for collecting and temporarily storing a liquid which flows downward through the rectifying column section;
- an overhead product vessel for collecting and temporarily storing an overhead product;
- wherein, an arrangement is provided for selectively guiding liquid, flowing down the rectifying column section, into the underflow product vessel or away from the underflow product vessel.
