Problems solved by technology

The waste liquid is directly separated through the chiral membrane, and the impurities in it will affect the selectivity and flux of membrane separation. However, the combination of multiple processes through step-by-step purification increases the process steps and equipment, and the cost of waste liquid separation and purification is recovered. High, cannot be applied on a large scale

Description

technical field [0001] The invention belongs to the technical field of separation and purification devices, in particular to an integrated device for purification and chiral separation of chiral compound waste liquid. Background technique [0002] Chirality is a ubiquitous phenomenon in nature. There are many natural and synthetic chiral compounds, such as amino acids and sugars, which are also chiral molecules. Since optically active compounds are closely related to their biological and pharmaceutical activities, research on effective methods for the separation and preparation of optically active compounds has attracted extensive attention. Among them, the chiral resolution method of enantiomers is included, that is, the racemate is resolved into pure enantiomers under the action of chiral auxiliary agents. The industrial large-scale chiral resolution of racemates is the key to the preparation of chiral compounds. [0003] Membrane separation is a new energy-saving techno...
