Abstract
Provided herein are processes for carrying out a chemical reaction of a substrate in a diluted reaction mixture. The processes include conducting the reaction mixture having reaction product and solvent to a filtration membrane which is permeable to the solvent but impermeable to the reaction product. Solvent which permeates the filtration membrane for dilution of the substrate feed is recycled.
Claims13
A continuous process for carrying out a chemical reaction of a substrate in a diluted reaction mixture comprising a solvent, the process comprising the steps of:
- (a) simultaneously adding a substrate feed and a solvent for diluting said substrate feed to form a reaction mixture in a reactor;
- and causing said substrate to form a reaction product in said reaction mixture;
- (b) discharging, from an outlet of the reactor, reaction mixture comprising reaction product and solvent to a filtration loop feed tank;
- discharging reaction mixture from an outlet of said filtration loop feed tank;
- (c) conducting the reaction mixture discharged from the filtration loop feed tank to a filtration membrane, wherein the filtration membrane is permeable to the solvent and provided to be impermeable to the reaction product, thereby obtaining a permeate comprising solvent and a retentate comprising reaction product;
- (d) recycling the permeate entirely for diluting said substrate feed in step (a);
- and
- (e) conducting the retentate from said filtration membrane entirely to the filtration loop feed tank.
