Abstract
This audit presents the modification to the dehydration stage of the chloral manufacturing. Chloral synthesis is achieved by ethanol and chlorine reaction. The resulting product which is approximately 80% chloral is then dehydrated using a solvent. The conventional process uses concentrated sulfuric acid (oleum) for dehydration. The sulfuric acid in the conventional process is separated after the distillation step and then rejected. The solvent in the low-pollution process is recycled after distillation. The chloral is separated from chlorinated by-products which are used by the plant, and from water which is slightly acidic.
