Recovery of ammonia in the dipeptide manufacturing processes

An example of an improvement in recovering ammonia in a dipeptide manufacturing process is described. The synthetic method, which makes use of the ammonolysis reaction, has been studied and found to produce dipeptides of satisfactory quality in high yield on a large scale. However, the treatment of unreacted ammonia in the ammonolysis reaction caused a reduction in the productivity and increased the production cost during actual manufacture. Therefore, a method to recover the unreacted ammonia has been investigated through simulations and trial runs using model solutions. Consequently, the modified process provided an improvement in the productivity and cost savings. In addition, the recovered ammonia could possibly be used for recycling. It was verified in a lab experiment that the reused ammonia did not lower the quality of the dipeptide.
