PREPARATION PROCESS OF ACRYLAMIDE CRYSTALS

Acrylamide crystals are prepared from an aqueous solution of acrylamide by causing the aqueous solution and a coolant to flow inside each electrolyticallypolished cooling tube of a double-walled or shell-and-tube heat exchanger and outside the cooling tube, respectively, instead of relying upon vacu...
