SETT ATT KONCENTRERA EN VATTENHALTIG AKRYLAMIDLOSNING, SOM ERHALLITS GENOM EN KATALYTISK HYDRATISERINGSPROCESS |
摘要 |
A method for economically concentrating an acrylamide aqueous solution by catalytic hydration without substantial deterioration in the product. According to the method, an acrylamide aqueous solution obtained from catalytic hydration, is concentrated by distillation while maintaining the solution in good contact with at least 0.1 mole. or more of air per mole. of water distilled from the acrylamide aqueous solution. |
