Method for distilling ammonia |
| abstract |
The present invention relates to an improved process for distilling ammonia from a mixture, more particular from a mixture resulting from the reaction between aminonitrile and water (which reaction is also called cyclizing hydrolysis). The process for distilling the ammonia contained in an aqueous caprolactam solution, uses a column with a bottom temperature less than or equal to 160° C. and at an absolute pressure less than or equal to 5 bar, the ammonia distilled at the top of the column being compressed to a pressure greater than or equal to 10 bar and then condensed at a temperature of 25° C. to 60° C. |
