Method of regeneration of spent 20 to 50 per cent nitric acid |
| abstract |
This invention relates to chemical technology, in particular, to methods for regenerating spent 20-50% nitric acid obtained in the production of para-nitrobenzoic acid (p-NBC). The purpose of the invention is to increase the degree of regeneration. The method of regeneration of spent 20-50% nitric acid in the production of para-nitrobenzoic acid includes cooling and passing the spent acid through a layer of activated carbon type SKT with a ratio of the volumes of coal to solution equal to 1: (10 รท 110). 1 tab. |
