| titleOfInvention | Method of producing 2,6-dioxypiperazine |
| abstract | The invention concerns substituted piperazine, in part, the production of 2,6-dioxopiperazine (DSP), which can be used for the synthesis of: an antitumor drug, tropozone, as well as polymers and auxiliaries in the textile industry. To increase the yield of DPI and simplify the process, it is carried out by heating iminodiacetic acid with formic acid ammonium at 150-170 ° C and a molar ratio of these substances 1: 3 in an organic solvent medium (dimethylformamide or sulfolane) with the gradual removal of the decomposition products. These conditions provide an increase in DOP yield from 15 to 52%. 1 z.ts. f-ly. |
