| titleOfInvention | Method of utilising toxic chlorine-containing substance 2-(2-chlorobenzylidene)malonodinitrile(cs) |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to methods of destruction of toxic substances, namely to utilisation of toxic chlorine-containing substance 2-(2-chlorobenzylidene)malonodinitrile(CS) with obtaining 2-chlorobenzoic acid, which is a marketable product for synthesis of various organic compounds: pesticides, dyes, medications. Method consists in boiling 2-(2-chlorobenylidene)malononitrile in water solution of potassium permanganate for 3-3.5 hours. After that, mixture is kept at room temperature for 14-16 hours, obtained sediment is washed with hot water. Filtrate is evaporated, acidified with 10-15% hydrochloric acid, sediment from filtrate is washed with water and re-crystallised to obtain 2-chlorobenzoic acid. n EFFECT: invention makes it possible to eliminate toxic reagents from technological process and harmful emissions into atmosphere. n 2 ex |
