| titleOfInvention | A kind of Recycling Mother Solution of producing terephthalaldehyde applies mechanically technique |
| abstract | The Recycling Mother Solution of producing terephthalaldehyde applies mechanically a technique, comprises the steps: that (1) gets appropriate p-Xylol and chlorine carries out chlorination reaction; (2) add nitric acid and water to be hydrolyzed reaction; (3) be separated to obtain filtrate and filter cake, filter cake, after once washing, soda ash and secondary washing process, carries out centrifugal, dry, obtains terephthalaldehyde finished product; (4) in step (3), a water lotion recovery of filtrate and filter cake adds silver carbonate, stirring reaction 1h, and filter, filtrate enters in step (2) again.Recycling Mother Solution of the present invention applies mechanically technique, the mother liquor reacted is added certain silver carbonate stir, hydrochloric acid in removing mother liquor, reach the object that mother liquor repeats to apply mechanically, often produce the waste water that 1 ton of terephthalaldehyde only can produce 2-3 ton, greatly reduce the quantity discharged of waste water, in mother liquor, remaining nitric acid is fully used, the muriate wherein produced can also recycle and sell, thus reduces production cost. |
