| titleOfInvention | Method for preparing ammonium dihydrogen phosphate from wastewater generated in production of methyl cedryl ketone and methyl cedryl ether |
| abstract | The invention relates to the field of fine chemicals, and provides a method for preparing ammonium dihydrogen phosphate from wastewater generated in the production of methyl cedryl ketone and methyl cedryl ether. Sending the acidic wastewater generated in the production process of the methyl cedryl ketone into a reaction tank, and directly introducing ammonia gas into the reaction tank to adjust the pH value to be neutral; under the action of aeration, the floating oil floating on the liquid surface is sucked into the reaction kettle by vacuum, and the methyl cedryl ketone is recovered by decompression; and (3) the wastewater after the reaction is saturated ammonium dihydrogen phosphate solution and a solid ammonium dihydrogen phosphate crude product, and then the wastewater is recrystallized, mother liquor is recycled and dried to obtain a finished product ammonium dihydrogen phosphate. The method utilizes a large amount of acidic wastewater generated in the process of producing the methyl cedryl ketone and waste gas generated in the process of producing the methyl cedryl ether to recover the methyl cedryl ketone and prepare ammonium dihydrogen phosphate; the ammonium dihydrogen phosphate byproduct can be used as a raw material of a dry powder fire extinguisher, can also be used as a phosphate fertilizer and a nitrogen fertilizer, and has wide application. The invention effectively recycles resources and has strong creativity. |
