| titleOfInvention | A kind of method that triazole circulating mother liquors of 1H 1,2,4 are recycled |
| abstract | A kind of 1H 1, the method that 2,4 triazole circulating mother liquors are recycled, it is that triazole circulating mother liquor is filtered to the impurity insoluble in mother liquor by flame filter press, mother liquor after filtering is separated by standing, crystallizing, precipitating a period of time, then by triazole crystallization with clear liquid；, through decolouring, dehydration, crystallisation by cooling, centrifugation and drying, triazole will be reclaimed after triazole crystallization water dissolves；Clear liquid carries out rectifying by the rectifying column or continuous rectifying tower in gap, first separation water at ambient pressure, separates formamide at reduced pressure conditions, then with superheated vapour is distilled to recover triazole under reduced pressure.The present invention is because using as above PROCESS FOR TREATMENT circulating mother liquor, circulating mother liquor per ton can reclaim 200 300kg formamides, 250 350kg triazoles, can accomplish not discharge mother liquor externally, can both increase economic efficiency, three waste discharge can be reduced again. |
