摘要
在双氰胺与甲醛的缩合反应中引入尿素[量比n(双氰胺及尿素)n∶(氯化铵)n∶(甲醛)为1.00∶.62∶.0],可降低产品成本而又不影响产品性能,为印染废水的脱色提供了一种新的产品.
The product cost may be decreased by adding urea in the dicyanodiamide-formaldehyde condensation[n（dicyanodiamide and urea）：n（ammonia chloride）：n（formaldehyde） was 1.0：0.6：2.0]. The quality of the product was not affected. A new product was given for the color removal of the dyeing and printing wastewaters.
