Method for preparing sulfamate water reducing agent by using DCB waste liquid byproduct and sulfamate water reducing agent
The invention provides a method for preparing a sulfamate water reducing agent by using DCB waste liquid byproducts and the sulfamate water reducing agent, by using the method disclosed by the invention, aniline and benzidine byproducts in DCB acid waste liquid can be recovered, and the sulfamate water reducing agent is synthesized by using the recovered byproducts as raw materials. The recycling of the organic byproducts in the DCB acid waste liquid is realized, the waste is turned into wealth, and the economic benefit is relatively good.
本发明提供了一种利用DCB废液副产物制备氨基磺酸盐减水剂的方法及氨基磺酸盐减水剂，通过本发明公开的方法能够将DCB酸性废液中的苯胺类和联苯胺类副产物回收，并利用回收的副产物为原料合成一种氨基磺酸盐减水剂，实现了DCB酸性废液中有机物副产物的再利用，变废为宝，具有较好的经济效益。
