摘要
以 β -萘磺酸甲醛缩合物钠盐为原料 ,通过离子交换树脂法制备了六种不同结构的季铵阳离子所对应的萘磺酸甲醛缩合物盐 。
Using sodium β-naphthalenesulfonate-formaldehyde condensate as raw material,six kinds of β-naphthalenesulfonate-formaldehyde condensates with different quaternary ammonium ions were prepared by means of dowexing.The experiments were carried out on their effects on the properties of cement concrete.
