A new family of sulfonate surfactants, in which the sulfonyl group is attached to one of the alkyl chains, has gained interest owing to their biodegradability, low sensitivity to water hardness, foaming ability, and lower skin irritability than the conventional alkylbenzene sulfonate.

一个新家庭的盐表面活性剂，sulfonyl集团隶属于链条之一，已获得利息烷基是由于它们生物降解性、低敏感性对储层水硬度、发泡能力和较低的皮肤过敏性比传统的烷基苯磺酸盐黄。

The results of technological experiment show that sulfuric acid/2-naphthalenesul phonic acid/ sulfurous acid can be efficiently separated with three adsorption towers in series, and the resin has a better reproducibility.

在此基础上进行了工艺实验研究，结果表明采用三塔串联可有效实现硫酸-2-萘磺酸-亚硫酸的分离，且树脂具有较好的重复性。

It was found that sulfuric acid, 2-naphthalenesulphonic acid and sulfurous acid could be effectively separated by competitive exchange adsorption in views of action force difference of the components with the resin. The exchange adsorption dynamic diffusion parameters were calculated with diffusion equation for solids and liquid films, and the rate-determining step was determined. The model of breakthrough curve for the resin bed was suggested, and applied to simulate the breakthrough process for each component.

通过单组分、双组分和多组分平衡数据的测定，发现对于硫酸-萘磺酸-亚硫酸混合体系，可以利用不同组分与树脂作用能的不同，通过竞争交换吸附实现分离；以固相扩散方程和液膜扩散方程对交换吸附动力学参数进行了估算，确定了交换吸附过程的控制步骤；建立了床层穿透曲线模型，并对各组分穿透过程进行了模拟。

The effect of additives on the control of crystal size for sodium sulphate is discussed in the paper.

研究结果表明：十二烷基苯磺酸钠的加入增大了硫酸钠结晶过程的界面能，从而抑制自发成核过程的发生，促进晶体的生长，改善晶体的粒度。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
