表面活性剂

In order to improve their water solubility, 4"-fatty amido-3"-sodium carboxylate azobenzene-4-sodium sulfonates were synthesized. They are azo compounds with two hydrophilic groups of carboxyl and sulfonyl. They decrease the surface tension in dilute solution slowly, and show some surfactivity, but are not surfactants. The probable reason is their relative strong hydrophile. Furthermore, their colors are not fresh and far from our destination.

为了改善其水溶性，改用对氨基苯甲酸为原料合成了4′-脂肪酰氨基-3′-羧酸钠偶氮苯-4-磺酸钠盐，以偶氮结构为主的亲水基团上连有羧酸基和磺酸基两个亲水性较强的基团，但可能由于其亲水性太强，在稀溶液中只能缓慢地降低溶液的表面张力，具有一定的表面活性，但不是表面活性剂，而且颜色不鲜艳，距离我们的目标较远。

中文解释=一种表面活性剂，用来去除各种各样表面及物质的灰尘和油脂。

Biosurfactant is a high surface-active agent synthesized by microorganism.

烷基糖苷，100%用再生性天然原料生产，在生物、药理和生态方面高度安全，具有优越的表面活性和应用性能，可用于许多领域，代表了下一代表面活性剂的发展方向。

Hydrophobically associating water-soluble polymer-based synthesis is difficult and not easily characterized, in part to hydrophobic chains connected to the water-soluble polymer, the general use of micellar copolymerization, or the use of the large surfactant monomer to copolymerization, polymer micelles need in the system by adding a large number of surface-active agent, which, after an increase of the complexity of the process.

疏水缔合型水溶性高分子很难合成，且不易表征，把疏水部分连接到水溶性聚合物链上，一般采用胶束共聚合或者使用具有表面活性的大单体进行共聚，胶束聚合需要在体系中加入大量的表面活性剂，这就增加了后处理过程的复杂性。

It was found that surfactants showed some effects on the electron transfer reaction at thiol modified gold electrode.

阴离子表面活性剂对上述修饰电极表面的电子传输反应有一定的抑制作用。

The surface turns brown as the organic solvent and surfactant dries and burns off to produce a white or green titanium dioxide coating.

表面变成褐色的有机溶剂及表面活性剂干燥和烧伤过产生白色或绿色的二氧化钛涂层。

The new anionic gemini-type surfactants are expected to have improved surface properties, which could lead to additional economical applications.

It is convenient for sinter to be leached, and the secondary reaction appears little. The slurry after sinter leaching is transferred into autoclave for desilicification at about 170℃, and the siliceous modulus of solution reaches more than 200. Then some lime is added for deep-desilication at normal pressure, the siliceous modulus of solution increases more than 600 even if the Al2O3 content is more than 200g/L.The SiO2 coefficient in hydrate garnet from deep-desilication is more than 0.28. Under conditions of the addition of seed and application of novel technology of carbonization, the contents of Na2O and SiO2 in product are less than 0.37% and 0.025%, respectively.

实验结果显示：烧成的熟料溶出条件宽松，二次反应程度弱；溶出浆液在170℃左右直接进行加压脱硅，脱硅后溶液的硅量指数大于200，再加入适量的石灰进行深度脱硅，即使溶液中氧化铝浓度超过200g/L时，精液的硅量指数也大于600，且得到的水化石榴石中二氧化硅饱和系数大于0.28；通过加入晶种和采用新的碳酸化分解工艺制度，产品中的SiO2 含量降至0.025%， Na2O含量小于0.37%；加入表面活性剂，不仅能将碳分母液蒸发至Na2OT浓度大于300g/L，而且还可有效减缓表面上结疤的形成速度。
