In this study, the CPE processes of four different kinds of polyaromatic hydrocarbons, acenaphthene, anthracene, phenanthrene a...

今利用两种聚醚型有机硅表面活性剂DC-193和DC-190，对蒽、菲、芘和苊四种多环芳烃进行浊点萃取研究，分别使用加热、加盐、离心和搅拌等辅助方法改变相分离过程的速度。

It is useful to reduce the occurance of acid mist by adding erosion retardant and surface activity into acid which has been used in some industries.in the developed province and city, the bureau for enviroment protection calls on all enterprises to process the heated zincification water and prohibit from drainage, all enterprises should process the rinsed waste water and plating-aid waste water,however it remains to be strengthened across the country for the process of three wastes come from heated zincification

在酸中添加缓蚀剂和表面活性剂可以减少酸雾的产生，已在一部分企业中得到应用。在发达省市，环保部门要求企业必须对热镀锌废水进行治理，不得外排，企业对漂洗废水、助镀废液均进行处理，但全国范围内对热镀锌的三废治理还需加强。

Their structures were confirmed by IR, and the properties of these surfactants such as acid number, interfacial tension, and critical micelle concentration and so on were studied.

通过红外光谱确定了产物的结构，并对有机硼表面活性剂的酸值、表面张力以及临界胶束浓度等性能进行了研究。

The tests show that it has effective broad spectrum bactericidal action and good compatibility with ionic or/and nonionic surfacants at concentration of 0.02-0.05%. It is really toxicless and effective in the range of pH value for cosmetics .

实验证明：Kathon CG对细菌、酵母菌和霉菌具有广谱抗菌活性；使用浓度为0.02~0.05%；可与所有离子型、非离子型表面活性剂配伍；在含有蛋白质的化妆品中的用重要加大；在化妆品中一般所遇到的pH范围都有效；在使用量下无毒。

N—acyl—ED3A is a new type of surfactant.

N—酰基ED3A 是一种新型的表面活性剂。

M is, the higher the strength will be, as well as more even particle distribution. The mechanism of additives as discussed revealed that on the surface of Al_3 particles the oleophilic group of surface active agent will form oil films to bind together fine Al_3 particles closely so as to increase both the particle size and strength.

结果表明，氢氧化铝颗粒在 45～105μm的个数百分数越大，氢氧化铝颗粒分布越均匀，强度就越好；探讨了添加剂的作用机理，即表面活性剂分子的亲油基在氢氧化铝粒子表面形成油层，将氢氧化铝细粒子紧密粘结在一起，使氢氧化铝的粒度与强度增大。

A novel anionic gemini surfactant,didodecyl-ethoxylate bis-sodium sulfate was prepared in three steps using lauryl alcohol,glycol-epiglyceride and chlorosulfonic acid as raw materials and BF_3-ethyl ether as catalyst.The chemical structure of the product was confirmed by IR spectrum.

以十二醇、乙二醇二环氧甘油醚和氯磺酸为原料，以BF3-乙醚为催化剂，通过三步法制备阴离子型双子表面活性剂双十二烷基乙氧基二硫酸酯钠；红外光谱对其结构进行了表征，测定了其表面活性和发泡力等性能。
