  surfactant
The optimal constituents of microemulsion were found from pseudoternary phase diagrams: the mass ratio of Span80 to PS was 4:1 and complex surfactant to cosurfactant was 1:1.
      
Synthesis and surface-active property of bis-quaternary ammonium-sodium sulfate Gemini surfactant
      
N,N-dimethyldodecylamine, hydrochloride and epichlorohydrin (molar ration is 2:1:1) were used to synthesize bis-quaternary ammonium Gemini surfactant with a hydroxyl in its spacer group by the one-pot method.
      
This hydroxyl was sulfonated by chlorosulfonic acid and then neutralized to bis-quaternary ammonium-sodium sulfate zwitterionic Gemini surfactant.
      
The critical micelle concentration (cmc) and surface tension of the novel zwitterionic Gemini surfactant in aqueous solution at 15°C are 7.2×10-5 mol/L and 34.5 mN/m, respectively.

This paper deals with a new method of preparing rosin chloride directly with chlorine, which is different from the traditional method as shown in relevant materials. The chlorinated rosin soap lye thus made can be used as surfactant and lubricant in place of chlorinated paraffinum, as it is characterized by its properties of better condensation and antifrication.

The effects of polyethylene glycol with different molecular weight on the surface properties such as cloud point, surface tension, critical micellar concentration, wettability emulsion, foamability, dispersing power and detergency performance of aqueous solution of polyethoxylated fatty alcohols (AEO-9, AEO-15) which were extracted from commercial polyoxyethylenated ether in removing polyethylene glycol by Weibull method were investigated. Experimental results show that there were no significant effects of the content of polyethylene glycol as usual range (tO100% of AE) to the cloud point, surface tension, wettability, emulsion, foamability of 9 and 15 etho-fatty alcohol, but the dispersing power and detergency of the mixed solution are more or less increased if the amount of polyethylene glycol added is within 10% of the surfactant. The effects of the molecular weight of poly ethyleneglycol between 600~2000 on the surface properties of the mixed solution may be negligible.

用Weibull萃取法除去脂肪醇聚氧乙烯醚产物中聚乙二醇(PEG),在制得的纯品脂肪醇聚氧乙烯醚申加入不同含量和不同分子量的PEG,测定混合物的浊点、表面张力、临界胶束浓度、润湿、乳化、泡沫、分散及去污性能。当PEG含量在通常范围内,对AE溶液的浊点、表面张力、润湿、乳化、泡沫性能无显著影响;加入量在10%以下时,能轻微提高溶液的分散性及去污率。PEG分子量大小在600~2000范围内对AE性能的影响无明显差别。

The mechanism of interaction of 1,5-bis(2 hydroxy-5-chloro phenyl)-3-cyanoformazan(HCPCF)with surfactants has been investigated by analysing the effect of surfactants on the absorption spectra and solubilization of HCPCF reagent.In acidic medium the solubilization effect of the micelle of surfactants on the molecular form of HCPCF has been shown to be dominant. On the basis of comparison of corresponding spectra solubilized HCPCF molecules are considered to be located in the hydrophobic hydrocarbon core of surfactant's micelle. In basic medium below critical micellar concentration the individual molecule of nonionic surfactants can react, with HCPCF as well as its metallic complexes in a definite ratio(2:1 in the case of Tween-80).The solubility of the compound formed is dependent on the structure of the nonionic surfactant's molecule, particularly on the number of etlylene oxide groups in the hydrophilic part.It has been postula ed that the nonionic surfactants combine with HCPCF by forming hydrogen bonds between the undissociated hydrogen atoms of HCPCF anions and the oxygen atoms of the polyethylene oxide groups of nonionic surfactan s.

通过测定表面活性剂对HCPCF吸收光谱及溶解度的影响,研究了HCPCF与表面活性剂之间的作用机理。在酸性介质中表面活性剂主要起胶束增溶作用。根据HCPCF在不同极性溶剂中的吸收光谱确定,分子形态的HCPCF是处于表面活性剂胶束的憎水碳氢链部分。在碱性介质中,在CMC以下,非离子表面活性剂可以单分子形式与HCPCF及其金属络合物形成具有一定组成比的化合物,此化合物的溶解度与非离子表面活性剂的结构有关。非离子表面活性剂可能是由其聚乙氧基的氧原子和HCPCF的尚未离解的氢之间形成氢键而反应。
