In this investigation, the surface-chemical properties of the mixed aqueous solutions of n-octyltrimethylammonium bromide (C_8 NMe_3Br) and sodium n-octylsulfate (C_8 SNa) have been studied. Some peculiar properties have been observed: (1) there is a very high surface activity of the mixed surfactants. The cmc of 1:1 (molar ratio) mixture is 7.5×10~(-3) m(cmc of C_8NMe_3Br: 2.6×10~(-1) m). The surface and interfaeial tension of 1:1 mixture are very low—down to ~23 and ~0.2 dyne/cm, whereas those of the single...

In this investigation, the surface-chemical properties of the mixed aqueous solutions of n-octyltrimethylammonium bromide (C_8 NMe_3Br) and sodium n-octylsulfate (C_8 SNa) have been studied. Some peculiar properties have been observed: (1) there is a very high surface activity of the mixed surfactants. The cmc of 1:1 (molar ratio) mixture is 7.5×10~(-3) m(cmc of C_8NMe_3Br: 2.6×10~(-1) m). The surface and interfaeial tension of 1:1 mixture are very low—down to ~23 and ~0.2 dyne/cm, whereas those of the single ionic surfactant solution (at cmc or above) are ~40 and ~10 dyne/em, respectively; (2) the bubble-life and the drop-life of 1:1 mixture are both much longer than those of the single surfactant solution; (3) the 1:1 mixture has a much better wetting power on paraffin wax than a single ionic surfactant solution; (4) the total surface and interracial adsorptions of the non-1:1 mixture are nearly equal to those of the 1:1 mixture, in most cases the surface and interfacial tensions are very low, and the surface mole-ratio of C_8NMe_3~+ to C_8S~- approaches 1:1; and (5) there is no obvious effect upon the surface and interfacial adsorptions and cmc by adding an inorganic salt (NaBr) to the solution of the mixed surfactants. The Gibbs equation should be written as:-dγ=RTΓ_(Total)d In mC_5NMe_3~+(or C_8S-) rather than the 2RT form as applied in the case of an ionic surfactant. From this equation the minimum average "molecular" area of the surface film of 1:1 mixture has been calculated to be 27~29 ~2, which is much smaller than that of a single ionic surfactant (in general, >40~2), indicating a closer packing of the surfactant ions on the surface.The above mentioned characteristics show that there are strong interactions between cationic and anionic surfactants in the mixed solution. The nature of these interactions is essentially due to the Columbic attractions between the positive and negative charges of the surfactant ions in addition to the hydrophobic interactions between hydrocarbon chains.

本工作研究了碳氢链较短的溴化辛基三甲铵(简写为C_8NMe_3Br)及辛基硫酸钠(简写为C_8SNa)混合水溶液的一些表面化学性质:在表面及“油-水”界面上的混合吸附、在表面上的气泡寿命和在界面上的液滴寿命以及溶液在石蜡表面上的润湿性能。从这些性质了解正、负离子表面活性剂的相互作用。结果表明:(1)混合表面活性剂有很高的表面活性。1:1C_8NMe_3Br-C_8SNa混合物的临界胶团浓度(cmc)为~7.5×10~(-3)m,远小于单一表面活性剂。在此浓度时,表面张力低达~23达因/厘米;溶液-正庚烷的界面张力更低,达~0.2达因/厘米,亦远低于单一表面活性剂;(2)混合表面活性剂溶液有很高的气泡寿命及液滴寿命,亦即有较大的表面膜及界面膜强度;(3)混合溶液比单一表面活性剂的润湿性能好;(4)不同比例的C_8NMe_3Br-C_8SNa混合溶液的表(界)面总吸附量与1:1混合溶液的相近,当浓度较大时,吸附层中两者比例大多接近1:1,且表(界)面张力亦甚低:(5)与一般离子型表面活性剂的情形完全不同,无机盐对1:1混合溶液的表(界)面张力影响很小。计算吸附量时,Gibbs公式应取1RT形式,而不采用对一般离子...

On the basis of the results of experiment and research,this contribution discusses the relation between the stability of the emulsion formed in the kerosene-water system under different temperatures(with type AE non-ionic surfactant used as emulsifier)and the EO content in molecules of the surfactant.It also expounds the relation between demul- sification effect and EO content when the surfactant is used as an o/w type demulsifier.

AE 型(聚醚型非离子)表面活性剂,能形成 O/W 型乳状液。乳状液的稳定性随活性剂分子中环氧乙烷(EO)含量的增加而增大,在某一温度范围内乳状液的稳定性最好;另方面,它还可作为 O/W 型乳状液的破乳剂,其破乳效果随分子中 EO 含量的减少而增加。为了解释实验结果,本文还提出了 AE 型表面活性剂分子在煤油-水界面上的状态模型。

The polymerizationconversion and intrinsic viscosity of copolymers in high monomer concentration are greaterthan that in low monomer concentration to a certain extent. Radiation crosslinking ofcopolymer gives hydrogels having swelling ratio in water above 1,000, The swelling ratioof the copolymer-hydrogels depends not only on the crosslinking density, but also on the amountof-COONa groups in macromoleculer chains.

本文描述了丙烯酰胺—丙烯酸钠水溶液辐射共聚—交联制备共聚物水凝胶的研究。在共聚体系中加入少量非离子型表面活性剂,可把单体浓度由通常的20%上下提高到50%,聚合转化率和共聚物的特性粘数也都有相当程度的提高。这一体系经辐射共聚—交联后,可得到溶胀比>1,000的共聚物水凝胶——超级吸水材料。这种共聚物水凝胶的溶胀比不仅受吸收剂量即交联密度的制约,而且与共聚物中羧钠基的含量有密切关系。
