ISO 6384:1981 表面活性剂 工业乙氧基化脂肪胺 分析方法

On separate test portions the following determinations are carried out: measurement of the apparent pH in methanolic medium; determination of the water content; determination of the distribution of primary, secondary and tertiary amines contents; determination of oxyethylene groups content; determination of sulphated ash. Furthermore an aqueous or methanolic solution of a test portion is prepared and the free polyethylene glycols are isolated. On the separated polyethylene glycols the absence of nitrogen is verified and their relative molecular mass is determined.

ISO 4326:1980 非离子表面活性剂 聚乙氧基化衍生物 羟值的测定 乙酐法

The hydroxyl group is esterified by acetic anhydride in pyridine solution. The excess of acetic anhydride is hydrolized with water. The acidity which appears during the esterification and the acetic acid formed during the hydrolysis are neutralized by sodium hydroxide solution in the presence of phenolphthalein as indicator. The hydroxyl value is calculated from the difference between the volume od sodium hydroxide solution used for the titration of the blank and of the test solution.

The hydroxyl groups are esterified by phthalic anhydride in pyridine solution. The excess of phthalic anhydride is hydrolyzed with water containing in the sodium hydroxide solution used for the neutralization. The acidity which appears during the esterification and of the phthalic acid formed during the hydrolysis is neutralized by sodium hydroxide solution in the presence of phenolphthalein as indicator. The hydroxyl value is calculated from the difference between the volumes of sodium hydroxide solution used for the titration of the blank and of the test solution.

ISO 4311:1979 阴离子和非离子表面活性剂 临界胶束浓度的测定 用平板、镫形环或圆环测定表面张力的方法

The method is carried out in the following way: Determination of the surface tension of a series of solutions whose concentrations bracket the critical micellization concentration. Plotting of the graph of surface tension as a function of the logarithm of the concentration: the critical micellization concentration corresponds to a singular point on this curve. In this point the curve shows a sharp change of slope.

ISO 6122:1978 表面活性剂 工业烷烃磺酸盐 总烷烃磺酸盐含量的测定

A test portion is dispersed in a sodium sulphate solution, and mixture of butan-l-ol and acetons is added to precipitate sodium sulphate decahydrate and part of sodium chloride. A mixture of alkane sulphonates (mono + di), which may be contiminated by a little sodium chloride is obtained by filtration. The solvent is evaporated so that the small quantities of paraffins are eliminated. The alkane sulphonates content is determined gravimetrically and any sodium chloride present is determined potentiometrically.
