Determination of dispersing power of surfactants
1 Scope
This standard specifies the method for the determination of the dispersibility of surfactants.
This standard is applicable to the determination of the dispersibility of anionic dispersants.
2 normative reference documents
The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article
Pieces. For undated references, the latest edition (including all modifications) applies to this document.
GB/T 6372 Samples of Surfactants and Detergents
GB/T 6682 Analytical laboratory water specifications and test methods
3 principle
In the quantitative dispersant sample and standard solution, respectively, by adding quantitative fast pigment red 3RS solution, at the same stirring speed, a
Times to add a quantitative dilute sulfuric acid solution, so that fast pigments of trans-diazonium salt quickly into cis-diazonium salt, and with the phenolic ester into insoluble azo dye
The dispersion of the dispersion of the sample, in the closed conditions, the drip filter paper diffusion circle, compare the sample and the standard size of the circle area, to calculate the dispersant dispersion
Of the percentage.
4 reagents and materials
4.1 Water specifications
The water used in this standard shall comply with the three water requirements specified in GB/T 6682.
4.2 95% ethanol
Specifications for the chemical purity.
4.3 sulfuric acid solution
c (1/2H2SO4) = 1.00 mol/L.
4.4 Sodium hydroxide solution
ωNaOH = 33%.
4.5 fast pigment red 3RS solution
Concentration of 60g/L.
Weigh the fast pigment red 3RS6g (accurate to 0.01g) in the beaker, add 95% ethanol 6mL beating, add sodium hydroxide solution
6mL, stir evenly, add 60ml water 88mL, fully dissolved, filtered into a brown volumetric flask, cooled to room temperature standby. Now with the current use.
