GB/T 9290-2008Surface active agents -- Technical ethoxylated fatty amines -- Method of analysis (English PDF)

Foreword

This standard replaces the national standard GB/T 9290-1988 "surfactant industry ethoxylated fatty amines analytical methods." this standard and ISO 6384. 1981 "surfactant industry ethoxylated fatty amines analysis methods," the degree of non-conformity Equivalent.

This standard and ISO 6384. 1981 is the main differences.

--- International standard "Determination of sulfated ash" section only wrote a number of international standards. This standard is based on China's reality, stated principles, Reagents and materials, equipment and facilities, as well as the results of the analysis step.

--- The International Standard "Water - methanol pH measurement media" section in the 'note' to the contents of the text.

--- The international standard of "total alkalinity, primary amine, secondary amine alkalinity, tertiary" in the title to "total amine value, the value of a primary amine, secondary amine value, Tertiary amine value. " this standard and GB/T 9290-1988 compared to the major differences are as follows.

--- Increasing the test report chapter.

Surfactant Industry ethoxylated fatty amine Analytical method

1 Scope

This standard specifies the surfactant industry ethoxylated fatty amines analysis. It includes the following determination. Water - measuring methanol pH of the medium Measuring the oxygen content of the vinyl;; set; determining moisture content; determination of sulfated ash; determination of primary amine value, secondary amine value, the value of the distribution of free tertiary Determination of the content of polyethylene glycol; polyethylene glycol test.

This standard applies to flake, block, paste or liquid ethoxylated fatty amine industrial analysis, but does not contain any substance and manufacturer-independent quality. It does not apply ethoxylated amines and amide derivatives of imidazoline class.

Analysis of the product structure of the general formula.

(CH2CH2O) m1 H

(CH2CH2O) H-shaped

R --- saturated or unsaturated aliphatic group, a chain length of 8 to 22 carbon atoms.

M1 + --- shape may take any value in accordance with the product's use, but it is usually 1-50 change.
