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, alkalinity primary amine, secondary amine alkalinity, 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. The standard proposed by China Petroleum and Chemical Industry Association. This standard is under the jurisdiction of Chemical Industry Standardization Technical Committee surfactant. This standard was drafted. Shanghai Dyestuffs Research Institute Co., Ltd., Zhejiang Real Chemical Group. Drafters of this standard. Xusu Mei, is Qi Gu, Wangwei Song, Meng Zhaoping. This standard was first published in 1988. 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. R N (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.
