GB/T 17041-2012Surface active agents -- Sulfated ethoxylated alcohols and alkylphenols -- Determination of total active matter content (English PDF)

Foreword

This standard rule according to GB/T 1.1-2009 given draft.

This standard replaces GB/T 17041-1997 "surfactant ethoxylated alcohols and alkylphenols total sulfate content of the active substance Determination, "compared with the GB/T 17041-1997, the main changes are as follows.

--- Remove the ISO foreword;

--- Reducing the degree of modification using standard adoption.

This standard uses redrafted law revision of international standards ISO 6842. 1989 "surfactant ethoxylated alcohols and alkylphenols sulfur Determination of "salt of the active substance is present.

This standard and ISO 6842. 1989 and technical reasons for the difference. on normative references, this standard has made technical Adjust the difference to fit our technical conditions, adjust focus reflected in Chapter 2, "Normative references", the specific adjustment as follows.

--- Equivalents adoption of international standards GB/T 6372-2006 instead of ISO 607. 1980 (see Chapter 6);

--- Increase cited GB/T 601-2002 (see 4.5);

--- Increase cited GB/T 678-2002 (see 4.1);

--- Increase cited GB/T 686-2008 (see 4.4);

--- Increase cited GB/T 9853-2008 (see 4.3);

--- Increase cited GB/T 16983-1997 (see 4.2);

--- Increase quoted HG/T3440-1999 (see 4.6).

The standard proposed by China Petroleum and Chemical Industry Association.

This standard by the National Standardization Technical Committee Chemistry (specialty) surfactant Technical Committee (SAC/TC63/SC8) centralized.

1 Scope

This standard specifies the test methods for the active substance in the total sulfate content determination ethoxylated alcohols and phenols.

This standard applies to ethoxylated alcohols and alkylphenols sulfated product [alkyl alcohol ethylene oxide ether sulfates (ethoxylated alcohol sulfate Salt)] or alkyl phenol ethylene oxide ether sulfates (alkyl phenol ethoxylate sulfate measured) of the active substance in the total content.

The total active substances include organic compounds dissolved in ethanol (alkyl ether sulfates, alkylphenol ether sulfates,, and nonionic polyethylene glycol Component).
