Standard Test Methods for Detergent Alkylate (Withdrawn 2023)

Abstract

These test methods cover various procedures that are applicable to detergent alkylate, which comprises alkylbenzenes, in order to evaluate properties pertinent to the characterization of the alkylbenzene with respect to its suitability for desired uses. Reagent grade chemicals or any other reagent of sufficiently high purity shall be used in all tests which shall be handled with care. These test methods include the doctor test, sediment sampling and estimation using Nessler tubes, and the methods for determining the following physical properties: flash point; water or moisture content; specific gravity which include procedures using the specific gravity balance, hydrometer, pycnometer, and vacuum pycnometer; color; viscosity; aniline point; kauri-butanol value; refractive index; bromine number; and acid wash color.

Scope

1.1 These test methods cover the various test methods that are applicable to alkylbenzene in order to evaluate those properties pertinent to the characterization of the alkylbenzene with respect to its suitability for desired uses.

Note 1Detergent alkylate comprises alkylbenzenes prepared by varying processes, of varying alkyl chain configuration and length. The alkylate is sulfonated for surfactant use, the largest application being in detergent products. Careful control of detergent alkylate characteristics is desired, for along with sulfonation procedure, variations of the sulfonate can ensue that may result in either desirable or undesirable end-use properties.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For a specific hazards statement, see Section 4.
