1、Designation: D 1569 05Standard Test Methods forDetergent Alkylate1This standard is issued under the fixed designation D 1569; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indica
2、tes the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 These test methods cover the various test methods thatare applicable to alkylbenzene in order to evaluate thoseproperties pertinent to the characterization of the
3、 alkylbenzenewith respect to its suitability for desired uses.NOTE 1Detergent alkylate comprises alkylbenzenes prepared byvarying processes, of varying alkyl chain configuration and length. Thealkylate is sulfonated for surfactant use, the largest application being indetergent products. Careful cont
4、rol of detergent alkylate characteristics isdesired, for along with sulfonation procedure, variations of the sulfonatecan ensue that may result in either desirable or undesirable end-useproperties.1.2 This standard does not purport to address all of thesafety concerns, if any, associated with its us
5、e. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.
