1.1 These test methods cover chemical and physical tests applicable to linear detergent alkylates, evaluating those properties which characterize linear detergent alkylates with respect to its suitability for desired uses.
Note 1: Linear detergent alkylates comprises linear alkylbenzenes prepared by varying processes of varying linear alkyl chain length. The alkylate is sulfonated for surfactant use, the largest application being in detergent products. Careful control of linear detergent alkylate characteristics is desired; during sulfonation, variations of the sulfonate can occur that may result in either desirable or undesirable end-use properties.
1.2 The test methods appear as follows:
|
