Lithium dodecyl sulfate
Lithium dodecyl sulfate

Cat. No.: HY-W099535
CAS No.: 2044-56-6
Lithium dodecyl sulfate is an anionic hydrocarbon surfactant with both surface tension reduction and interfacial adsorption capabilities. Lithium dodecyl sulfate induces low surface viscosity; it forms micelles in aqueous solutions through entropy-driven (low temperature) and enthalpy-driven (high temperature) mechanisms. When acting synergistically with tetrabutylammonium bromide, Lithium dodecyl sulfate exhibits cloud point behavior due to micelle aggregation and phase separation. Lithium dodecyl sulfate can form an adsorption layer at the air-water interface with quantifiable surface excess and minimum area per molecule, and it has higher equilibrium surface tension and foamability compared to other dodecyl sulfate counterion variants. The foam stability of Lithium dodecyl sulfate above its critical micelle concentration is low, and its dynamic surface tension pattern changes dynamically with bubble frequency .

Thiomichler's ketone
Thiomichler's ketone
0 Images
Cat. No.: HY-W009311
CAS No.: 1226-46-6
Synonyms: 4,4'-Bis(dimethylamino)thiobenzophenone
Thiomichler's ketone (4,4'-Bis (dimethylamino) thiobenzophenone) is a heavy metal complexing agent and a colorimetric/spectrophotometric reagent. Thiomichler's ketone shows selectivity for Hg 2+ at pH 3, and exhibits activity towards Pd 2+ and Ag + at pH 3.5. Thiomichler's ketone enables accurate detection of trace Pd 2+ by forming an extractable Hg 2+ complex via micelle-mediated cloud point extraction, or generating a red coordination complex including Pd (TMK)4. Thiomichler's ketone is applicable for the determination of trace Pd 2+ in antibiotics and catalysts of automobile exhaust purifiers .
