Abstract A method is given for the quantitative determination of sodium lauryl sulfate in liquid, frozen, powdered, or flake-dried egg white. The egg white is dissolved in water and the protein is precipitated with ethanol and filtered off. The filtrate is evaporated, the residue is dissolved in water, and the pH is adjusted to 5.0. Total alkyl sulfates are titrated with standard benzethonium chloride solution in the presence of chloroform with bromphenol blue indicator. Results are calculated as sodium lauryl sulfate. The formation of the bromphenol bluebenzethonium chloride complex, when excess benzethonium chloride is present, is taken as the end point. The blue-green complex is soluble in the chloroform. Overall recoveries of sodium lauryl sulfate from egg whites ranged from 94 to 100%. Collaborative study of the method is recommended.

Magnetic susceptibility measurements have shown that the chromium atoms in the toluene–chromyl chloride complex are tetravalent. The structure of the complex and the reaction mechanism are discussed. Spectroscopic evidence has been found of the initial formation of a π-complex. The products of reaction of chromyl chloride and ethylbenzene, isopropylbenzene, tetralin, and indane have been determined.
