抄録

Although sodium lauryl sulfate is little soluble in organic solvents for IR determination, high molecular weight amine is attempted to utilize for the solvent extraction method and employment has been found to be applicable as a new determination method by solution method. A quantitative extraction with 5% CS2 solution of Amberlite LA-2 is found to be capable, followed by the determination at 1194cm-1 as a key band. By this method, even if sodium chloride, sodium sulfate and Tween 40 are present in an equivalent amount to sodium lauryl sulfate, they will not interfere with the determination, and in the case of coexistence of sodium lauryl benzene sulfonate, both components are determined quantitatively at 1250cm-1 and 1164cm-1, key bands, respectively as a binary system.
