Gas-liquid chromatography and viscometry were used to study the intermolecu
lar interaction of fenvalerate with petroleum sulfoxides and sulfones in th
e temperature range from 50 to 65 degreesC. The calculated thermodynamic pa
rameters of the interaction were presented as functions of the composition.
The highest deviations from additivity were observed at the equimolar rati
os of the components. The coordination centers of interacting molecules wer
e detected by H-1 NMR spectroscopy.
