Abstract
Sulfides of the thiophene series boiling 180–460° are separated by gas-liquid chromatography. It is shown that treatment of the solid carrier with alkali leads to a marked decrease in retention time, the specific interaction with the stationary phase being unchanged. The thermodynamics of solution of sulfides of the thiophene series in the stationary phases, polyethyleneglycoladipate and silicone rubber, are considered. On a basis of excess heat of solution, an attempt is made to solve the problem of interaction of sulfide sulfur with the thiophene ring.
