There were defined distribution constants K_с in interval of temperatures 25–75С on which basis appeared the conclusion that alcohols С1–С3 can be used as water (non-partitioning) tracers whereas alcohols С4–С5 approach for a role of partitioning tracers.monoatomic alcohols, system ”formation water–n-dodecane”, distribution constants, gas chromatography, tracers
