Research of distribution of C1–C5 aliphatic monoatomic alcohols in a system “formation water–n-dodecane”

The paper presents the experimental research of distribution of nine С1–С5 aliphatic monoatomic alcohols of normal and isomeric structure in a two-phased heterogenous system "formation water–n-dodecane using gas-chromatography method for the purpose of a choice of the most effective tracers for the characterization of filtrational streams and oil saturation when waterflooding. There were defined distribution constants $K_c$ in interval of temperatures 25–75$^\circ$С 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.
