The composition and distribution features of unique structures in > 20
0-degrees-C-boiling aromatic fractions have been studied in the East T
urkmen gas-condensates enriched in adamantane-like structures. The nat
ure and distribution of these structures is original. The highest comc
entrations of non-replaced structures belonging to the diphenyl, phena
nthrene, and dibenzthiophene series have been found in the most adaman
tane-rich fluids.
