Scientific paper

For a large set of temperatures, pressures and elemental compositions the chemical equilibrium abundances of 94 species including cyanopolyynes HC2ηCN for which new estimates of thermodynamical constants have been obtained are calculated. It is concluded that cyanopolyynes as well as the majority of other saturated molecules observed in the envelope of IRC +10216 are formed under chemical equilibrium conditions near the surface of the star. Their relative abundances "freeze out" due to rapid expansion and cooling of the envelope.
