The gas-phase reaction networks are the backbone of astrochemical models.
However, due to their complexity and non-linear impact on the astrochemical
modeling, they can be the first source of error in the simulations if incorrect
reactions are present. Over time, following the increasing number of species
detected, astrochemists have added new reactions, based on laboratory
experiments and quantum mechanics (QM) computations as well as reactions
inferred by chemical intuition and similarity principle. However, sometimes no
verification of their feasibility in the interstellar conditions, namely their
exothermicity, was performed. In this work, we present a new gas-phase reaction
network, GRETOBAPE, based on the KIDA2014 network and updated with several
reactions, cleaned from endothermic reactions not explicitly recognized as
such. To this end, we characterized all the species in the GRETOBAPE network
with accurate QM calculations. We found that 5% of the reactions in the
original network are endothermic although most of them are reported as
barrierless. The reaction network of Si-bearing species is the most impacted by
the endothermicity cleaning process. We also produced a cleaned reduced
network, GRETOBAPE-red, to be used to simulate astrochemical situations where
only C-, O-, N- and S- bearing species with less than 6 atoms are needed.
Finally, the new GRETOBAPE network, its reduced version, as well as the
database with all the molecular properties are made publicly available. The
species properties database can be used in the future to test the feasibility
of possibly new reactions.Comment: ApJS submitte
