Abstract

The diversity of organic molecules in our Solar System at present is a result of its chemical evolution in each stage from an interstellar molecular cloud to a solar nebula, asteroids, and planets. In this study, we investigated the formation efficiency of complex molecules from the abundant hydrogen and carbon monoxide molecules that are a part of the physical evolution of molecular clouds into the beginning of solar nebulae. We conducted a catalytic reaction experiment using realistic substrates, such as amorphous magnesium silicate and iron, at low temperatures (50-750 K) and low pressures (101 -103 Pa) in consideration of the actual environment. We found that the reaction efficiency depended on temperature and reached its highest point at 750 K, as expected. However, it was also found that the molecular evolution by catalytic reaction proceeded even at low temperatures in the range of 50-200 K.
