Volume mixing ratios of each species are based on the works of Madhusudhan et al. (2014), Bitsch & Battistini (2020), and Schneider & Bitsch (2021a,b), and their condensation temperatures are from Lodders (2003). We adapted the standard implementation of chemcomp to follow C₂H₂ and refractory organics instead of NH₃ and C. The sub-limation temperature of C₂H₂ is taken from Penteado et al. (2017), while the value for refractory species is taken from Nakano et al. (2003) for refractory organics. Moreover, we did not consider the evolution of Fe₃O₄. Solar elemental abundances (Asplund et al. 2009) are assumed.
