Insights into the nucleation mechanism of N2O bubble during the oxidation of alcohol-ketone oil by nitric acid in microreactors
The nucleation mechanism of N2O bubble during the oxidation of alcohol-ketone mixtures (K/A oil) by nitric acid in microreactors was investigated through modeling approach. A comprehensive mathematical model was developed, taking into account detailed reaction kinetics, Helmholtz free energy theory and gas-liquid mass transfer process, and subsequently implemented by self-programming. This model successfully calculated the critical bubble nucleation radius under homogeneous, heterogeneous, and quasi-classical nucleation assumptions, with validation against experimental results. Additionally, the evolution of bubble diameter along axial location under different flow velocities and temperatures was investigated through the established model. This work can provide valuable insights for designing continuous flow tubular reactors with effective control over bubble sizes.
