Abstract

The reaction of nitrous oxide with internal olefins is investigated in a flow reactor. When using a mixture of dodecene isomers, ketones are formed es the primary-product with conversions up to 77% and yields up to 45%. The multiphase system is studied experimentally and computationally to gain understanding of the residence time distribution and Phase composition. Significant volatility of the dodecenes and solubility of the nitrous Oxide result hi a system where reaction occurs in both the vapor and liquid at elevated temperatures: The rate constant for oxidation with nitrous oxide is deterinined by considering both phases and the material transfer between them using 16 different physical parameters through nonlinear optimization. The determined rate constant is in good agreement with parameters estimated by quantum chemistry calculations.
