Reaction Kinetics of Criegee Intermediates with Nitric Acid.

This work investigated the reaction kinetics of HNO with four Criegee intermediates (CIs): CHOO, (CH)COO, methyl vinyl ketone oxide (MVKO), and methacrolein oxide (MACRO). Our results show that these reactions are extremely fast with rate coefficients of (1.51 ± 0.

Substituent Effect in the Reactions between Criegee Intermediates and 3-Aminopropanol.

Via intramolecular H atom transfer, 3-aminopropanol is more reactive toward Criegee intermediates, in comparison with amines or alcohols. Here we accessed the substituent effect of Criegee intermediates in their reactions with 3-aminopropanol. Through real-time monitoring the concentrations of two Criegee intermediates with their strong UV absorption at 340 nm, the experimental rate coefficients at 298 K (100-300 Torr) were determined to be (1.
