Abstract:

Ozonolysis of alkenes is extremely important in the troposphere. Criegee intermediates (CIs) are the key intermediates in the ozonolysis of alkenes. The reactions of CIs are important sources of atmospheric OH radicals, organic acids, sulfuric acid, and nitrate etc, thus CIs receive much attention. There are seldom CIs detection methods due to CIs’ short-life time. Currently, how to detect CIs is a quite hot issue. The research progress of CIs measure including a variety of detection methods and their characteristics in recent years is summarized. These methods are briefly divided into direct and indirect detection methods. Finally, these methods are compared and the directions for future research are prospected.

Key words: spectroscopy, detection, criegee intermediates, ozonolysis
