This disclosure relates to a highly efficient and safe reactor for the continuous quenching of peroxide mixtures generated during the reaction of unsaturated compounds with ozone, which minimizes the amount of highly reactive peroxides accumulated in the reactor at any given time. The reactor may be modified to allow for expansion to accommodate the quenching parameters of a wide variety of ozonolysis reactions and flow rates. The reactor may be constructed from highly pressure rated stainless steel for maximum durability, safety, and economic practicality while increasing the safety of peroxide quenching, thus allowing tighter process control and improved product yields. This disclosure also related to methods for quenching ozonides.

A preparation method of carboxylic acids or ketones using ozone, singlet state oxygen atom O(.sup.1D) or hydroxyl free radical is provided. The method includes: filling ozone, singlet state oxygen atom O(.sup.1D) and/or hydroxyl free radical to cycloalkanes or benzenes at a pre-determined temperature and a pre-determined pressure in the presence or absence of light irradiation to produce carboxylic acids or ketones. The reaction occurs at room temperature and atmospheric pressure without producing harmful side products. The preparation method is a simple, low energy consuming, and eco-friendly method.
