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 method for synthesizing 4-(Hydroxymethyl)benzoic acid using P-xylene (PX) as a raw material, including: dissolving PX in an organic solvent to undergo an oxidation reaction with an oxidizing agent under an action of an M-MOF catalyst; and after the oxidation reaction, performing a post-treatment to obtain the 4-(Hydroxymethyl)benzoic acid; wherein, the metal element M in the M-MOF catalyst is Fe, Cu, Cr, Mn, Cu/Fe, Cu/Cr, Cu/Mn, Fe/Mn, Cr/Fe or Cr/Mn. The by-product produced in the reaction process is little, the yield is high, and the separation is convenient. The acid-base neutralization is not required in the reaction process, reducing pollution. A one-step reaction is employed which has mild reaction conditions, short reaction time, low pollution and is convenient for industrialized mass production; and the obtained 4-(Hydroxymethyl)benzoic acid can be used for preparing medicines and liquid crystal materials having wide applications.
