PROCESS FOR THE ACCELERATED PRODUCTION OF STABLE SOLUTIONS, IN E QUILIBRIUM, OF PERACETIC ACID IN LOW CONCENTRATIONS

摘要

The production of dilute equilibrium, storage stable solutions of peracetic acid from mixtures of aqueous hydrogen peroxide and acetic acid or by dilution of more concentrated peracetic and solutions takes a long time on account of the low concentrations of the active participating materials. The process can be accelerated by employing a two step procedure in which a concentrated peracetic acid solution is diluted with water and partially hydrolysed in the first step, and then the hydrolysis reaction is quenched by addition of hydrogen peroxide in the second step.
