Claim:
1. A method for making a peroxycarboxylic acid, comprising: providing a liquid composition of a short chain carboxylic acid reagent, providing a liquid composition of a medium chain carboxylic acid reagent, and providing a liquid composition of an oxidizing agent reagent; pretreating the liquid compositions with a pretreatment column to remove metal ion from the liquid compositions before mixing the liquid compositions to form a mixed composition; measuring a condition of a liquid composition i) before pretreating and ii) at site of pretreating during pretreating; determining a difference between i) and ii); providing a detectable signal if the difference meets or exceeds a predetermined value; reacting the pretreated composition in the presence of a reaction catalyst that can be physically removed from reaction mixture to produce a peroxycarboxylic acid composition; and recovering the peroxycarboxylic acid composition.
