First claim
Opening claim text (preview).
We claim: 1. A method for making a peroxycarboxylic acid, comprising: providing a liquid composition of a carboxylic acid and an oxidizing agent; pretreating the liquid composition with a pretreatment column to remove metal ion from the mixed composition, wherein the pretreatment column comprises a removable cartridge; measuring a condition of the liquid composition, wherein the condition comprises pressure i) before pretreating and ii) at site of pretreating during pretreatin…
