STABILIZATION OF SOLUTIONS OF ALIPHATIC PEROXYACIDS

The effect of small amounts of organic compounds on the stabilization of aliphatic peroxyacid solutions was investigated. The stabilizing effect of complexing agents depends on the metal ion of the catalyst and the reaction medium. In media containing water, Trilon-B is the most effective.The catalytic decomposition of peroxydecanoic acid in acetone proceeds at the lowest rate. The activation energies of the catalytic decomposition reaction have been found. The catalytic decomposition of PDA in toluene proceeds at a high rate, so this solvent is impractical to use. The effect of various complexing agents on the stabilization of acetone solutions of peracids was studied and it was shown that the best stabilizers are 8-oxyquinoline, α-picolinic acid and trilon-B. The effect of various complexing agents on the stabilization of acetone solutions was studied The effect of various complexing agents on the stabilization of acetone solutions of peracids was studied and it was shown that the best stabilizers are 8-oxyquinoline, α-picolinic acid and trilon-B. Effective stabilizers of peroxyacids form a strong compound with the metal ion of the catalyst, the catalytic activity of which is lower. Complexing agents are able to oxidize with peroxyacid molecules, which affects their stabilizing activity.

Keywords: peroxyacids, stabilization, decomposition constants, activation energies, catalytic decomposition.
