The kinetics of the synthesis of tert-Bu peroxy-2-ethylhexanoate were investigated in a capillary microreactor. TBPEH was synthesized from 2-ethylhexanoyl chloride and tert-Bu hydroperoxide in the presence of a strong base, using the Schotten-Baumann method. The peroxyesterification reaction is always in competition with the unwanted acid chloride hydrolysis. The synthesis was carried out with and without a phase-transfer catalyst. The non-catalyzed reaction showed a low rate, which could be incremented by increasing the temperature and the liquid-liquid interfacial area or by using KOH instead of NaOH as base. The peroxyesterification and hydrolysis rates increased with temperature However, the use of KOH or the increase in interfacial area accelerated only the peroxyester formation, increasing the selectivity towards the desired product. The addition of a PTC enhanced the peroxyesterification rate without changing the hydrolysis rate. Among the screened PTCs, quaternary ammonium salts with longer alkyl chains gave the best performance, up to 25 times faster peroxyesterification. The rate increase was proportional to the PTC amount The interfacial area had the same effect as in the non-catalyzed reaction. Because of the tremendous increase in the reaction speed due to the PTC, the rate increased with slug velocity. At low slug velocity the reactants in the thin liquid film surrounding the droplets in the capillary are depleted and the peroxyesterification rate decreases. A reaction mechanism is proposed that explains the exptl. observation. The corresponding kinetic model predicts the observed reaction rate with 10% accuracy.1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5Computed Properties of C10H20O5) was used in this study.
1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5) is a member of crown ether Ligands. Crown-ethers are macrocyclic polyethers capable of forming host-guest complexes, especially with inorganic and organic cations. Crown-ethers can incorporate protonated primary amine compounds by formation of ion-dipole bonds with the oxygen atoms of the chiral selector. Crown-ethers have been widely used for the separation of several pharmaceuticals both in aqueous and non-aqueous media. Computed Properties of C10H20O5
