Revealing the role of stabilizers in H2O2 for the peroxyformic acid synthesis and decomposition kinetics

Epoxidation of Vegetable Oils via the Prilezhaev Reaction Method: A Review of the Transition from Batch to Continuous Processes

“…However, it is not straightforward to give a rigorous range as the reported numerical values of the activation energies depend on the kinetic approach adopted. Starting from the percarboxylic acid formation and decomposition, and considering formic acid first, the activation energy ranges between 20–75 and 73–105 kJ/mol, respectively. ,,,, For acetic acid, the activation energy ranges are 15–60 and 58–95 kJ/mol, respectively. − These values have been obtained in independent studies concerning the percarboxylic acid formation and decomposition in either autocatalytic mode or catalyzed experiments with either homogeneous or heterogeneous catalysts. Concerning the epoxidation and the ring-opening reactions, the activation energy ranges are between 25–50 and 55–104 kJ/mol, respectively. ,,,,, …”

“…103,110 Recently, in an article our group reported a correlation between the stabilizers present in the hydrogen peroxide solution and the thermal decomposition rate, by studying the performic acid formation and decomposition kinetics. 108 Thus, this aspect might be considered in the rate equation (eq 3.2).…”

“…Starting from the percarboxylic acid formation and decomposition, and considering formic acid first, the activation energy ranges between 20−75 and 73−105 kJ/mol, respectively. 108,109,111,162,175 For acetic acid, the activation energy ranges are 15−60 and 58−95 kJ/mol, respectively. 176−178 These values have been obtained in independent studies concerning the percarboxylic acid formation and decomposition in either autocatalytic mode or catalyzed experiments with either homogeneous or heterogeneous catalysts.…”

“…The results suggested that the longer the alkyl chain, the less reactive is the corresponding percarboxylic acid in the epoxidation process (formic > acetic > propionic acid). However, the longer the alkyl chain, the more stable thermally is the percarboxylic acid. , Recently, in an article our group reported a correlation between the stabilizers present in the hydrogen peroxide solution and the thermal decomposition rate, by studying the performic acid formation and decomposition kinetics . Thus, this aspect might be considered in the rate equation (eq ).…”

Determination of the Mass Transfer Parameters and Partition Coefficients for Formic Acid/Water/Soybean Oil System

“…Commonly, either acetic acid is used as a carboxylic acid. In the present paper, formic acid will be used, as the shorter the alkyl chain the faster is the percarboxylic acid formation, , thus leading to a shortening of the reaction times. In this scenario, the mass transfer from one phase to the other for both the carboxylic acid and its corresponding peracid might play a crucial role in the epoxidation process, and its impact is affected by the mass transfer coefficient and the phase equilibrium.…”
