SYNTHESIS AND REACTION KINETICS OF A Mg-Fe-Mn …

Glycine was synthesized with high yield (>98 %) from ammonia and monochloroacetic acid in the presence of hexamethylenetetramine in an aqueous solution. Hexamethylenetetramine accelerates the reaction between monochloroacetic acid and ammonia, the undesirable side-reactions, such as formation of iminodiacetic acid are suppressed, thus glycine can be obtained with high yield. On the basis of detailed kinetic investigations the apparent rate constants and the reaction mechanism are also described.

A kinetic model for the DPC synthesis reaction was proposed and kinetic parameters for the proposed model was determined from batch reactor experiments.

Combes quinoline synthesis - Wikipedia

Diphenyl(diphenylethynyl)silane ((ph–C≡C)2–Si–ph2) (DPDPES) was synthesized by the Grignard reaction. The corresponding isothermal and non-isothermal cure kinetics of DPDPES were analyzed by using differential scanning calorimetry (DSC), and the molecular structure was characterized by H-NMR. The results showed that all the cure curves were typically sigmoid shape and cure reactions could be described by an autocatalytic kinetic model by isothermal DSC. The kinetic data, for example, activation energy (E) and frequency factor (A), were 119.22 kJ/mol and 4.67 × 107 (s−1), respectively. The non-isothermal DSC analyses showed that E and A were 162.12 kJ/mol and 1.32 × 109 (s−1), respectively, and the reaction order was 0.94. Based on the research work of this paper, it can be said that the cure reaction of DPDPES monomer was of autocatalytic and diffusion-controlled characteristics, and the effect of the diffusion was more evident at low temperature. The cure reaction of DPDPES was a first-order kinetic reaction.
