“…According to the Arrhenius law, a high temperature makes molecules move faster and collide more vigorously, and therefore greatly increased the likelihood of bond cleavages and rearrangements, but the excessive high reaction temperature was inadvisible due to the presence of a double bond in methyl acrylate and acrylic acid. Thus, the optimized reaction temperature for the transeatrification was 353.15 K through synthetic consideration. , …”

“…These reactions can be performed using base catalysts 7,8 such as metal hydroxides, metal alkoxides, alkaline-earth oxides, and hydrotalcites. Moreover, acid catalysts 9-14 such as sulfuric, sulfonic, phosphoric, and hydrochloric acids can also be used to catalyze the transesterification reaction.…”

“…Transesterification, which is an important chemical reaction in industry, includes three reaction types: alcoholysis, acidolysis, and ester exchange reaction. These reactions can be performed using base catalysts , such as metal hydroxides, metal alkoxides, alkaline-earth oxides, and hydrotalcites. Moreover, acid catalysts − such as sulfuric, sulfonic, phosphoric, and hydrochloric acids can also be used to catalyze the transesterification reaction.…”

Reaction distillation was firstly used for the process of acrylic acid synthesis through transesterification of methyl acrylate with acetic acid using a strongly acidic cationic exchange resin catalyst (NKC-9). Pseudo-Homogeneous (P-H) and Langmuir-Hinshelwood (L-H) heterogeneous kinetic models were presented and fitted with the experiment data obtained from batch reaction. The key factors of heterogeneous kinetic model were the four components adsorption equilibrium constants on the catalyst surface and they were determined by adsorption experiments. The activity coefficients were calculated using the NRTL method. The catalyst stability was evaluated in a fixed-bed reactor. Catalyst activity had no obviously decrease after 1000 hours running. A reactive distillation column for acrylic acid synthesis was proposed and designed with process simulation.

“…In these cases, the catalytically active species are uniformly dispersed on the surface of the porous support. In several instances, supported materials have been shown to exhibit improved catalytic performance compared with the free catalysts, as well as offering significant reductions in the effective cost of the active catalyst [3][4][5][6].…”

A series of solid acids such as ZrO 2 , 5% Mo(VI)/ZrO 2 , 10% Mo(VI)/ZrO 2 , 20% Mo(VI)/ZrO 2 and SO 4 2-/ZrO 2 were prepared. These solid acids were characterized by BET, NH 3 -TPD / nbutylamine back titration, powder-XRD, FT-IR spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and ICP-OES techniques. The catalytic performance of these solid acids was evaluated in the synthesis of novel aromatic esters by the assistance of microwave irradiation and the catalytic activity of these solid acids was compared with pTsOH. The results clearly indicated that the zirconia based solid acids are efficient green catalysts for esterification reactions, which gave maximum yield of ester in shorter reaction time and comparable to the catalytic activity of pTsOH Brönsted acid. Kinetic studies were carried out to calculate the temperature coefficients (1.66 and 1.56) and energy of activation (66.
