“…Meanwhile, the reaction rate increased with the catalyst concentration increasing and got to a fixed value when the catalyst concentration began up to 1.15 mol %. This phenomenon is in agreement with many literatures 16,17 and could be attributed to the reason that the reaction began to be controlled mainly by the mass transfer limitations and no longer the reaction kinetics, which can be enhanced by increasing catalyst concentration or temperature. The initial rate of reaction r 0 (mol mol −1 h −1 ), which is defined as the initial consumption rate of phenol, can be obtained by differentiation of the phenol mole fraction in the liquid system.…”

The kinetic behavior of preparing diphenyl carbonate by the transesterification of dimethyl carbonate with phenol in a reactive distillation reactor has been explored experimentally and theoretically. The transesterification reaction was described to conform a pseudo-second-order kinetics, and a semi-empirical kinetic model has been derived to explain the kinetic behavior. The model parameters were fitted to experimental data by an improved genetic algorithm. The proposed model was determined to be useful in simulating the rate constant and the mole fraction of components, which agreed well with the experimental data for different operating temperatures and catalyst concentrations.

“…For the synthesis of DPC from the transesterification between DMC and phenol, a variety of homogeneous catalysts have firstly been reported [19][20][21][22][23], especially the organic tin or titanium compounds. Although the homogenous catalysts reported in the references have high activity for the direct synthesis of DPC, the separation of the catalysts from the products will be complicated Scheme 1. when these catalyst systems are applied to the industrial process.…”

“…Among linear carbonates the most important are dimethylcarbonate (DMC), diphenylcarbonate (DPC) and diethylcarbonate (DEC). DMC is used in the chemical industry as monomer for polymers, in transesterification reactions for the production of other carbonates such as diphenylcarbonate and others, as alkylating or carboxylating agent . It is also used in the agrochemical and pharmaceutical industry for the production of chemicals or in product formulation.…”

CO2 is considered to play a key role in an eventual climate change, due to its accumulation in the atmosphere. The control of its emission represents a challenging task that requires new ideas and new technologies. The use of perennial energy sources and renewable fuels instead of fossil fuels and the conversion of CO2 into useful products are receiving increased attention. The utilization of CO2 as a raw material for the synthesis of chemicals and fuels is an area in which scientists and industrialists are much involved: the implementation of such technology on a large scale would allow a change from a linear use of fossil carbon to its cyclic use, mimicking Nature. In this paper the use of CO2 as building block is discussed. CO2 can replace toxic species such as phosgene in low energy processes, or can be used as source of carbon for the synthesis of energy products. The reactions with dihydrogen, alcohols, epoxides, amines, olefins, dienes, and other unsaturated hydrocarbons are discussed, under various reaction conditions, using metal systems or enzymes as catalysts. The formation of products such as formic acid and its esters, formamides, methanol, dimethyl carbonate, alkylene carbonates, carbamic acid esters, lactones, carboxylic acids, and polycarbonates, is described. The factors that have limited so far the conversion of large volumes of CO2 are analyzed and options for large‐scale CO2 catalytic conversion into chemicals and fuels are discussed. Both homogeneous and heterogeneous catalysts are considered and the pros and cons of their use highlighted. © 2013 Society of Chemical Industry
