Co-Production of Dimethyl Carbonate, Dimethoxymethane and Dimethyl Ether from Methanol: Process Design and Exergy Analysis.

Dimethyl carbonate is an important green chemical that has been widely used in the chemical industry. In the production of dimethyl carbonate, methanol oxidative carbonylation has been studied, but the conversion ratio of dimethyl carbonate using this method is too low, and the subsequent separation requires a large amount of energy due to methanol and dimethyl carbonate being azeotrope. In this paper, the strategy of "reaction instead of separation" is proposed.

Theoretical analysis and evaluation of reaction routes by "three-parameter difference".

How to choose a high-efficiency, green and inherent safety synthetic route is an important issue for the development of the chemical industry. "Three-parameter difference" is a complex parameter with the calculation of Gibbs free energy, atom utilization and inherent safety index, and can be used to comprehensively evaluate the thermodynamic feasibility, greenness and safety of chemical reactions. This parameter has been proposed and established, but the reliability has not been determined.

Preparation and catalytic performance of active metal sintered membrane reactor anchored with Pt atoms.

In the chemical industry, reactors are typically designed and filled with supported catalyst particles. However, the intrinsic problems associated with the internal/external diffusion effect and catalyst separation/loss in these traditional reactors can be very challenging to mitigate. To address these issues, herein, an active metal sintered membrane reactor anchored with Pt atoms was successfully developed, and applied into continuous, liquid-phase, hydrogenation processes.

The effect of adsorption and grafting on the acidity of [(HSO)C3C1im][Cl] on the surface of (SiO)OH clusters.

Both adsorption and graft of active components on the surface of the silica are paramount methods for preparing heterogeneous catalysts. In this paper, the acidity of [(HSO)C3C1im][Cl] adsorbed and grafted on the surface of silica clusters was calculated at the level of B3LYP-d3/6-311++g(d, p). The results showed that both methods can enhance the acidity of the ionic liquids (ILs).
