“…Meanwhile, this POM–IL [BMIm] 4 [Ti(H 2 O)TiMo 11 O 39 ] behaved as a phase transfer catalyst for the transesterification reaction between dimethyl carbonate and phenol to synthesize diphenyl carbonate. 84 Under optimized conditions, the phenol conversion reached 46%, and the overall selectivity of mono- and di-phenyl carbonate products was 99%. Moreover, the catalyst could be reused four to five times due to its characteristic of a “homogeneous phase at high temperature and separation at low temperature”.…”

“…Amino and carboxyl groups with strong acidity/alkalinity catalyzed decarboxylation side reactions to produce anisole, while methyl groups with weak acidity, although exhibiting good DPC selectivity, had lower conversions. Guo et al [90] developed polyoxometalate ionic liquids for transesterification, among which Bmim 4 [Ti(H 2 O)TiMo 11 O 39 ] (Bmim = 1-butyl-3-methylimidazolium cation) exhibited the best catalytic performance. With a molar ratio of DMC to phenol of 2:1, a reaction temperature of 180 • C, a catalyst dosage accounting for 1.5% of the total mass of raw materials, and a reaction time of 8 h, the conversion of phenol reached 46.17%, and the total selectivity of the products MPC and DPC was 98.89%.…”

Diphenyl carbonate is one of the raw materials used for the synthesis of polycarbonate, and its green and clean production is of great importance to the non-phosgene process for polycarbonate. The production of diphenyl carbonate by transesterification is its representative process route and is considered to be one of the typical examples of a green and sustainable process for chemicals. Since the discovery of the transesterification catalyst for diphenyl carbonate in the 1970s, researchers have been committed to improving its catalytic activity and selectivity and, correspondingly, the reaction engineering process. However, thermodynamic limitations, low activity, low selectivity, and limited stability have been bottlenecks that the transesterification catalyst has not been able to completely overcome, and the improvement of the catalyst is still ongoing. Therefore, this review takes the transesterification reaction of dimethyl carbonate and phenol as a model reaction and, based on a review of the progress in catalyst research on catalytic reaction processes, tries to clarify the structure–activity relationship between catalytic active sites and catalytic performance in homogeneous and heterogeneous catalytic processes and provides an overview of the progress in catalyst synthesis and modification.

“…38,41 Monosubstituted Keggin-type polyoxometalates-ionic liquid catalyst (POM-ILs) with high structural designability, excellent thermal stability, and higher reaction selectivity can be prepared by further combining green and clean ionic liquids with TMSPs. 34,39,[42][43][44] Jiang et al 44 prepared a series of POM-IL catalysts to catalyze the transesterification of phenol with dimethyl carbonate to prepare diphenyl carbonate. These findings demonstrate that the catalytic performance of the Bmim 4 [Ti(H 2 O)-TiMo 11 O 39 ] catalyst was higher, the phenol conversion rate reached 46.17%, and the total product selectivity reached 98.89%.…”

“…This series of catalysts demonstrated excellent catalytic performance for transesterification. In this research, a series of POM-IL catalysts were prepared 20,22,40,[42][43][44] and employed to catalyze the coupling reaction of EC with DMSu for the synthesis of PES, offering a crucial theoretical basis and process parameters for further enhancing the industrial production of PES synthesized by used EC. The schematic diagram of the synthetic route to PES is demonstrated in Fig.…”
