“…Therefore, the above results demonstrate that it is hard to get a complete reaction because of the chemical equilibrium and a plateau is usually observed under various reaction conditions. This phenomenon is in good agreement with those reported in literatures [18,19]. The optimal reaction parameters thus can be set as: temperature of 130°C, reaction time of 2 h, DMC to glycerol molar ratio of 2:1, and catalyst loading of 3 wt.%.…”

“…Later, Choi et al [12] and Bolívar-Diaz [13] obtained glycidol through glycerol carbonate using [BMIm]-based ionic liquids and metallic oxide modified ZSM-5 zeolite as catalysts, respectively. Despite the excellent yields and selectivities, there has been little attention paid to the one-pot synthesis of glycidol directly from glycerol and DMC [17][18][19][20]. Kelkar et al [17] reported their pioneering work on the one-pot synthesis of glycidol using tetramethylammonium hydroxide as catalyst.…”

Given the large amount of anthropogenic CO2 emissions, it is advantageous to use CO2 as feedstock for the fabrication of everyday products, such as fuels and materials. An attractive way to use CO2 in the synthesis of polymers is by the formation of five‐membered cyclic organic carbonate monomers (5CCs). The sustainability of this synthetic approach is increased by using scaffolds prepared from renewable resources. Indeed, recent years have seen the rise of various types of carbonate syntheses and applications. 5CC monomers are often polymerized with diamines to yield polyhydroxyurethanes (PHU). Foams are developed from this type of polymers; moreover, the additional hydroxyl groups in PHU, absent in classical polyurethanes, lead to coatings with excellent adhesive properties. Furthermore, carbonate groups in polymers offer the possibility of post‐functionalization, such as curing reactions under mild conditions. Finally, the polarity of carbonate groups is remarkably high, so polymers with carbonates side‐chains can be used as polymer electrolytes in batteries or as conductive membranes. The target of this Review is to highlight the multiple opportunities offered by polymers prepared from and/or containing 5CCs. Firstly, the preparation of several classes of 5CCs is discussed with special focus on the sustainability of the synthetic routes. Thereafter, specific classes of polymers are discussed for which the use and/or presence of carbonate moieties is crucial to impart the targeted properties (foams, adhesives, polymers for energy applications, and other functional materials).

The adsorption of Basic Red 18 (BR 18) from aqueous solution onto KF modified sepiolite was carried out as a function of pH, initial dye concentration, contact time and temperature. The equilibrium data were evaluated according to Langmuir and Freundlich models. The experimental results showed that the best correlation was obtained on Freundlich model. The adsorption kinetics was examined with pseudo-first order, pseudo-second order and intraparticle diffusion models. The result was best fitted for pseudo-second order kinetic model. Thermodynamic investigations were also performed to determine ΔH°, ΔG° and ΔS°. The results indicated that the adsorption of BR 18 was exothermic and spontaneous.
