Synthesis of Dimethyl Carbonate from Urea and Methanol
There is a great concern on the utilisation of CO2 due to its increased atmospheric concentration by anthropological emissions in the last few decades. Therefore, the fixation of inexpensive and abundantly available CO2 in valuable chemicals is gaining lot of interest in recent times. Despite this, there are only a few industrial processes where CO2 is consumed directly. One such process is the...
متن کاملPreparation of Solid Superacid SO42-/ZnO-TiO2 and Its Action on Synthesis of Dimethyl Carbonate from Urea and Methanol
SO42-/ZnO-TiO2 catalyst was prepared by sulfating ZnO-TiO2 powders with H2SO4 solution. The catalyst was characterized by XRD, IR and Hammett indicator. The catalyst showed strong acidity(H0 ≦-16.0). The optimum conditions are found that the calcination temperature is 823K and the so...
متن کاملGas-Phase Synthesis of Dimethyl Carbonate from Methanol and Carbon Dioxide Over Co1.5pw12o40 Keggin-Type Heteropolyanion
The reactivity of Co(1.5)PW(12)O(40) in the direct synthesis of dimethyl carbonate (DMC) from CO(2) and CH(3)OH was investigated. The synthesized catalyst has been characterized by means of FTIR, XRD, TG, and DTA and tested in gas phase under atmospheric pressure. The effects of the reaction temperature, time on stream, and methanol weight hourly space velocity (MWHSV) on the conversion and DMC...
متن کاملSynthesis of propylene carbonate from urea and propylene glycol over zinc oxide: A homogeneous reaction
Abstract: In this work, several metal oxides and zinc salts were used to catalyze propylene carbonate (PC) synthesis from urea and propylene glycol (PG). According to the results of catalytic test and characterization, the catalytic pattern of ZnO was different from that of other metal oxides such as CaO, MgO and La2O3, but similar to that of zinc salts. In fact, the leaching of Zn species took...
متن کاملSynthesis of glycerol carbonate from glycerol and dimethyl carbonate in basic ionic liquids*
Glycerol carbonate is a key multifunctional compound used as solvent, additive, and building block in alternative chlorine-free processes. Here, we report the synthesis of glycerol carbonate from renewable materials (glycerol and dimethyl carbonate, DMC) using basic ionic liquids (ILs) as catalysts. After process optimization, it has been possible to isolate pure glycerol carbonate in quantitat...
