Perception of glycerol carbonate as green chemical: Synthesis and applications

Catalysis Communications, 2022
Glycerol carbonate (GC) is a prominent component in industrial practice and has a remarkable potential for the sophisticated applications. While GC has come into prominence due to the perceived overflow of glycerol (GLY) as a coproduct of biodiesel ...

Enhanced conversion of Glycerol to Glycerol carbonate on modified Bio-Char from reed plant

Iraqi Journal of Chemical and Petroleum Engineering, 2019
The surplus glycerol produced from biodiesel production process as a by-product with high quantity can be considered as a good source to prepare glycerol carbonate (GC) whereas with each 1000 kg from biodiesel obtains 100 kg from glycerol.

Dielectric and thermal relaxation in the energy landscape [PDF]

, 2006
We derive an energy landscape interpretation of dielectric relaxation times in undercooled liquids, comparing it to the traditional Debye and Gemant-DiMarzio-Bishop pictures. The interaction between different local structural rearrangements in the energy

Li掺杂CeO2固体碱催化甘油酯交换合成碳酸甘油酯

Zhongguo youzhi, 2023
针对由甘油制备碳酸甘油酯的酯交换法中催化剂制备方法复杂、活性组分易流失等问题，采用一锅法制备了Li掺杂CeO2固体碱催化剂。对催化剂进行了X射线衍射(XRD)、扫描电镜（SEM）、透射电镜（TEM）、BET、X射线光电子能谱(XPS)、CO2程序升温脱附(CO2-TPD)等表征。以甘油转化率和碳酸甘油酯产率为指标，对催化剂进行了筛选，并采用单因素实验对甘油酯交换合成碳酸甘油酯的工艺条件进行了优化，同时考察了催化剂的重复使用性能。结果表明:Li与CeO2之间能够产生协同作用 ...
