Sustainable Process For The Production Of Symmetrical Dibasic Acid Ester-Based Thermal Energy Storage Materials From Lipids, Ayhan Yildirim, Kaan Kiraylar Jan 2019

Sustainable Process For The Production Of Symmetrical Dibasic Acid Ester-Based Thermal Energy Storage Materials From Lipids, Ayhan Yildirim, Kaan Kiraylar

Oleochemical-based long-chain diesters are potential organic phase change materials convenient for thermal energy storage. The development of efficient and green methods is an important requirement for the preparation of these environmentally friendly compounds, which also are finding wide industrial application. Thus, in the present work, a series of dibasic acid esters were synthesized through ionic liquid catalyzed scalable chemical esterification or transesterification reactions in a solvent-free medium. The starting compounds, dicarboxylic acids or their methyl esters and fatty alcohols or cholesterol, were reacted in the ratio of 1:2 respectively and the synthesized esters were characterized by FT-IR, $^{1}$H NMR, and …


Hydrogen Storage In Formic Acid As A Renewable Energy Source Using Heterogeneous Catalysis, Obaid Aldosari Jan 2019

Hydrogen Storage In Formic Acid As A Renewable Energy Source Using Heterogeneous Catalysis, Obaid Aldosari

Turkish Journal of Chemistry

One of the most vital chemicals, which is not only found naturally but can also be synthesized in the laboratory, is formic acid (FA). FA is a key byproduct of several second-generation biorefinery processes as well, and it is used in several pharmaceutical and industrial applications. Recently, another significant use of FA that is taking the lead is as a form of fuel. This could either involve reformation, as a possible form of chemical hydrogen storage, or be done without reformation in the form of FA fuel cells, in particular because FA fuel cells are much more effective than other …
