Jung, Joori; Shin, Byeong Soo; Kang, Jeong Won; Han, Won-Sik published their research in Catalysts in 2021. The article was titled ãCatalytic Hydrogenation and Dehydrogenation Reactions of N-alkyl-bis(carbazole)-Based Hydrogen Storage Materialsã?Formula: C8H14O4 The article contains the following contents:
Recently, there have been numerous efforts to develop hydrogen-rich organic materials because hydrogen energy is emerging as a renewable energy source. In this regard, we designed and prepared four new materials based on N-alkyl-bis(carbazole), 9,9â?(2-methylpropane-1,3-diyl)bis(9Hcarbazole) (MBC), 9,9â?(2-ethylpropane-1,3-diyl)bis(9H-carbazole) (EBC), 9,9â?(2-propylpropane-1,3- diyl)bis(9H-carbazole) (PBC), and 9,9â?(2-butylpropane-1,3-diyl)bis(9H-carbazole) (BBC), to investigate their hydrogen adsorption/hydrogen desorption reactivity depending on the length of the alkyl chain. The gravimetric densities of MBC, EBC, PBC, and BBC were 5.86, 5.76, 5.49, and 5.31 H2 wt%, resp., again depending on the alkyl chain length. All materials showed complete hydrogenation reactions under ruthenium on an alumina catalyst at 190 °C, and complete reverse reactions and dehydrogenation reactions were observed under palladium on an alumina catalyst at <280 °C. At this temperature, all the prepared compounds were thermally stable, and no decomposition was observed After reading the article, we found that the author used Diethyl 2-methylmalonate(cas: 609-08-5Formula: C8H14O4)
Diethyl 2-methylmalonate(cas: 609-08-5) belongs to aliphatic hydrocarbons. Aliphatic hydrocarbons belong to the most abundant fraction in crude oil. Aliphatics molecules are linear or branched open-chain structures such as n-alkanes, isoalkanes, cycloalkanes (naphthenes), terpenes and steranes.Formula: C8H14O4
