Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 18742-02-4, Name is 2-(2-Bromoethyl)-1,3-dioxolane. In a document, author is Raso, R., introducing its new discovery. Formula: C5H9BrO2.
Aqueous phase hydrogenolysis of glycerol over Ni/Al-Fe catalysts without external hydrogen addition
The present work studied the aqueous phase hydrogenolysis (APH) of glycerol (a by-product of biodiesel manufacturing) without external hydrogen addition to produce value-added products. A series of catalysts based on 28 molar % of Ni were prepared through co-precipitation by changing the Al/Fe molar ratio. The calcined and used catalysts were characterized by several techniques (ICP-OES, N-2-physisorption, XRD, H-2-TPR, NH3-TPD, FESEM and STEM). This work examines the effects of the molar ratio of Al/Fe on the physicochemical characteristics of Ni/Al-Fe catalysts and during the APH of glycerol. All the catalysts showed low carbon yields to gases and high carbon yields to liquid products, mainly 1,2-propanediol, acetol and ethylene glycol. Ni/Al3Fe1 catalyst gave the best performance in the APH of glycerol: the highest glycerol conversion (42.31 %), carbon yield to gases (6.57 %) and carbon yield to liquids (30.45%). 1,2-propanediol was the liquid product with the highest carbon selectivity (70.89%).
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 18742-02-4 help many people in the next few years. Formula: C5H9BrO2.
