Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 4-(Hydroxymethyl)-1,3-dioxolan-2-one, is researched, Molecular C4H6O4, CAS is 931-40-8, about A selective synthesis of glycerol carbonate from glycerol and urea over Sn(OH)2: a solid and recyclable in situ generated catalyst.Recommanded Product: 931-40-8.
In this work, we report a selective and straightforward process to synthesize glycerol carbonate from urea and glycerol using a simple but com. unavailable catalyst (Sn(OH)2). This catalyst was generated in situ from the reaction of Sn(II) halides and urea during the glycerol carbonatation process. Effects of main reaction parameters (i.e., temperature, molar ratio of urea to glycerol, catalyst concentration) were investigated. Different tin halides were assessed as catalytic precursors, with SnCl2 being the most efficient. We found that Sn(OH)2-catalyzed glycerol carbonation reactions with urea achieved high conversion and selectivity (ca. 87 and 85%, resp.). The samples of Sn(OH)2 generated in situ or previously synthesized were equally active and selective catalysts toward glycerol carbonate were successfully reutilized without loss activity. This is a very attractive route based on two inexpensive and readily available feedstocks in a chem. cycle that, overall, results in the chem. fixation of carbon dioxide and, concomitantly, adds value to glycerol, a biodiesel byproduct.
