Design and Control of Glycerol-tert-Butyl Alcohol Etherification Process
Design, economics, and plantwide control of a glycerol-tert-butyl alcohol (TBA) etherification plant are presented. The reaction takes place in liquid phase, in a plug flow reactor, using Amberlyst 15 as a catalyst. The products' separation is achieved by two distillation columns where high-purity ethers are obtained and a section involving extractive distillation with 1,4-butanediol as solvent...
متن کاملReactive Distillation - a Viable Solution for Etherification of Glycerol with tert-Butyl Alcohol
Two different alternatives for etherification of glycerol (G) with tert-butyl alcohol (TBA) are developed and analyzed. The conventional reaction separation recycle system uses a plug-flow reactor to perform the reaction in liquid phase, in the presence of a heterogeneous catalyst (Amberlyst 15). The separation of the products from reactants is achieved by two distillation columns where pure gl...
متن کاملSulfonated porous carbon catalyzed esterification of free fatty acids
The esterification of free fatty acids (FFA) with methanol is studied using Sulfonated Porous Carbon (SPC) as catalyst. In compare to the amorphous sugar catalyst and protonated Nafion, the proposed catalyst shows stability and high efficient performance in biodiesel production. The highest initial rate of oleic acid conversion is obtained at catalyst loading of 1 mmol H+ and mole ra...

متن کاملIodine-catalyzed etherification of morroniside.
In this study, we describe a highly selective etherification procedure of unprotected morroniside catalyzed by molecular iodine in acetone. The etherification reaction furnished 7-O-alkyl ether derivatives in reasonable yields within few hours under neutral conditions. Studies of the obtained products on cytotoxicity activity in colon 26-L5 cell line were examined. Among the tested compounds, 7...
