Dynamic study of the synthesis of 1,1-dibutoxyethane in a fixed-bed adsorptive reactor. Separation Science Technolology. ISSN 0149-6395. 46, p. 631-6400149-6395http://hdl.handle.net/10198/5092The synthesis of 1,1-Dibutoxyethane in a fixed-bed adsorptive reactor using Amberlyst 15 was studied for the first time. The adsorption of non-reactive pairs was investigated experimentally, at 25 °C, by frontal chromatography in a fixed-bed adsorber. In order to avoid the immiscibility of the liquid phase, the liquid-liquid equilibrium for the mixture 1-butanol/water was studied. The multicomponent equilibrium adsorption data was assumed to follow the modified Langmuir type isotherm. Reaction experiments of 1,1-Dibutoxyethane production and column regeneration were performed in the fixed-bed adsorptive reactor. This work will enable further developments in chromatographic reactors aiming at the 1,1-Dibutoxyethane process intensification.eng1,1-DibutoxyethaneFixed-bed adsorptive reactorProcess intensificationjournal article10.1080/01496395.2010.5341211520-5754
