Ethanol To Diethyl Ether Catalyst

Diethyl ether formed by the acid catalysed dehydration reaction of ethanol and sulfuric acid by the loss of water molecule sulfuric acid used as catalyst as well as a dehydrating agent 2 c 2 h 5 o h h 2 s o 4 c 2 h 5 o c 2 h 5 h 2 o.

Ethanol to diethyl ether catalyst. The proposed two step kinetic model highlights the mechanistically essential comparison between the strong brønsted and weak lewis acid sites of catalyst for ethanol conversion to diethyl ether. It could be nearly achieved the complete ethanol conversion at 400 c over al ssp composite catalysts. That weakness can be solved by the use of solid catalysts. No significant negative impact of water over diethyl ether yield was observed up to 1 1 ethanol water molar ratio.

Ethanol and diethyl ether temperature programmed surface reactions etoh tpsr and dee tpsr respectively were carried out with a bed constituted by 0 043 g of the catalyst mixed with 0 127 g of sand purchased from sigma aldrich and calcined at 1073 k for 6 h prior to use and using as reactant both ethanol 99 8 and dee 99 5. Ethanol conversion and ethylene selectivity increased when the reaction temperatures were raised whereas the diethyl ether decreased.
