National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Abstract	The etherification isoamylenes 2-methyl-1-butene (2M1B) and 2-methyl-2-butene (2M2B) with ethanol was studied in liquid phase using a strong cation exchange resin as catalyst in a plug flow reactor. The conversion of the isoamylenes with ethanol to 2-ethoxy-methylbutanes (TAEE) was appreciably lower than that with methanol to 2-methoxy-2-methylbutane (TAME). Above 333 K the etherification was limited by the theromodynamic equilibrium. The reaction equilibrium constants for the liquid phase formation of TAME and TAEE were determined experimentally in the temperature range 323-363 K. The experimental equilibrium constants are presented as a function of temperature. At 333 K the constants for the formation of TAME were 39.6 (2M1B) and 4.1 (2M2B) and those for TAEE 17.4 (2M1B) and 1.7 (2M2B). The experimental enthalpy changes for the formation of TAME were -33.6 kJ/mol (2M1B) and -26.8 kJ/mol (2M2B), and those for the formation of TAEE -35.2 kJ/mol (2M1B) and -27.3 kJ/mol (2M2B).
