Abstract

Temperature-programmed desorption mass spectrometry was used to study the reaction of a series of primary amines (isobutylamine, isopentylamine, 1-pentylamine, 1-hexylamine, and 1-heptylamine) with a fumed silica surface. A mechanism was proposed and the kinetic parameters of the formation of alkenes from the chemisorbed aliphatic amine fragments on the silica surface were determined. A linear correlation was found between the activation energy and Taft constants for the substituents at the reaction site.
