Abstract

A sequence of two organic reactions involving gas-phase heterogeneous catalysis suitable for use as a laboratory experiment is outlined. In the first reaction, 2-propanol is converted to propene using alumina beads as the catalyst. The product gas is purified with a mini-cold trap. In the second reaction, propene is hydrogenated to propane using a palladium catalyst in nearly 100% yield. The experiment demonstrates continuous-flow, closed-system gas-phase reactions of fundamental importance in chemical industry. It also demonstrates the power of NMR in the context for which it actually is used by organic and inorganic chemists: structural confirmation and analysis.
