The surface chemistry of benzene, acetylene, and ethylene adsorbed onto porous glass at approximately 120 K was studied under ultrahigh vacuum conditions using temperature programmed desorption, temperature programmed mass spectrometry and Fourier transform infrared spectroscopy. Preliminary data suggests that benzene and ethylene desorb intact, but that acetylene undergoes surface chemistry to produced adsorbed ethanol.
