Low Temperature Pyrolysis

Some hydrogen phthalate esters of tertiary alcohols have been subjected to liquid phase pyrolysis. Olefinic mixtures and phthalic acid are the only products of the reaction. A study of the olefin distribution for each of the compounds pyrolyzed was made. Evidence of ionic character in liquid phase pyrolysis is presented.

The hydrogen phthalate ester of trans-l,2-dimethylcyclohexanol was prepared by using phthalic anhydride enriched in 18O. The ester was partially decomposed at 128°. An observed enrichment of 18O in the alcohol portion of the undecomposed ester supports an earlier postulate that an ion pair is involved in the thermal decomposition of this sterically hindered ester.

Fluorescent Screen

In this form of electron microscopy, photoelectrons emitted from a metal by ultraviolet radiation are accelerated and imaged onto a fluorescent screen by conventional electron optics. image contrast is determined by spatial variations in the intensity of the photoemission. The dominant source of contrast is due to changes in the photoelectric work function, between surfaces of different crystalline orientation, or different chemical composition. Topographical variations produce a relatively weak contrast due to shadowing and edge effects.Since the photoelectrons originate from the surface layers (e.g. ∼5-10 nm for metals), photoelectron microscopy is surface sensitive. Thus to see the microstructure of a metal the thin layer (∼3 nm) of surface oxide must be removed, either by ion bombardment or by thermal decomposition in the vacuum of the microscope.
