The principal salinity extrema and extremum surfaces of the
world ocean are described by the analysis and plotting of data from
885 hydrographic stations in the three major oceans, the Southern
Ocean, and the American Mediterranean Sea. The distributions of
salinity, temperature, depth, and density along the extremum surfaces,
plotted...
Polyhalogenated benzenes have been analyzed by standard electron capture
chemical ionization mass spectrometry (ECCI/MS), and electron monochromator mass
spectrometer (EM/MS) systems. The EM/MS experiments distinguished electronegative
compounds (especially isomers) by transient negative ions (TNIs) of the same mass but
differing energies and/or the formation of distinct TNIs of different masses...
The photohydrodebromination of brominated paracyclophanes was studied to
help elucidate the possible mechanistic pathways leading to product for
bromoarenes in general. Several brominated [2.2]paracyclophanes were studied to
determine the effect of substitution patterns on this reaction. [2.2]Paracyclophanes
were chosen for this study in order to investigate possible intramolecular excimer
formation...
Several experiments were undertaken to investigate the mechanism of
photodechlorination of pentachlorobenzene. The thermal methoxydechlorination
reaction of pentachlorobenzene was studied. In DMSO at 50 °C sodium
methoxide reacts smoothly with pentachlorobenzene to give three
tetrachloroanisole isomers. A second-order kinetic plot for this reaction is linear to
high precision, indicating that...
