Recent Study of Fluorine Compounds

Thermochemistry of Organic Fluorine Compounds and Carbon Compounds

Rotating-bomb calorimetry was first applied to organic compounds that contain chlorine, bromine, or sulphur. Techniques developed for these classes of compounds, mostly at the University of Lund and at the Bureau of Mines in Bartlesville, have been described in the book Experimental Thermochemistry-, The development of rotating-bomb methods made accurate combustion calorimetry feasible for othe...

Determination of fluorine in organic compounds.

[Health effects of fluorine and its compounds].

Fluoride, the ionic form of fluorine, is a natural component of the biosphere and 13th most abundant element in the crust of the earth. It is, therefore, found in a wide range of concentrations in virtually all inanimate and living things. Many trace elements perform a definite function in human metabolism and the question of the value of fluoride, always found in the body, has been raised. Muc...

Recent Methodology Developments in Soil Fluorine Analysis

Introduction Fluorine (F) is one of several trace elements receiving much attention owing to its possible harmful effects on health and environment. There are many methods used as the standard method of analysis of total F in soil. These include: ion selective electrode (ISE); X–ray fluorescence (XRF); Ion chromatography; Instrumental Neutron Activation Analysis (INAA); and Atomic and molecular...

Recent Investigations of Psychotropic Compounds

tetrachloride in T H F produces blue-green crystals that are stable to water and to aqueous acid or alkali. The compound can be sublimed or recrystallized from benzene or toluene. The compound is pyrophoric but controlled air oxidation yields uranium oxides and cyclooctatetraene. Mass spectral analysis gives a parent peak for U(CeH& and the fragmentation pattern indicates a ferrocene-like sandw...
