Heats of immersion and swelling of quaternary ammonium complexes of montmorillonites

Creator:: St. Clair, Akos Dominic
Abstract:: Heats of immersion were obtained for four different organophilic clay complexes in a series of normal alcohol-heptane mixtures with alcohols of increasing chain length. The immersion calorimeter employed was the Dewar type with a sensitivity of approximately 5 x 10⁻⁵°C. Gel volumes were determined for two of the clay complexes...

Low temperature thermal analysis of some boron halide complexes with weak Lewis bases

Creator:: Lerch, Ronald Edwin
Abstract:: Thermal analysis was used to investigate the following seven systems: H₂S-B₂F₄, SOF₂-B₂F₄, COC1₂-B₂F₄, SF₄-B₂F₄, Xe-BF₃, NF₃-BF₃, and NF₃-BC1₃. In two of the seven systems compound formation was observed. In the system, H₂S-B₂F₄ the compounds H₂S[superscript .]B₂F₄ and 2H₂S[superscript .]B₂F₄ are formed. The compound H₂S[superscript .]B₂F₄ has a melting point of...

Conformation and reactivity studies of some bicyclo(3.3.1) nonane derivatives

Creator:: Sturmer, David Michael
Abstract:: New syntheses for 2-bicyclo(3.3.1)nonanone and 7-bicyclo-(3.3.1)nonen-2-one were developed. The saturated ketone was prepared from phenol and acrylonitrile via a novel intramolecular S[subscript N]2 cyclization process. A Friedel-Crafts cyclization of 3-(3-cyclohexenyl)propanoyl chloride permitted synthesis of the unsaturated ketone from 4-cyclohexene carboxaldehyde. The formation of the bicyclo(3.3.1)nonane rather than a bicyclo(3.2.2)nonane skeleton...

Prediction and Measurement of Polycyclic Aromatic Hydrocarbons (PAHs) Transformation Products in the Environment.

Creator:: Titaley, Ivan A.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are a group of environmental contaminants consisting of fused benzene rings. Parent-PAHs, methylated-PAHs (MPAHs), and PAHs with molecular weight of 302 a.m.u (MW302-PAHs) are considered as unsubstituted-PAHs. These unsubstituted-PAHs undergo transformation reactions resulting in the formation of PAH-transformation products (PAH-TPs), or substituted-PAHs, including nitrated-, oxygenated-, and...
