Studies related to the chemistry and environmental persistence of methoxychlor and its derivatives / by James Paul Vukmanich. --
An Investigation of some of the chemical and biological factors Influencing the environmental fate of methoxychlor ( 1 , 1, 1-trichloro-2,2-bis (p-methoxyphenyl) ethane) has been conducted. Methoxychlor is an organochlorine ...
Photolysis of poly-acyl styrene polymers / by Kenneth G. Whiting.
The following is a study of the long wave (wavelength >300 nm) photolysis of a series of poly acyl styrenes, in particular, poly-p-acetyl-styrene (PPAS), polyp- propionyl-styrene (PPPS), poly-o-acetyl-styrene (POAS), ...
Reactions of Ni(II) with NaBh4 and NaBh3 CN in the presence of mono-and bidentate phosphines under CO atmosphere / by Hameed A. Mirza
Phosphine-substituted carbonyl complexes of Ni have been prepared. The reaction between NiC12.6H20, NaBH4 or NaBH3CN and either PPh3 or a series of phosphines of the type Ph2P-(CH2)n-PPh2 (n=1-5) and also cis-dppe under ...
Dielectric relaxation and infrared studies of hydrogen bonding / Mohammed Arshad Siddiqui. --
Dielectric relaxation and infrared study of a number of associating (H-bonding) compounds in glassy media, mainly polystyrene, have been carried out. The dielectric measurements by a General Radio 1621 Precision ...
Dielectric studies of molecular motions in some solids / by Md. Sohrab Hossain. --
Dielectric absorption of a number of nonpolar, weakly polar and fairly polar molecules in the pure solid state are studied. Measurements of these solids using either a General Radio 1621 Precision Capacitance Measurement ...
