PHYSICAL PROPERTIES OF SURFACTANT ENHANCED MIXED SOLVENT SYSTEMS

Autor: Frederick R. Longo, Ngai M. Wong, Joseph W. Hovanec

Publikováno v: Journal of Dispersion Science and Technology. 16:543-555

The object of this research is to discover substitutes for halogenated solvents In detergent formulations. Recent work in our Laboratories indicates that the study of surfactant enhanced solvent blends may be very rewarding in this regard. In particu

Decomposition of phosphonofluoridates on glass

Autor: William T. Beaudry, Linda L. Szafraniec, J. M. Albizo, J. Richard Ward, Joseph W. Hovanec

Publikováno v: Journal of Fluorine Chemistry. 51:277-282

Neat droplets of O,O-diisopropylphosphorofluoridate (DFP) and O-1,2,2-trimethylpropyl methylphosphonofluoridate (Soman) decompose on glass. In thirty hours at room temperature over 40% of the Soman has been decomposed while nearly 15% of the DFP has

On the mechanism of phosphono or phosphorofluoridate hydrolysis catalyzed by transition metal ions

Autor: Joseph W. Hovanec, J. Richard Ward, William T. Beaudry, Linda L. Szafraniec

Publikováno v: Journal of Molecular Catalysis. 58:373-378

Transition metal ions, such as manganese(II) or copper(II), catalyze the hydrolysis of O -isopropyl methylphosphonofluoridate (sarin) or O , O' -diisopropyl phosphorofluoridate (DFP). The rate law for the catalyzed path is first order in ester, metal

Polymer-bound iodosobenzoate reagents for the cleavage of reactive phosphates

Autor: H. Dupont Durst, Joseph W. Hovanec, Robert A. Moss, Durgadas Bolikal

Publikováno v: Tetrahedron Letters. 29:2433-2436

Two polymer-bound iodosobenzoate derivatives have been prepared and found to be phosphorolytically active against both p -nitrophenyldiphenyl phosphate and the nerve agent, Soman.

Copper chloride - cyanopyridine complexes as catalysts for the decomposition of fluorophosphonate esters

Autor: Joseph W. Hovanec, H. D. Durst, J. M. Albizo, Rick J. Offerman, J. R. Ward, Alan R. Katritzky

Publikováno v: Journal of Fluorine Chemistry. 44:121-131

We have synthesized a number of copper complexes of O-alkylpyridine-2-carboximidates from the reaction of 2-cyanopyridine, copper(II) chloride dihydrate and various alcohols. These compounds have been tested as catalysts for the decomposition of the

Spontaneous reactivation of acetylcholinesterase following organophosphate inhibition

Autor: Karl W. Lanks, Claire N. Lieske, Clarence A. Broomfield, George M. Steinberg, Joseph W. Hovanec

Publikováno v: Biochimica et Biophysica Acta (BBA) - Enzymology. 483:312-319

The first kinetic studies on the spontaneous reactivation of Sarin-inhibited acetylcholinesterase (ascetylcholine hydrolase, EC 3.1.1.7) are reported. With increasing pH the extent of reactivation increases while the observed rate constant decreases.
