- W332519948 abstract "Abstract : The objective of this research was to characterize the effects of the quaternary ammonium compound, dodecyldimethyl(3-sulfopropyl)ammonium hydroxide (DDSAH), with respect to its effects on the dechlorination of HD. It was previously observed that this compound, as well as several other quaternary ammonium and phosphonium compounds, increased the rate of HD dechlorination. The objective of this study was to quantitate the effects of DDSAH under a variety of conditions of concentration, temperature, and pH and to determine if the effect was in fact catalytic. In general, the effects of DDSAH were relatively insensitive to pH over the range of 6.0 to 8.5, and relatively more sensitive to temperature, in that the effects on the dechlorination rate increased fairly sharply above 35 deg C. With respect to DDSAH concentration, effects varied less than three-fold over a 1000-fold concentration range between 0.01 and 10 mg/mL. The effects of HD concentration varied about three-fold between 0.5 and 5 mg/mL. Evidence for catalysis was based on the observance of a 75% dechlorination rate increase resulting from the addition of 1.5 mM DDSAH to a 16 mM HD reaction." @default.
