Tabun scavengers based on hydroxamic acid containing cyclodextrins

Chemical Communications, 2013
Arrangement of several hydroxamic acid-derived substituents along the cavity of a cyclodextrin ring leads to compounds that detoxify tabun in TRIS-HCl buffer at physiological pH and 37.0 °C with half-times as low as 3 min.

Scavenging the Water Cation in Concentrated Acidic Solutions

The Journal of Physical Chemistry A, 2015
Picosecond pulse radiolysis techniques were used to observe the kinetics of the SO4(•-), H2PO4(•), Cl2(•-), and Br2(•-) species formed in the fast oxidation of concentrated and highly acidic solutions of SO4(2-), PO4(3-), Cl(-), and Br(-). Experimental results were compared with model predictions to gain insight into the possible mechanisms occurring ...

Investigation of Sulfide Scavengers in Well Acidizing Fluids

SPE International Symposium on Formation Damage Control, 2000
Abstract This paper describes the development of acidizing systems that use several different aldehyde-based sulfide suppression chemicals in conjunction with new acid corrosion inhibitors. Specific combinations of these chemicals have allowed the acid to dissolve FeS, suppress H2S and still enable the acid to be inhibited to industry ...

Nasal Secretion of the Ozone Scavenger Uric Acid

American Review of Respiratory Disease, 1993
Uric acid, an important scavenger of ozone, has been identified as the major low molecular weight antioxidant in baseline and cholinergically induced nasal secretions. The purpose of this study was to determine the specific tissue source of uric acid in airway secretions. The secretion of uric acid is increased by cholinergic stimulation and correlates

Hypochlorous acid scavenging properties of local mediterranean plant foods

Lipids, 2004
AbstractOxidative modification of low density lipoprotein (LDL) is involved in the pathogenesis of atherosclerosis and coronary heart disease, which are low in the Mediterranean area possibly due to a high dietary proportion of plant food. Ethanolic extracts were prepared from more than 120 Mediterranean edible plants collected in remote areas (which ...

Ambroxol Is a Scavenger of Hypochlorous Acid and Monochloramine

Pharmacology, 1994
Experimental studies have suggested that ambroxol, a drug clinically used to enhance pulmonary surfactant production, may also exert some anti-inflammatory effects, though specific mechanisms are not yet fully understood. Thus, potential scavenging properties of ambroxol towards the most toxic neutrophil-arising prooxidants hypochlorous acid and ...

New acid scavenger enhances PVC stabilization

Plastics, Additives and Compounding, 2009
The PVC industry has been involved in an active programme in recent years to phase out the use of lead stabilizers. Mixed metal stabilizers have been at the forefront of these developments. Now Dr Reiner Sauerwein of Nabaltec AG describes the introduction of a new inorganic co-stabilizer to the market and the potential benefits to the industry.

Scavenging of photoenols by acids and bases

Tetrahedron Letters, 1992
Abstract Photoenols generated by irradiation of ortho -methylacetophenone, ortho -methylbenzophenone and ortho -benzylbenzophenone are readily quenched by acids and bases. The rate constants for these reaction have been employing laser flash photolysis techniques.

Acid scavengers for polyolefins

1998
The transformation of a polyolefin material on its way from the reactor fluff to the finished article usually comprises several steps including processing operations at elevated temperatures. During these steps the polymer material suffers from various degradation processes caused by the combined influence of heat, shear and oxygen, which can ...

Free Radical Scavenging Properties of Conjugated Linoleic Acids

Journal of Agricultural and Food Chemistry, 2001
Conjugated linoleic acids (CLA) were investigated for free radical scavenging properties against the stable 2,2-diphenyl-1-picryhydrazyl radical (DPPH.) by electron spin resonance (ESR) spectrometry and spectrophotometric methods. ESR results demonstrated that CLA directly reacted and quenched free DPPH radicals in benzene, while spectrophotometric ...
