Chlorine-38 for chlorine substitution in geometric and diastereomeric compounds: mechanism and stereochemistry
In order to determine how solvents control the stereochemical course of the hot substitution reactions, the stereochemistry of the energetic ³⁸Cl for Cl was studied in diastereomeric 1,2-dichloro-1,2-difluoroethane and the geometric isomers of 1,2-dichlorohexa-fluorocyclobutane. In each system, the …

Treatment of algae-induced tastes and odors by chlorine, chlorine dioxide and permanganate
Chlorine (Cl₂(sq»' chlorine dioxide (ClO₂ ) and potassium permanganate (KMnO₄) were evaluated as oxidants for the removal of grassy and cucumber odors associated with the pure compounds, cis-3-hexenol and trans-2, cis-6-nonadienal, respectively, and for the removal of fishy odors associated with a …

Interactions Between Copper and Chlorine Disinfectants: Chlorine Decay, Chloramine Decay and Copper Pitting
Interactions between copper and chlorine disinfectants were examined from the perspective of disinfectant decay and copper pitting corrosion. Sparingly soluble cupric hydroxide catalyzed the rapid decay of free chlorine, which in turn, led to production of less soluble and more crystalline phases …

Destruction of algae-produced taste-and-odor compounds by chlorine, potassium permanganate, and chlorine dioxide
… was to determine the effect of three oxidants - chlorine, potassium permanganate, and chlorine dioxide - on solutions of pure odorous as well as nonodorous compounds and algal extracts containing a mixture of odor-related compounds. Oxidant dosages used were in the ranges expected during water …

Plume Dispersion Modeling of Chlorine Gas Released Due to Ballistic Attack on Chlorine-Carrying Railway Tanker
Hazardous dense gases such as chlorine are often transported throughout the United States in their liquid form in pressurized railway tankers. These tankers can hold up to 90 tons of liquid chlorine. A high-powered, ballistic attack on a chlorine-carrying tanker could cause devastating outcomes for …

A comparison of antichlors used in scrubbing chlorine and chlorine dioxide from bleach plant vent gases
A project was conducted to determine the relative effectiveness of several antichlors in regards to their Cl₂ and ClO₂ gaseous "scrubbing" capacity. Both a pilot study as well as full scale trials were completed. Work was done on a bleach plant-packed tower scrubber system at a kraft pulp and paper …

On the stereochemical course of the chlorine-38 for chlorine substitution in diastereomeric and enantiomeric compounds
The stereochemistry of the energetic ³⁸Cl for Cl substitution was studied in diastereomeric 2,4-dichloropentane and 2,3-dichlorobutane as well as in enantiomeric 2-chloro-1-propanol in solution. It was found that the stereochemical course of the substitution reaction exhibits a strong dependence on …

Determination of chlorine by fluorescence quenching
Chlorine is used extensively in the chemical industry and for disinfection of drinking water. Many methods have been reported for the determination of chlorine species. Fluorescence quenching to determine chlorine is a promising method because of its high sensitivity and selectivity. This study …

Molecular recognition of chlorine-doped polypyrrole
… surface display of scFv libraries the surface of chlorine-doped polypyrrole (PPyCl) has been modified to facilitate binding of neuronal phenotype cells. The selection of peptides using phage display found a surface specific recognition peptide (T59) that was made bivalent by altering the …

The Effects of Chlorine on Boiler Corrosion
The amount of corrosion of six metal samples was measured by a change in weight over time. The simulated flue gas stream consisted of 0.2% SO2,14% C02 / and 4% O2, with the HC1 percentage varied from 0.2% to 0.0% and the balance of gas being N2. A Lindbergh Three Temperature Tube Furnace was used …

Chlorine in ground water : stable isotope distribution
Eighty years of chlorine atomic weight measurements revealed no variation of the stable isotope ratio, 37C1/ 35C1 (with precision up to 1.0%.) in natural materials. This result is not surprising because chlorine occurs in relatively few compounds, has a strong affinity for the liquid phase, occurs …

The chlorine ion diffusion in potassium chloride
The diffusion coefficient of the chlorine ion in Harshaw potassium chloride crystals and in potassium chloride crystals containing strontium has been measured. The measurements were made with radioactive chlorine 36 and sectioning techniques. The chlorine ion diffusion coefficient of the Harshaw …
