January 1, 1995 - The aim of this work was to demonstrate that dimethylsulfoxide (DMSO) is an excellent masking agent for aqueous chlorine in the determination of other oxychlorines. By the addition of excess DMSO, specific absorbance of free chlorine disappeared, and the oxidation of iodide to iodine by chlorine ...

August 1, 1993 - For the selective determination of aqueous chlorine dioxide(ClO2) in the mixed solution with chlorine, dimethylsulfoxide(DMSO) was used as a masking agent for chlorine.

Also, many flavorants contain reactive alkenes such as d-limonene that can degrade the chlorine. Additionally when d-limonene is oxidized by some oxidants, the resultant derivatives produced can be undesirable as a possible sensitizer. the example masking agents used herein can mask the taste and odor of chlorine in the treated drinking water while preserving the effects of the disinfecting agent, such as chlorine.

The masking agent can be a chlorine-compatible masking agent or flavorant, such as a citrus fruit derived flavor. The composition can also include a substrate. The substrate can be a clay, zeolite, water-soluble carrier, water-insoluble carrier, or mixtures thereof.

Under increased pressure or at temperatures below -30ºF, it is a clear, amber-colored liquid. It is generally shipped in steel cylinders as a compressed liquid. Chlorine is only slightly soluble in water, but on contact with moisture it forms hypochlorous acid (HClO) and hydrochloric acid ...

July 20, 2026 - This chlorine-releasing compound is the most common bleaching and disinfection compound. A dilute (3–6%) aqueous solution in water, historically known as Eau de Labarraque or "Labarraque's water", is widely marketed as a household cleaning product, under the name "liquid bleach" or simply "bleach". More concentrated solutions are used to disinfect drinking water and as bleaching agents ...

NIOSH-approved respirator masks for chemical protection with replaceable filters.

April 8, 2023 - When soft washing in areas of poor ventilation a face mask is essential PPE that offers protection from gas and vapours such as chlorine gas that’s liberated from Sodium hypochlorite based softwash solutions.

Disposable FFP2/FFP3 respirators are designed to filter particles (dust, mists, some aerosols). They do not filter gases and vapours such as chlorine or solvent vapours from cleaning agents.

Chlorine is an inorganic gas that can cause chest pains, shortness of breath, or irritate the mucus membrane. Masks are vital for workers in water purification, synthetic rubber manufacturing, and similar fields.

July 28, 2026 - Replace cartridges immediately if you ever detect chlorine odor, taste, or throat/eye irritation through the respirator. Key limits to design your program around: OSHA PEL 1 ppm ceiling, NIOSH REL 0.5 ppm (15-min ceiling), IDLH 10 ppm. Half-mask APR = assigned protection factor 10; full-face APR = 50.

October 19, 2017 - Moreover, TMB was as effective as sodium thiosulfate when used as a quencher in kinetic experiments involving the chlorination of 2,4-dichlorophenol and bromination of anisole. By quantifying TMB and its halogenated products in the quenched samples, we were also able to determine the concentrations of free halogens that were present at the time of quenching. Findings from our work show that TMB can serve as an effective quencher in aqueous halogenation experiments that involve redox-labile analytes and/or that require selective quantification of residual free halogens.

September 12, 2026 - Cl2 and Cl+ equivalents are electrophilic reagents normally used to add to unsaturated C-C bonds, take part in electrophilic substitution reactions with aromatics/heteroaromatics, or react with acidic C-H bonds.

US-5262466-A chemical patent summary

Treatment: Chlorine gas is a pulmonary irritant with intermediate water solubility that causes acute damage in the upper and lower respiratory tract. Chlorine gas was used as a chemical weapon in World War I.

July 20, 2026 - For applying chlorine bleach to attic mold or any enclosed-space cleanup, use a full-face respirator (like the 3M 6800) paired with a multi-gas plus P100 filter combination (like the 3M 60926).

A residual must be maintained after the chlorine dioxide demand has been met, to ensure effective control of microbiological growth. The chemical behavior and oxidation characteristics of aqueous chlorine dioxide are not well understood because of the difficulty in differentiating aqueous ...
