  • Working with Hazardous Chemicals
    A Publication of Reliable Methods for the Preparation of Organic Compounds Working with Hazardous Chemicals The procedures in Organic Syntheses are intended for use only by persons with proper training in experimental organic chemistry. All hazardous materials should be handled using the standard procedures for work with chemicals described in references such as "Prudent Practices in the Laboratory" (The National Academies Press, Washington, D.C., 2011; the full text can be accessed free of charge at http://www.nap.edu/catalog.php?record_id=12654). All chemical waste should be disposed of in accordance with local regulations. For general guidelines for the management of chemical waste, see Chapter 8 of Prudent Practices. In some articles in Organic Syntheses, chemical-specific hazards are highlighted in red “Caution Notes” within a procedure. It is important to recognize that the absence of a caution note does not imply that no significant hazards are associated with the chemicals involved in that procedure. Prior to performing a reaction, a thorough risk assessment should be carried out that includes a review of the potential hazards associated with each chemical and experimental operation on the scale that is planned for the procedure. Guidelines for carrying out a risk assessment and for analyzing the hazards associated with chemicals can be found in Chapter 4 of Prudent Practices. The procedures described in Organic Syntheses are provided as published and are conducted at one's own risk.

  • Template COVID-19
    PAHO Does Not Recommend Taking Products that Contain Chlorine Dioxide, Sodium Chlorite, Sodium Hypochlorite, or Derivatives 16 July 2020 The information included in this note reflects the available evidence at the date of publication. KEY MESSAGES • The Pan American Health Organization (PAHO) does not recommend oral or parenteral use of chlorine dioxide or sodium chlorite-based products for patients with suspected or diagnosed COVID-19 or for anyone else. There is no evidence of their effectiveness and the ingestion or inhalation of such products could cause serious adverse effects. • People’s safety should be the main objective of any health decision or intervention. • PAHO recommends strengthened reporting to the national drug regulatory authority or to the office of the Ministry of Health responsible for drug regulation in the event of any adverse event linked to the use of these products. PAHO also recommends that products containing chlorine dioxide, chlorine derivatives, or any other substance presented as a treatment for COVID-19 should be reported. • The health authorities should monitor media marketing of products claiming to be therapies for COVID-19 in order to take the appropriate actions. Information on the subject Context • Chlorine dioxide is a yellow or reddish-yellow gas used as bleach in paper manufacturing, in public water treatment plants, and for the decontamination of buildings. Chlorine dioxide reacts with water to generate chlorite ions. Both chemical species are highly reactive, which means that they have capacity to eliminate bacteria and other microorganisms in aqueous media (Agency for Toxic Substances and Disease Registry [ATSDR], 2004). • This gas has been used as a disinfectant in low concentrations for the treatment of water (WHO: 2008, 2016) and in clinical trials for buccal antisepsis (National Library of Medicine, 2020).

  • Guidelines for Drinking-Water Quality, Fourth Edition
    12. CHEMICAL FACT SHEETS Assessment date 1993 Principal reference WHO (2003) Chlorine in drinking-water In humans and experimental animals exposed to chlorine in drinking-water, no specific adverse treatment-related effects have been observed. IARC has classified h ypochlorite in Group 3 (not classifiable as to its carcinogenicity to humans). Chlorite and chlorate Chlorite and chlorate are disinfection by-products resulting from the use of chlorine dioxide as a disinfectant and for odour and taste control in water. Chlorine dioxide is also used as a bleaching agent for cellulose, paper pulp, flour and oils. Sodium chlorite and sodium chlorate are both used in the production of chlorine dioxide as well as for other commercial purposes. Chlorine dioxide rapidly decomposes into chlorite, chlorate and chloride ions in treated water, chlorite being the predominant species; this reaction is favoured by alkaline conditions. The major route of environmental ex- posure to chlorine dioxide, sodium chlorite and sodium chlorate is through drinking- water. Chlorate is also formed in sodium hypochlorite solution that is stored for long periods, particularly at high ambient temperatures. Provisional guideline values Chlorite: 0.7 mg/l (700 µg/l) Chlorate: 0.7 mg/l (700 µg/l) The guideline values for chlorite and chlorate are designated as provisional because use of chlorine dioxide as a disinfectant may result in the chlorite and chlorate guideline values being exceeded, and difficulties in meeting the guideline value must never be a reason for compromising adequate disinfection. Occurrence Levels of chlorite in water reported in one study ranged from 3.2 to 7.0 mg/l; however, the combined levels will not exceed the dose of chlorine dioxide applied.

  • Press Release
    Press release Medicines Control Council warns against the use of the unregistered medicine, Miracle Mineral Solution (MMS) and similar products for the treatment of medical conditions Date: 15 May 2016 At its 77th meeting on 21-22 April 2016, the Medicines Control Council (MCC) expressed their concern over the use of an unregistered medicine sold as Miracle Mineral Solution (MMS) by the public. Miracle Mineral Solution (MMS) has been claimed to be effective in the treatment of various medical conditions, including HIV/AIDS, cancer, autism, type 1 and type 2 diabetes mellitus. It is claimed that Miracle Mineral Solution (MMS) can remove impurities from the body. Miracle Mineral Solution (MMS) is allegedly sold by the Genesis II Church, using a pyramid-type marketing and distribution scheme. What is Miracle Mineral Solution (MMS)? Miracle Mineral Solution (MMS) is presented as two separate bottles, one purporting to contain a mixture of herbs and sodium chlorite, and the second purporting to contain citric acid. In accordance with the directions for use, when the two solutions are mixed, chlorine is released. The manufacturer, sellers and distributors claim that the released chlorine will target the patient’s affected cells (such as those cells affected by HIV or cancer) and remove those cells from the body. Sodium chlorite (not to be confused with table salt – sodium chloride) is commonly used as a bleach. It is included in disinfectants or bleaching agents for domestic use. It is also used to control slime and bacterial formation in water systems used, such as at power plants, pulp and paper mills.

Although arabinoxylans (AX) from different sources may yield polyuronides with diverse TEMPO-oxidation properties due to their variable arabinose (Araf) substitution patterns, information of the TEMPO-oxidation of AX Arabinuronoxylan on its structure remains scarce. We oxidized AX using various TEMPO:NaClO2:NaOCl ratios. A TEMPO:NaClO2: Arabinuronic acid NaOCl ratio of 1.0:2.6:0.4 per mol of Ara gave an oxidized-AX with high molecular weight, minimal effect on xylose appearance, and comprising charged side chains. Although NMR analyses unveiled arabinuronic acid (AraAf) as the only oxidation product in the oxidized-AX, accurate AraA quantification is still challenging. Linkage analysis showed that > 75 % of the β-(1→4)-xylan backbone remained single-substituted at position O-3 of Xyl similarly to native AX. TEMPO-oxidation of AX can be considered a promising approach to obtain ara­ binuronoxylans with a substitution pattern resembling its parental AX.

[email protected] The kinetics of the reaction between sodium chlorite and hydrochloric acid is studied at various temperatures and molar concentrations of chlorite and acid at low concentrations. The reaction rate law is established, and macrokinetics formula is obtained. Reaction has been found 1 and 1.39 order with respect to chlorite and hydrochloric acid respectively when preparing chloride dioxide using low concentrations of sodium chlorite and hydrochloric acid. The temperature dependence of the reaction is also investigated and pre-exponential Arrhenius parameter as well as activation energy are determined. 1. Introduction Chloride dioxide (ClO2) is usually used as an oxidant for pulp bleaching and disinfection. For its application in water treatment, chloride dioxide can achieve a good disinfection effect without producing chlorinated organic matters such as trihalomethanes (THMs) and chlorophenol that are carcinogens or mutagens, which was reported by Yu and Zhang (2012). Under normal temperature, chloride dioxide exists as a gas that has an excellent antibacterial and disinfection effect on a variety of microorganisms.

  • Sids Initial Assessment Profile
    SIAM 23, 17-20 October 2006 BIAC/ICCA SIDS INITIAL ASSESSMENT PROFILE Sodium chlorite 7758-19-2 CAS No. Chlorine dioxide 10049-04-4 Chemical Name Category Sodium chlorite and chlorine dioxide Sodium chlorite Na ClO2 Molecular Formula Chlorine dioxide ClO2 SUMMARY CONCLUSIONS OF THE SIAR Category justification Chlorine dioxide and sodium chlorite are characterized together in this dossier because studies conducted with chlorite, the predominant reduction product of chlorine dioxide, are considered to be relevant in characterizing the toxicity of chlorine dioxide. In addition, studies conducted with chlorine dioxide may be relevant to characterize the toxicity of chlorite. Chlorine dioxide is fairly unstable and dissociates predominantly into - - - chlorite (ClO2 ) and chloride (Cl ), and to a lesser extent, chlorate (ClO3 ). There is a ready interconversion among these species in both water and the human gut. Therefore, what exists in water or the body is a mixture of these chemical species. Toxicity information on sodium chlorite is also relevant and appropriate for assessing the effects of chlorine dioxide in man and the environment and vice versa. This category approach does not take into account local effects that would occur by dermal or inhalation exposure as they are specific to each substance. Human Health Both sodium chlorite and chlorine dioxide are rapidly absorbed following ingestion with chlorine dioxide being converted into chlorite and chloride ions with chlorate as a minor by-product. This document may only be reproduced integrally. The conclusions and recommendations (and their rationale) in this document are intended to be mutually supportive, and should be understood and interpreted together.
