TL;DR: In this article, it was shown that both methanol and formic acid are impurities found in chlorine dioxide solutions produced industrially by the reaction of methanols and sodium chlorate, and each impurity influences the apparent concentration of chlorine in these solutions.
Abstract: Both methanol and formic acid are impurities found in chlorine dioxide solutions produced industrially by the reaction of methanol and sodium chlorate. This work shows that each of these impurities influences the apparent concentration of chlorine in these solutions. (1) Formic acid reacts with chlorine; and (2) methanol interferes with the arsenite titration procedure commonly used for chlorine analysis. Rates of reaction of chlorine with formic acid were measured in chlorine dioxide solutions prepared in the laboratory. The reaction is approximately first order in chlorine and in formic acid. The activation energy is 15 kcal/mol. Rates of reaction of chlorine with methanol were comparatively less significant under similar experimental conditions; however, methanol reacted very rapidly under basic conditions of the arsenite titration procedure, leading to false measurements of chlorine concentration.

TL;DR: In this article, a novel method of producing metal chlorates is described which involves the reaction of ammonium chlorate with metal carbonates and/or metal bicarbonates.
Abstract: A novel method of producing metal chlorates is described which involves the reaction of ammonium chlorate with metal carbonates and/or metal bicarbonates. The reaction yields extremely pure metal chlorate, as well as ammonia and carbon dioxide by-products. These by-products combine to produce ammonium bicarbonate. The ammonium bicarbonate may then be reacted with sodium chlorate to produce ammonium chlorate, which may be recycled for use in the production of metal chlorates.

TL;DR: In this article, single crystals of sodium chlorate were grown in the presence of selective impurities, and the morphology of these crystals changed completely from cubic to tetrahedral form.
Abstract: Single crystals of sodium chlorate were grown in the presence of selective impurities. The morphology of these crystals changed completely from cubic to tetrahedral form. Experiments were performed in the presence of different concentrations of impurities to ascertain their role in modifying the habit of these crystals. The presence of impurity in the solution was found to affect the habit of the crystals, although it does not appear to enter into the lattice.

TL;DR: In this paper, it was shown that the effect of these flame returnards when added to CHLORATE CONTAINING SOLUTIONS does not affect from the effect from the function of the chlorate solution in ELECTROCHEMICAL MACHINING, MILLING, and GRINDING OPERATIONS.
Abstract: AN ALKALI METAL SILICATE ALONE OR IN COMBINATION WITH ONE OR MORE ALKALI METAL OR AMMONIUM-CHROMATE, HYDROXIDE, CARBONATE, SULFATE, BORATE AND PHOSPHATE WHEN ADDED TO SOLUTIONS OF AN ALKALI METAL OR AMMONIUM CHLORATE IN MINOR AMOUNTS WILL ACT AS FLAME RETARDANTS FOR COMBUSTIBLE ORGANIC MATERIAL UPON WHICH THE CHLORATE HAS BEEN DEPOSITED. THE FUNCTION OF THESE FLAME RETARDANTS WHEN ADDED TO CHLORATE CONTAINING SOLUTIONS DOES NOT DETACT FROM THE FUNCTION OF THE CHLORATE SOLUTION IN ELECTROCHEMICAL MACHINING, MILLING AND GRINDING OPERATIONS OR IN AGRICULTURAL APPLICATIONS.

TL;DR: Chlorine dioxide is a yellow to red, unpleasant smelling, irritating gas with a vapor density of approximately 2.4 grams per liter at 30 mm. of mercury partial pressure, and its aqueous solutions are decomposed by light, forming perchloric and chloric acids, oxygen and water as discussed by the authors.
Abstract: AT ORDINARY temperatures and pressures, chlorine dioxide is a yellow to red, unpleasant smelling, irritating gas, with a vapor density of approximately 2.4. It is photochemically active, soluble in water to the extent of 2.9 grams per liter at 30 mm. of mercury partial pressure, and its aqueous solutions are decomposed by light, forming perchloric and chloric acids, oxygen, and water. By comparison with other related chemicals, such as chlorine, sodium hypochlorite, and sodium chlorate, chlorine dioxide is not unusually hazardous. Its oxidizing power, stated in terms of available chlorine, is 2.5 times that of chlorine itself. This is illustrated on a molecular basis as follows: CIO 2 + 2 1 / 2 H 2 → HC1 + 2H 2 O CI 2 + H 2 → 2HC1 Production Processes Because of its instability, chlorine dioxide cannot he produced in bulk and stored until wanted; it must be generated in very low concentrations at the point of use, and consumed immediately. This was ...
