TL;DR: Sodium chlorate residues were stable (P > 0.05) in frozen tomato and cantaloupe homogenates during storage for 119 days at -24 °C.
Abstract: The objective of this study was to determine the stability of sodium chlorate in frozen (−24 °C) tomato or cantaloupe homogenates for up to 17 weeks (119 days). Chlorate stability was assessed by ultraperformance liquid chromatography–mass spectrometry (UPLC-MS/MS) at two fortification levels (80 or 600 ng/g for tomato and 200 or 3000 ng/g for cantaloupe, n = 3 each) for each fruit after storage for 0, 1, 7, 14, 28, 56, or 119 d. Within matrix type, chlorate recovery was determined by fortifying duplicate blank homogenate samples on the day of analysis with the same concentrations used for the stability samples. Chlorate limits of quantitation for cantaloupe and tomato matrices were 30 and 60 ng/g, respectively. Sodium chlorate residues were stable (P > 0.05) in frozen tomato and cantaloupe homogenates during storage for 119 days at −24 °C.

TL;DR: In this article, a chlorate oxygen candle with stable combustion for oxygen supply and a preparation method of the chlorate oxide candle is presented. But the main candle body is not included in the preparation of the combustible medicine layer.
Abstract: The invention discloses a chlorate oxygen candle with stable combustion for oxygen supply and a preparation method of the chlorate oxygen candle. The chlorate oxygen candle comprises a main candle body and a combustible medicine layer, wherein the main candle body is prepared from, by weight, 70-88 parts of sodium chlorate, 1-15 parts of potassium perchlorate, 2-6 parts of fuel, 0.5-5 parts of acatalyst, 1-8 parts of a chlorine inhibitor, 1-8 parts of a binder and 2-5 parts of a broken metal piece; the combustible medicine layer is prepared from, by weight, 75-86 parts of sodium chlorate, 1-5 parts of potassium perchlorate, 2-10 parts of fuel, 1-5 parts of a catalyst, 2-8 parts of a chlorine inhibitor and 0.5-4 parts of a broken metal piece. The preparation method includes the steps: preparation of the main candle body, namely evenly dry-blending the raw materials added with 0.5% of distilled water by evenly wet-blending; preparation of the combustible medicine layer, namely evenlydry-blending the raw materials added with 0.5% of distilled water by evenly wet-blending; loading a mould press between positions under the main candle body and above the combustible medicine layer for compression molding prior to placing in an oven for 14 hours at 120-140DEG C after demolding. The chlorate oxygen candle is good in heat-transfer performance, and heat generated from combustion cannot be accumulated to cause combustion to increase; post-combustion residues are less prone to flow, and stable combustion for oxygen supply is guaranteed.

TL;DR: In this paper, a laser Raman spectrometer has been used to study the variation of the frequencies and half-widths as a function of temperature (100 to 450°K) of five lines in the Raman spectrum of a sodium chlorate single crystal.
Abstract: A laser Raman spectrometer has been constructed. The system includes an optimized focused geometry for illuminating the sample and collecting the scattered radiation. This system has been used to study the variation of the frequencies and half-widths as a function of temperature (100 to 450°K) of five lines in the Raman spectrum of a sodium chlorate single crystal. The 68, 134, and 180 cm lines represent vibrations involving relative motion of the sodium and chlorate ions, while the 486 and 938 cm" lines represent vibrations involving only internal motions of the chlorate ion. A simple form of Grllneisen's law seems adequate to describe the variation of the frequency as a function of volume. It was found that the product of the coefficient of expansion and the Grtlneisen constant was constant over the temperature range studied. This implies that the logarithm of the Debye temperature is a linear function of temperature. The Grtlneisen constant for the low frequency vibrations was found to be quite different from the constant for the chlorate vibrations. If one allows for variation of compressibility with temperature, a general description of the half-width variation can be described by a simple statistical model.

TL;DR: The catalytic effect of cobalt powder on chlorate decomposition has been confirmed as discussed by the authors, and it has been shown that the complete elimination of fuel is not a vital factor in the improved performance of catalyzed candles.
Abstract: The catalytic effect of cobalt powder on chlorate decomposition has been confirmed. Catalysis is enhanced by oxidation of the metal during burning. Catalysts other than cobalt compounds should also be effective; the complete elimination of fuel has shown that the oxidation of cobalt during decomposition is not a vital factor in the improved performance of catalyzed candles.
