内容記述 | In mixing hazard evaluations, a smaller scale is preferred for safety reasons and in order to conserve the samples. We have developed a small-scale Dewar vessel test (SDVT) that measures the amount of heat from a temperature change upon the mixing of two chemicals. In general, the accuracy of small-scale tests is negatively impacted by heat loss. The purpose of this study is to establish experimental conditions and to validate the reproducibility and accuracy of our small-scale test. The adjustable experimental parameters for SDVT are: position of sample injection, amount of sample, stirring speed, and surrounding temperature. These conditions were optimized for the measurement of the heat of neutralization of hydrochloric acid and sodium hydroxide. Under the optimized experimental conditions, the reproducibility was validated by measurement of the heat of hydration between acetic acid anhydride and water. The relative standard deviation of the maximum temperature change was 3.1%. To validate the accuracy, the heat of reaction between the neutralization reaction and hydration reaction was calculated. The heat of reaction was in good agreement with the theoretical value. Thus, the SDVT has sufficient accuracy and reproducibility to serve as a screening method for the mixing hazard of chemicals. | |||||
