“…Until recently, the availability of a single, consistent, universally accepted chemical compatibility tool has eluded the chemical industry and has been an ongoing, strategic need. Due to the collaboration of several organizations both industry and governmental, the Chemical Reactivity Worksheet tool ((CRW 4.0) was developed to fill this need and detailed descriptions of its' design scenario and limitations are described in prior papers . The CRW was created originally by the National Oceanic and Atmospheric Administration, NOAA, for prediction of chemical hazards that may exist during a chemical spill event involving multiple chemicals.…”

Chemical compatibility is a key consideration throughout the chemical industry wherever two or more chemicals have the potential to mix, either inadvertently or by design. One of the most comprehensive tools available for determining chemical compatibility, the NOAA Chemical Reactivity Worksheet (CRW), has gained significant traction since the release of the third version (CRW3) in 2012. In 3 years, this free software has been downloaded >200,000 times and has become the chemical compatibility tool of choice at many organizations. As a result of an ongoing partnership between the National Oceanic and Atmospheric Administration (NOAA), The Dow Chemical Company, The Center for Chemical Process Safety (CCPS), Materials Technology Institute (MTI) and other industrial/academic/government volunteers, a fourth version of the CRW (CRW4) has been developed. The expanded capabilities of this new version include a materials of construction section, improved import/exporting/data sharing capabilities, additional reactive groups to aid in determining compatibility decisions, several user interface enhancements, along with the correction of minor issues found in the CRW3. This article will describe past development, the new features included in the CRW4, followed by a brief discussion of future development plans for the software tool. Such developments should solidify this tool's position as the gold standard within the chemical industry for determining chemical hazards. © 2016 American Institute of Chemical Engineers Process Saf Prog 36: 24–29, 2017

“…25 Unlike previous charts, software programs contain libraries of technical data with information and recommendations pertaining to specific hazardous chemicals (e.g., hydroxide peroxide or sulfuric acid), and they may be used for the prediction of reactivity. 26 In past years, several enhancements have been incorporated to help with the generation and presentation of chemical compatibility charts but, even if they can potentially become standards for the chemical industry, 27 none of these methods is exhaustive. Indeed, they can indicate consequences of the incompatibility, allowing users to apply adequate mitigation measures, but they do not explain exactly how the incompatibility drives the undesired reaction scheme, in terms of thermodynamic data.…”

Modeling chemical incompatibility : the ammonium nitrate and sodium salt of dichloroisocyanuric acid as a case study. AbstractThe dramatic accident involving ammonium nitrate (AN) that took place at Toulouse in September 2001 has once again focused attention on the hazards pertaining to chemical incompatibility in industrial environment. To complete the experimental results, a detailed theoretical study was performed in order to better understand the involved mechanisms, considering the reaction between ammonium nitrate and the sodium salt of dichloroisocyanuric acid (SDIC). Starting from theoretical results obtained for the pure reactants, the gas-phase decomposition mechanism of the mixture was investigated and fully characterized by means of Density Functional Theory (DFT) calculations. Beyond the complete characterization, in terms of intermediate structures and energies, of the decomposition pathways, our results evidenced as anticipated the role of water in catalyzing the decomposition reaction, through a significant decrease of the activation energy of the rate determining step. These results, in qualitative agreement with the calorimetric experiments, pointed out the instability of the AN-SDIC wet mixture and the underpinning incompatibility mechanism between these two chemicals.
