This manuscript explores the synthesis of new cyclo-peroxide compounds (CPs) through a systematic approach involving 10 different ketones and two concentrations of HO. Following spectroscopic analysis and calorimetric tests on 10 selected compounds, the percentage of Power Index (%PI) was calculated. The study introduces a computational methodology based on the Iterative Stochastic Elimination (ISE) algorithm. The newly constructed ISE model, with demonstrated robust predictive capabilities indicated by its statistical parameters, was employed to screen and score the CPs, assessing their potential as energetic materials. Comparison between %PI obtained experimentally, and the ISE index derived computationally revealed consistent assessments of the new CPs' energetic potential. The research emphasizes that, particularly in the synthesis of cyclic peroxides, the ISE model is a preferable and efficient tool for predicting a compound's potential as an energetic substance. Utilizing the ISE model ensures faster, more cost-effective, and safer decision-making in experimental examinations, focusing attention only on compounds with the highest ISE scores. Furthermore, the manuscript suggests an intriguing avenue for future research by proposing the investigation of ester nitrates. The study advocates a comprehensive approach that combines experimental methods (synthesis, spectroscopy, and DSC) with computational evaluation using the ISE model to identify potential high-energy compounds. This integrated approach promises to enhance the efficiency and reliability of the energetic materials discovery process.
本手稿通过一种系统方法探索新型环过氧化物化合物(CPs)的合成,该方法涉及10种不同的酮和两种浓度的过氧化氢。在对10种选定化合物进行光谱分析和量热测试后,计算了功率指数百分比(%PI)。该研究引入了一种基于迭代随机消除(ISE)算法的计算方法。新构建的ISE模型具有强大的预测能力,其统计参数表明了这一点,该模型被用于筛选和评分CPs,评估它们作为含能材料的潜力。实验获得的%PI与通过计算得出的ISE指数之间的比较,揭示了对新型CPs含能潜力的一致评估。该研究强调,特别是在环状过氧化物的合成中,ISE模型是预测化合物作为含能物质潜力的一种优选且有效的工具。使用ISE模型可确保在实验检测中做出更快、更具成本效益且更安全的决策,仅关注ISE得分最高的化合物。此外,该手稿通过提议对硝酸酯进行研究,为未来研究提出了一条有趣的途径。该研究提倡一种综合方法,即将实验方法(合成、光谱学和差示扫描量热法)与使用ISE模型的计算评估相结合,以识别潜在的高能化合物。这种综合方法有望提高含能材料发现过程的效率和可靠性。
