【摘要】 过氧化氢作为典型绿色基础化学品，其主流生产技术蒽醌法中，2-叔戊基蒽醌因优异的溶解与反应性能，有望取代2-乙基蒽醌成为主要工作载体。现有2-烷基蒽醌生产工艺苯酐法污染严重，不符合绿色发展需求。提出蒽烷基化-氧化法制备2-叔戊基蒽醌，重点探究蒽烷基化制备2-叔戊基蒽的工艺。通过系统研究反应温度、催化剂用量、原料与溶剂配比、蒽与戊烯配比、戊烯进料时间等关键参数对反应转化率及产物分布的影响，揭示反应机理与规律。结果表明，蒽烷基化产物呈同系物分布，主产物为2-叔戊基蒽，副产物为不同烷烃链取代的同系物；反应遵循亲电取代与正碳离子机理，副产物源于C_5⁺与戊烯聚合生成的C_10⁺经异构及β-断裂反应；确定了优化工艺条件，为提高主产物选择性提供方向。本研究为2-叔戊基蒽醌的绿色化生产奠定理论与技术基础。更多还原

【Abstract】 Hydrogen peroxide, as a typical green basic chemical, is mainly produced via the anthraquinone process. In this process, 2-tert-pentyl anthraquinone is expected to replace 2-ethyl anthraquinone as the main working carrier due to its excellent solubility and reactivity. The existing production process of 2-alkyl anthraquinone, the phthalic anhydride method, is highly polluting and does not meet the requirements of green development. This study proposes the anthracene alkylation-oxidation method to prepare 2-tert-pentyl anthraquinone, focusing on exploring the process of anthracene alkylation to prepare 2-tert-pentyl anthracene. Through systematic research on the influence of key parameters such as reaction temperature, catalyst dosage, ratio of raw materials and solvents, ratio of anthracene to pentene, and pentene feed time on reaction conversion and product distribution, the reaction mechanism and rules are revealed. The results show that the anthracene alkylation products are distributed in homologues, with the main product being 2-tert-pentyl anthracene and the by-products being homologues with different alkyl chain substitutions; the reaction follows the electrophilic substitution and carbocation mechanism, and the by-products are derived from the isomerization and β-bond cleavage reactions of C_10⁺ formed by the polymerization of C_5⁺ and pentene; the optimized process conditions are determined, providing a direction for improving the selectivity of the main product. This study lays a theoretical and technical foundation for the green production of 2-tert-pentyl anthraquinone.更多还原
