Hydrogen peroxide (H2O2) for industrial applications is manufactured through an indirect process that relies on the sequential reduction and reoxidation of quinone carriers. While highly effective, production is typically centralized and entails numerous energy-intensive concentration steps. Furthermore, the overhydrogenation of the quinone necessitates periodic replacement, leading to incomplete atom efficiency. These factors, in addition to the presence of propriety stabilizing agents and concerns associated with their separation from product streams, have driven interest in alternative technologies for chemical upgrading. The decoupling of oxidative transformations from commercially synthesized H2O2 may offer significant economic savings and a reduction in greenhouse gas emissions for several industrially relevant processes. Indeed, the production and utilization of the oxidant in situ, from the elements, would represent a positive step toward a more sustainable chemical synthesis sector, offering the potential for total atom efficiency, while avoiding the drawbacks associated with current industrial routes, which are inherently linked to commercial H2O2 production. Such interest is perhaps now more pertinent than ever given the rapidly improving viability of green hydrogen production.

使用原位产生的过氧化氢进行选择性氧化



用于工业应用的过氧化氢(H 2 O 2 )是通过依赖于醌载体的连续还原和再氧化的间接过程来制造的。虽然效率很高,但生产通常是集中的,并且需要许多能源密集型的集中步骤。此外,醌的过度氢化需要定期更换,导致原子效率不完全。除了适当的稳定剂的存在以及与其从产品流中分离相关的担忧之外,这些因素引起了人们对化学升级替代技术的兴趣。商业合成的H 2 O 2的氧化转化的解偶联可以为一些工业相关过程提供显着的经济节约并减少温室气体排放。事实上,从元素中原位生产和利用氧化剂将代表迈向更可持续的化学合成领域的积极一步,提供总原子效率的潜力,同时避免与当前工业路线相关的缺点,这些缺点本质上是与商业H 2 O 2生产相关。鉴于绿色氢生产的可行性迅速提高,这种兴趣现在可能比以往任何时候都更有意义。
