一般說明

我们致力于为您带来更加绿色的替代产品,这些产品遵守一项或多项绿色化学12项原则。作为一种更绿色溶剂,庚烷是己烷的环保替代品,可应用于HPLC和GC,成为“更安全的溶剂和助剂”。点击此处以获取更多信息。

庚烷(n-Heptane)是内燃机燃料中辛烷等级评定的主要参考燃料(PRF)。据报道,其十六烷值为56。其在流动反应器、激波管和快速压缩机中氧化的机制和动力学研究已被报道。研究了其在不同温度和压力条件下的热分解。研究了在氧化镁负载型钒催化剂存在下的氧化脱氢反应。据报道,n-庚烷的Hβ沸石(MoP/Hβ)催化加氢异构化上负载的磷化钼通过掺杂再生金属而得到增强(Cr、Ni或Ce)。

應用
