Oxidation of pentane
WebJun 2, 2024 · However, we noticed a rapid oxidation of this aldehyde between GC (directly recorded after CC) and NMR/GC-MS analysis (recording after 2 h). The compound C seemed to oxidize under atmospheric conditions—indeed, GC-MS and NMR analysis indicated the formation of corresponding acid: pin-2-en-8-oic acid ( E ) ( Figure 2 and Table 4 ). WebOxidation was accomplished by evacuating the tube, heating it to the set temperature (423 K–723 K, in 100 K increments), and introducing 12 SCCM (standard cubic centimeters per minute) of O for one hour. After oxidation, the samples were again stored in the glove box under an inert atmosphere.
