Under the action of a twofold excess of KOH and heating in aqueous solution, and also under the conditions of the Stevens rearrangement (with KOH powder and a small amount of methanol) dialkyl-(4-hydroxy-2-butynyl)(3-phenylallyl)ammonium bromides form dialkyl[4-(1-phenylallyl)-2,5-...
To optimize the CO2photo-reduction process, one factor at a time (OFAT) and trial-and-error optimization methods can be used30. The main disadvantage of the OFAT method is that it cannot estimate interactions and cannot explain the full effects of the parameters on the process31,32. Another...
The electron-donating effect of K in -O−K+ was transferred to the carbon ring or carbon chain through O, causing it to break at high temperatures [44], resulting in a reduction of C-OH. Figure 9. XPS O1s spectra of ACs with different KOH/BC. (a) Full spectrum, (b) AC1-700...
