Formation of the Vilsmeier-Haack complex: the performance of different levels of theory
(Springer, 2011)
Because of discrepancies in the available experimental data, an extensive theoretical investigation of the formation of the Vilsmeier-Haack (VH) complex has been carried out. The barriers to complex formation calculated ...
The effect of carbonization temperature, carbonization time and impregnation ratio on the properties of activated carbon produced from Arundo donax
(Elsevier Science Bv, 2018)
Activated carbons from Arundo donax were obtained by varying impregnation ratio, carbonization time, and carbonization temperature via chemical activation method. By operating impregnation ratio as 1.5 and carbonization ...
