Pressure was determined by measuring ruby fluorescence, according to equation P (GPa) = 248.4[(λ/λ0)7.665 − 1] (Mao et al., 1986). A BX90 DAC with an anvil culet size of 300 μm in diameter combined with resistance heating was used for the in situ high ...
The activation energy for ionic liquidcatalyzed alkylation of phenol was found to be 11.13kcal/mol in the temperature range of 50–90 ◦ C.Negative activation energy was observed for 2-tert-butylphenol (2-TBP) to 2,4-di-tert-butylphenol (2,4-DTBP) and the extended Arrhenius equation was...
The equation d[B(t)]/dt is the first derivative of [B(t)] with respect to t. It is the limit (lim) of the slope ∆[B]/ ∆t as ∆t → 0, or v=limΔt→0 v¯=limΔt→0Δ[B]Δt=Δ[B(t)]dt Alternatively, one can consider the change in concentration of the ...
