Figure 4. The difference of alkylate components between H2SO4 alkylation with ChCl-Pho (1:2) as a function of temperature (a). Temperature-dependent C8components for H2SO4-catalyzed alkylation with ChCl-Pho (1:2) additive (b). Reaction conditions: ChCl-Pho (1:2) concentration 1.0 wt%, stirring rate 3000 r/min, reaction time 20 min, volume ratio of H2SO4/hydrocarbon 1.5:1, volume ratio of I/O 12:1.
