Figure 5.
Contour plots show the different reaction behaviors (a) reaction temperature and reaction time with a fixed ultrasonic power of 120 W; (b) reaction temperature and ultrasonic power with a fixed reaction time of 8 h; and (c) reaction time and ultrasonic power with a fixed reaction temperature of 65 °C. The numbers on the contours indicate the molar conversion of octyl cinnamate under specific reaction conditions.
