The conversion yield of the product ranged from 5.99% to 26.74%. Run 3, with a mass of 2 g of Cu(NO3)2•3H2O and a temperature of 40 °C, showed the lowest mass yield (5.99%). On the other hand, test 9 showed the highest product yield (26.75%) using 2 g of precursor and 80ºC. The differences are clear when comparing tests 3, 6, and 9, which used the same mass of Cu(NO3)2•3H2O (2 g) and varied the temperature by 40 ºC, 60 ºC, and 80°C. When the temperature increases from 40°C to 80°C, the yield increases by approximately 4.5 times. The model was evaluated using Analysis of Variance (ANOVA), with 95% reliability, where each interaction and the values of the terms are shown in Table .
