4.2.4. Optimization This procedure makes it possible to determine the combination of experimental factors that simultaneously optimizes several responses. The isoresponses obtained with Eqs. (8) and (9) are superimposed in the same graph (Fig. 9). Fig. 9 shows that the choice of coordinates for the factors to obtain a maximum yield implies a decrease in selectivity. A compromise must be found to choose the optimal area which has a practical and economic interest. Therefore, an optimal experimental domain (the striped oval) can be defined in which the best selectivity is observed from 6.5‰ to 7‰ with a satisfactory yield between 95% and 97%. The experimental conditions are determined: the cyclohexane content, x, is about 40% and the solution/solvent ratio, w, is about 30%. [ Last edited by 豫讓 on 2011-12-4 at 13:21 ] |

4.2.4優(yōu)化 這一過程給人們確定實驗因素的組合帶來可能性,同時也會優(yōu)化幾個反應(yīng)。由方程8和方程9得到的結(jié)果在圖9當中是疊加的。圖9顯示:選擇實驗因素的坐標來獲得最大值就意味著選擇性的降低。人們需要找到一個折中的方案以選擇最佳區(qū)域,來獲得實用的經(jīng)濟利益。因此,我們可以確定一個最佳的實驗范圍,在此范圍內(nèi),最好的選擇性是從6.5‰到7‰,同時可以得到一個令人滿意的最大值區(qū)域:95%至97%。實驗條件是確定的:環(huán)己烷含量x大約是40%,溶液溶劑之比w大約是30%。 |
