The influence of reaction temperature on CHE reaction over cobalt resinate at 7 h was investigated and shown in Fig. 1. It is seen that the conversion of CHE increased almost linearly with reaction temperature up to 333 K. The selectivity of 2-CHON also increased with increase in reaction temperature up to 333 K. A further increase in the reaction temperature resulted in the decrease in the con-version rate of CHE and the selectivity of 2-CHON, probably owing to the polymerization of CHE or 2-CHON at higher temperature. Whereas the selectivity of 2-CHOL decreased with the increase of reaction temperature up to 333 K, which is attributed to the further reaction of 2-CHOL to 2-CHON. Beyond 333 K, the selectivity of 2-CHOL increased with increase in reaction temperature. Considering the effect of temperature on both conversion of CHE and the selectivity of 2-CHON, 333 K was chosen as the suitable temperature for the oxidation of CHE. 發(fā)自小木蟲Android客戶端 |

| 我們調(diào)查了反應溫度在樹脂酸鈷存在下反應7 h對CHE反應的影響,如圖1所示?梢钥吹诫S著反應溫度的增加(直至333k)CHE的轉(zhuǎn)化率幾乎是呈直線增加的。2-CHON的選擇性也是隨著溫度增加(直至333k)而增加的。進一步提高反應溫度導致CHE的轉(zhuǎn)化率和2-CHON的選擇性降低,可能由于在更高的溫度CHE或2-CHON的聚合作用。而2-CHOL的選擇性隨反應溫度(到333 K)的增加而下降,這是由2-CHOL進一步反應為2-CHON導致。超過333k, 2-CHOL的選擇性隨著反應溫度的增加而增加。考慮溫度的影響對CHE的轉(zhuǎn)化和2-CHON的選擇性,選擇333 K為CHE的氧化的適用溫度。 |
