摘 要:以二聚環(huán)戊二烯(dicyclopentadiene)為原料,將其裂解得到環(huán)戊二烯(cyclopentadiene,Cp);在二乙胺存在的條件下將其與四氯化鈦反應,合成了二氯二茂鈦(titanocene dichloride,TDC),并以合成的目標產(chǎn)物作為丁苯嵌段共聚物(SBS)加氫催化劑,對其催化性能進(jìn)行了研究。當加氫反應溫度為70℃,壓力為2.0 MPa,催化劑用量為0.4 mmol /100 g聚合物時(shí),SBS中加氫度達到94.2%。說(shuō)明目標產(chǎn)物具有良好的催化性能。 |

Abstract:Titanocene dichloride (TDC) was synthesized from cyclopentadiene(which was decomposed from dicyclopentadiene) and TiCl4 under the conditions such as reaction temperature 65~68℃ and time 4. The yield of TDC was 74.1%. And meanwhile the hydrogenation activity of the product titanocene dichloride for SBS was evaluated. Results showed that the hydrogenation efficiency reached 94.2% when 0.4 mmol TDC/100 g SBS was added into SBS hydrogenation system at 70°C and 2.0 MPa. |
