【摘要】：以異丙胺為核合成了一種1.0代聚酰胺-胺型超支化大分子骨架,并進(jìn)一步與水楊醛和六水合氯化鎳通過"一鍋法"合成了一種具有新型支鏈結(jié)構(gòu)的超支化水楊醛亞胺鎳系催化劑。采用FTIR、~1H NMR和ESI-MS表征方法證明了合成產(chǎn)物的結(jié)構(gòu)與理論結(jié)構(gòu)相符。在甲基鋁氧烷為助催化劑、甲苯為溶劑的催化體系內(nèi)確定了催化乙烯齊聚的最佳反應(yīng)條件,在Al/Ni摩爾比1000、反應(yīng)溫度25℃、反應(yīng)壓力0.5MPa、反應(yīng)時(shí)間30min的條件下,催化乙烯齊聚的活性達(dá)3.8×10~5g Olig/(mol Ni·h),齊聚產(chǎn)物主要是C8及以下烯烴,含量高達(dá)99%。在相同條件下,通過對(duì)比不同骨架結(jié)構(gòu)的超支化鎳配合物,初步確定了超支化鎳配合物催化乙烯齊聚反應(yīng)體系催化性能的影響因素。
[Abstract]:A 1.0 generation polyamide-amine hyperbranched macromolecular skeleton was synthesized using isopropylamine as nucleus. Furthermore, a novel branched chain structure was synthesized with salicylaldehyde and nickel chloride hexahydrate by one-pot method. FTIR 1H NMR and ESI-MS methods were used to characterize the structure of the synthesized products. The optimum reaction conditions for ethylene oligomerization were determined under the conditions of Al / Ni molar ratio 1000, reaction temperature 25 鈩，
