Web5 was set as 1.0 and the molar ratio of [PO]/[CO 2] was 1/2. Of surprise, the combination of TEA and TEB, a quite simple Lewis pair exhibited a moderate activity for CO 2 /PO copolymerization. The conversion of PO was 54 % within 1 h at 60oC, and hence TOF was calculated to be 54 h-1 (entry 1, Table 1).Especially, a fully alternating PPC Webトリエチルアミン (Triethylamine)は、 第三級アミン に属する 有機化合物 の一種。 頭文字をとってTEAとも呼ばれる。 性状 [ 編集] トリエチルアミンは、常温では強アンモニア …
