原始语种摘要: Abstract(#br)In this article, the composite switchable water was prepared with hydrophobic tertiary amine and switchable water, which provides a new method for washing oil sands. Firstly, pH and 1 HNMR were used to demonstrate that N,N- diethylethanolamine (DEEA) with the excellent CO 2 response could be treated as potential switchable water. In addition, N,N- dimethylaniline (DMA) was chosen as a suitable hydrophobic tertiary amine, because DMA is a more steady molecular state than DEEA at the same pH. Then, the composite switchable water (DMA + DEEA(aq)) was prepared with DMA and DEEA solutions. There was the possible presence of inductive effect between DMA and DEEA detected by 1 HNRM and it was also found that DEEA reduced the surface tension. Next, the CO 2 -triggered switchable...
