摘 要:以沸程為140~196℃乙烯副產(chǎn)C9餾分為原料,探討了自由基聚合和Lewis酸為催化劑的催化聚合兩段聚合法,制備C9芳烴溶劑油的工藝條件,以及白土精制C9芳烴溶劑油的精制條件。結果表明:采用自由基和陽(yáng)離子催化兩段聚合,在引發(fā)劑用量為0.01%、催化劑為1.5%、反應時(shí)間4.5 h(自由基聚合1.0 h,催化聚合3.5 h)、反應溫度60℃的條件下,C9芳烴溶劑油的收率可達到70%以上;在白土用量為4%、精制時(shí)間為30 min、精制溫度為50℃的精制條件下,精制后C9芳烴溶劑油的色度較佳。 |
關(guān)鍵詞:C9餾分;芳烴溶劑油;白土精制 |

Abstract:Preparation of C9 aromatic solvent oil and its purification with clay were studied. The C9 fraction from ethylene production with the boiling point range of 140~196℃ was used as the starting material and free radical polymerization and Lewis acid catalytic polymerization were applied. Results showed that under optimum conditions the solvent oil was obtained in over 70% yield with the best whiteness value. |
Key words:C9 fraction;aromatic solvent oil;clay refining |
