Use of ultra-low sodium silica-aluminas in the alkylation of aromatics |
摘要 |
Silica-aluminas having a sodium content less than about 0.1 weight percent show increased stability when used as a catalyst for the alkylation of aromatic compounds. Where such silica-aluminas are used as the catalyst in detergent alkylation their increased stability permits continuous alkylation to be performed at lower temperatures, as a result of which the detergent alkylate product shows an incrementally higher linearity. Fluorided silica-aluminas having a sodium content of under 0.05 weight percent are particularly advantageous. |
