After holding the white aluminium hydroxide precipitate for 0.5 h, it was filtered and washed with distilled water. The precipitate was then added to 250 ml of ethanol in a three-neck flask with stirring at high speed for 0.5 h. Subsequently, 10 mg of CoII TPP dissolved in absolute ethanol was slowly added into the above suspension, and the mixture was heated to 50¡æ with rapid stirring for 5 h. The pink suspension was filtered and washed with bulk distilled water and the pink cake was dried at 0.10 MPa and 170¡æ for 5.5 h. As a result, 14.9 g of the pink-supported catalyst, CoII TPP/BM, was obtained. The amount of CoII TPP supported per gram of boehmite was 9.53 *10-7 mol,ÎÒÎÊһϸßÊÖ£¬Õâ¸öʵÑé¹ý³ÌÖÐÖÆ±¸ÍêÇâÑõ»¯ÂÁ£¬½«ÐÂÖÆµÄÇâÑõ»¯ÂÁ¼ÓÈëµ½ÎÞË®ÒÒ´¼ÖÐÕâ¸ö¹ý³ÌÊÇÓ¦¸ÃÎÞË®»¹ÊÇÓÐË®°¡£¿Èç¹ûÊÇÎÞË®ÊdzéÂËÍ꣬¸ÉÔïÂð£¿ÎÒ¾õµÃµ¥´¿µÄ¸ÉÔ¿ÉÄÜÇâÑõ»¯ÂÁ½ºÌå»îÐÔÊDz»ÊÇ»áϽµ£¿ |
