Description
【請求項１】 互いにつながっているマクロポアとマクロポアの壁内に平均径が1 〜1,000 m のメソポアを有する連続気泡構造を有し、全細孔容積が1 〜50ml/gであり、陽イオン交換基が均一に分布され、陽イオン交換容量が0.5mg 当量/g乾燥多孔質体以上の多孔質イオン交換体からなることを特徴とする固体酸触媒。 1. An interconnected macropore and an open cell structure having a mesopore having an average diameter of 1 to 1,000 m in a wall of the macropore, a total pore volume of 1 to 50 ml / g, and cation exchange A solid acid catalyst comprising a porous ion exchanger in which groups are uniformly distributed and a cation exchange capacity is 0.5 mg equivalent / g or more of a dry porous body.
すなわち、本発明は、互いにつながっているマクロポアとマクロポアの壁内に平均径が1 〜1,000 メソポアを有する連続気泡構造を有し、全細孔容積が1 〜50ml/gであり、陽イオン交換基が均一に分布され、陽イオン交換容量が0.5mg 当量/g乾燥多孔質体以上の多孔質イオン交換体からなることを特徴とする固体酸触媒を提供するものである。 That is, the present invention has an interconnected macropore and an open cell structure having an average diameter of 1 to 1,000 mesopores in the wall of the macropore, a total pore volume of 1 to 50 ml / g, and a cation exchange group. Is uniformly distributed, and the solid acid catalyst comprises a porous ion exchanger having a cation exchange capacity of 0.5 mg equivalent / g or more of a dry porous body or more.
本発明の固体酸触媒を構成する多孔質イオン交換体は、イオン交換基が均一に分布され、0.5mg 当量/g乾燥多孔質体以上、好ましくは2.0mg 当量/g乾燥多孔質体以上のイオン交換容量を有しているものである。イオン交換容量が0.5mg 当量/g乾燥多孔質体未満であると、触媒活性が低下してしまうため好ましくない。また、イオン交換基の分布が不均一であると、反応にばらつきが生じ、反応率が低下したり、反応時間の延長が必要となるため好ましくない。なお、ここで言う「イオン交換基が多孔質体に均一に分布された」とは、イオン交換基の分布がオーダーで均一であることを言う。イオン交換基の分布状況は、ＥＰＭＡやＳＩＭＳ等を用いることで、簡単に確認することができる。多孔質体に導入するイオン交換基としては、スルホン酸基、カルボキシル基、イミノジ酢酸基、リン酸基等の陽イオン交換基が挙げられる。 The porous ion exchanger constituting the solid acid catalyst of the present invention, the ion exchange groups are uniformly distributed, 0.5 mg equivalent / g dry porous body or more, preferably 2.0 mg equivalent / g dry porous body or more Having an ion exchange capacity of If the ion exchange capacity is less than 0.5 mg equivalent / g dry porous material, the catalytic activity is undesirably reduced. In addition, if the distribution of the ion exchange groups is not uniform, the reaction varies, and the reaction rate is reduced and the reaction time needs to be extended, which is not preferable. Here, “the ion-exchange groups are uniformly distributed in the porous body” means that the distribution of the ion-exchange groups is uniform in order. The distribution state of the ion exchange groups can be easily confirmed by using EPMA, SIMS, or the like. Examples of the ion exchange group to be introduced into the porous body include cation exchange groups such as a sulfonic acid group, a carboxyl group, an iminodiacetic acid group, and a phosphate group.
