HETEROPOLYACID SALT CATALYST, PROCESS FOR PRODUCING HETEROPOLYACID SALT CATALYST AND PROCESS FOR PRODUCING ALKYL AROMATIC COMPOUND |
| 摘要 |
The present invention provides a heteropolyacid salt catalyst for use in an alkylation reaction of an aromatic compound or a transalkylation, disproportionation or isomerization reaction of an alkyl aromatic compound, which comprises a heteropolyacid salt catalyst represented by the following formula (1): H<SUB>4-m</SUB>Z<SUB>m</SUB>SiX<SUB>12</SUB>O<SUB>40</SUB> (1) wherein X represents W or Mo, Z represents (NH<SUB>4</SUB>) or an alkali metal atom, and m represents a numerical value of 0<m<4, and comprising a heteropolyacid salt crystal having an average particle diameter in the short axis of the crystal of less than 300 nm as a main component, wherein said heteropolyacid salt catalyst has an acid amount on the external surface of not less than 190 µmol per weight of a heteropolyacid salt. |
