| titleOfInvention |
Heteropolyacid salt catalyst, process for producing heteropolyacid salt catalyst and process for producing alkyl aromatic compound |
| abstract |
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): H4-mZmSiX12O40 (1) wherein X represents W or Mo, Z represents (NH4) 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 [mu]mol per weight of a heteropolyacid salt. |
