Examples of the organic solvent include saturated hydrocarbons, aromatic hydrocarbons, alicyclic hydrocarbons, and halogen-substituted products thereof.

If the amount of component B) is less than 1/3 mole per 1 mole of component (A), the production of heavy components and reactants between components (A) will increase, resulting in the reduction of the target dialkyl aromatic hydrocarbon. Yield will be poor. On the other hand, if the amount exceeds 2 moles, a large amount of mono-bodies (monoaralkyl aromatic hydrocarbons) will be produced as a by-product, resulting in a low yield of the target product, which is not preferable. The most preferable amount of component (A) and component (B) to be charged is in the range of 1/2 to 1 mole of component B) per 1 mole of component (A). The amount of catalyst used varies depending on the type of reaction raw materials, reaction temperature, pressure, and other conditions, but usually the amount of heteropolyacids in the catalyst is 0.2% by weight or more based on the total reactants, preferably 1 to 1% by weight. It is 10% by weight. If the amount of heteropolyacids is less than 0.2% by weight, the reaction rate will be low and the reaction will take a long time, and the yield of the target product will decrease, which is undesirable.On the other hand, even if the amount of catalyst is increased, the reaction will not proceed. However, from the economical point of view, it is used within 10% by weight.
