物の収率が低い。However, in the case of Friedel-Crafts reaction, a large amount of high-boiling compounds are generally produced as by-products, so that the target alkyl-substituted aromatic compound cannot be obtained in good yield. On the other hand, when using a gas phase reaction using a solid silica alumina catalyst, high temperatures are required and various side reactions occur, so the yield of the target product is similarly low.
