。The acid strength of the super strong acid obtained by mixing fluorosulfonic acid and antimony 5-fluoride is more than 1,00 times that of 100% sulfuric acid, which is why it cannot be used with conventional sulfuric acid or polyphosphoric acid. This makes it possible to react in a certain way. This is because various cations exist stably in super strong acids]7

にある。A feature of the present invention is that the addition ratio of antimony 5-fluoride is increased to increase the acid strength of the reaction solution, and by carrying out the reaction, it is possible to fluoresce compounds that have not conventionally reacted. The reason is that it allows insertion of a sulfonyl group.

ライドが分離される。- When alkylbenzene is gradually added to a mixture of fluorosulfonic acid and 5-antimony fluoride in a carbon oxide atmosphere, the sulfonation reaction and carbonylation reaction proceed easily. The molar ratio of the raw materials and catalyst used in the reaction is alkylbenzene:fluorosulfonic acid:5-antimony fluoride-[0.05-0.4:1:[0.5-0.4].
The molar ratio of 5-antimony fluoride should be at least 0.5 times that of fluorosulfonic acid. The reaction temperature is preferably about 20 to 60°C. After the reaction mixture is transferred to ice water, the desired formylalkylbenzenesulfonyl fluoride is separated by benzene extraction.
