Process for producing fluorene or its derivatives

A process for producing aromatic compounds comprises the step of carrying out a reaction between an aromatic carboxylic acid and a polyfluorobenzonitrile, thus forming an aromatic nitrile and a polyfluorobenzene. This process can produce the aromatic compounds with few problems with respect to worker safety and at a low cost when compared with conventional processes, and can convert the starting materials for the reaction into useful substances with ease and little waste and in a high yield.

Production process for aromatic compounds

There is provided a process for producing a (poly)alkylene glycol monoalkyl ether from an olefin and a (poly)alkylene glycol at a high conversion at a high selectivity. This process comprises reacting an olefin with a (poly)alkylene glycol in the presence of a crystalline metallosilicate as a catalyst.
