| titleOfInvention | Method for producing diarylmethanes |
| abstract | The present invention relates to a method for producing diarylmethanes represented by the following formula (III)n wherein R¹ to R³ each stand for a hydrogen atom or an alkyl group having 1 to 3 carbon atoms. This method comprises the reaction of a benzyl chloride represented by the following general formula (I) with benzene or an alkylbenzene represented by the following general formula (II):n wherein R¹ to R³ have the same meanings as defined above. and is characterized in that the catalyst used is an HY or HL type zeolite having a SiO₂/Al₂O₃ molar ratio of 4 -10 and an alkali metal content of 5% by weight or less, calculated as an alkali metal oxide, or a zeolite obtained by the exchange of said NY or HL type zeolite with cations of a di- or tri-valent metal. |
