Dicyclohexyl crown ether synthesis method

The present invention discloses a dicyclohexyl crown ether compound synthesis method, wherein a catechol compound and dichlorodiethylether are adopted as starting raw materials, cyclization is performed through a Pedersen synthesis method to generate a dibenzo-18-crown-6 ether compound, and then catalytic hydrogenation is performed to generate a dicyclohexyl-18-crown-6 ether compound. According to the present invention, the method is mainly characterized in that the heterogeneous metal catalyst is used to make the dibenzo crown ether be efficiently converted into the dicyclohexyl crown ether, the purity can achieve more than or equal to 90% only through filtration, concentration and other simple treatments on the product after the reaction, and the used heterogeneous metal catalyst has characteristics of convenient preparation, low price, and recycling.
