Abstract

The invention discloses a preparation method of a coronene compound. The method comprises the following steps of: (1) pretreating a catalyst containing an SAPO molecular sieve; and (2) filling a reactor with a raw material containing non-cyclic olefin, and carrying out contact reaction with the catalyst pretreated in the step (1) to obtain the coronene compound, wherein the pretreatment refers toactivation of the catalyst. The method does not need expensive raw materials or complex operation, and is suitable for large-scale production.

Description

technical field [0001] The application relates to a method for preparing coronene compounds from acyclic olefins, which belongs to the field of organic chemistry. Background technique [0002] Because it can be used as a fluorescent material, the research of coronene and its derivatives has always attracted people's attention. In recent years, it has been found that coronene and its derivatives are excellent organic fluorescent materials for making UV-CCD. The maximum emission wavelength of coronene is 520nm, the maximum absorption wavelength is 255nm, and it also has high quantum efficiency. Coronene is a very ideal UV-CCD material. [0003] At present, the preparation methods about coronene mainly include the following three kinds: [0004] The first is the preparation method disclosed by Joost T.M.van Dijk in J.Org.Chem.1996,61,1136-1139, and the chemical reaction equation of the method is as follows: [0005] [0006] In this method, the temperature needs to be lo...
