Abstract
The invention discloses a synthesis method of a dibenzoxazole type compound. In organic sovlent, a closed-loop condensation reaction is directly carried out between an aromatic dinitrile compound and substituted or nonsubstituted o-aminophenol hydrochloride to synthesize the dibenzoxazole compound or compounds with different substituents, and the composite proportion of the compound can be regulated according to different raw material proportionings. The method has the advantages of smooth reaction process, short reaction time, high yield rate of products, low cost, little three wastes, environmental protection, etc. and better faciliates large-scale production. The product produced by the method can be applied to the fluorescent whiting of synthesized or natural polymeric materials.
