Abstract
The invention discloses a preparation method of 1-(acetyl bromide)pyrene, belonging to the field of organic chemical synthesis. The preparation method disclosed by the invention aims at solving the technical problems that the raw materials of a traditional synthesis method are expensive and the cost is high and the treatment after reaction is complicated and the product is red; according to the preparation method disclosed by the invention, a proper phase transfer catalyst is added in the reaction and a buffer solution control quenching system is added in a reaction quenching process, the expensive AlBr3 is successfully replaced by cheap anhydrous AlCl3, and the product can be obtained directly through once recrystallization after the reaction; and therefore, the preparation method disclosed by the invention has the advantages of low cost, little pollution, simple and convenient treatment after reaction, good product color and adaptability to industrial production.
