Catalytic Characteristics of 2-Methylnaphthalene Acidylation

Related Articles

Abstract 2-Methyl-6-acyl naphthalene is the precursor of polyester PEN. By the two Louis acid catalyst including ferric chloride and zinc chloride, the influence of the reaction time and reaction temperature on catalytic characteristics of 2-methylnaphthalene acidylation were discussed. The experimental results show that chlorideferric chloride has better catalytic effect and the yield of production is 84% at 25 ℃ and 5 hours. When the temperature is too high, it leads to a large number of byproducts, and decreases the production rate. Moreover, the reaction time has little influence on the selectivity of products. According to the experimental results, the appropriate operating conditions of synthesis target product were obtained.
