| Abstract: | Butyl acetate was synthesized from acetonitrile and butanol by one-step method. The effects of four factors on product yield were determined by orthogonal design.The optimum conditions were as follows: reaction temperature 105 ℃, reaction time 8 h, n (CH 3CN) ∶ n (C 4H 9OH)= 1∶ 1.05 , amount of catalyst 40% based on gross weight of reacting substances ,the yield of butyl acetate reached 88.6%, the purity of product was 99.5%. The structure of product was characterized by IR spectrum |
