| Abstract：The synthesis of n-butyl acrylate from acrylic acid and n-butyl alcohol in the presence of a novel solid catalyst was studied .The yield of n-butyl drylate was 98.1%.The purity of product may exceed 99% by reducetng pressure distillation. The factors effecting the yield of the product and the optimum reaction conditions were offered. |
| Key words：acrylic acid; solid catalyst; n-butyl acrylate; catalytic esterification |
