The invention is a process for refining acetonitrile product by adding salt, which belongs to the field of acetonitrile refining. An aqueous solution of potassium fluoride or potassium carbonate is added to an aqueous acetonitrile solution to carry out a phase separation, and then the concentrated organic phase is purified by distillation. With this process can be made more than 99.8% purity of acetonitrile products. The process is simple, easy to operate, low energy consumption, high purity products.
