Abstract
The invention relates to a method for preparing tetraalkyl thiuram disulfide by photocatalytic oxidation. The method comprises the following steps: carrying out mixed reaction on secondary amine, carbon disulfide and a catalyst in a medium to generate an intermediate product; and carrying out catalytic oxidation reaction on the intermediate product under illumination to obtain tetraalkyl thiuram disulfide. According to the invention, the method is high in reaction speed and mild in condition, and energy conservation and efficiency improvement are achieved; the used medium and catalyst can be recycled, so that the resource utilization rate is improved; and the method does not produce inorganic salt by-products, and the product has high yield and high purity.
