Description

Technical Field

[0001] This utility model relates to the field of copper di-n-butyldithiocarbamate production technology, specifically to a raw material processing reaction device for copper di-n-butyldithiocarbamate production. Background Technology

[0002] Copper di-n-butyldithiocarbamate is an important organosulfur compound with the chemical formula C18H36N2S4. Cu, with a molecular weight of 472.306 and CAS Registry Number 13927-71-4, appears as blackish-brown flaky crystals or dark brown powder. It is insoluble in water but soluble in organic solvents such as acetone and butyl acetate. Its melting point is 60-61℃. It readily decomposes in acid, releasing carbon disulfide. This compound is primarily used as a polymerization inhibitor, effectively preventing the self-polymerization of unsaturated olefin monomers such as acrylates during storage and transportation. It also acts as a stabilizer for plastic products, improving their weather resistance. Furthermore, it is used as an additive in materials such as screen printing inks. Its production uses water as the reaction medium. The core raw materials include copper oxide, dibutylamine, and carbon disulfide. The raw material processing requires first pulverizing and purifying the copper oxide to ensure purity standards are met; dibutylamine needs to be distilled to remove impurities; and carbon disulfide needs to be dried and dehydrated. The three are reacted in a reaction vessel in a specific ratio, and the resulting product is then separated, washed, and dried to obtain the final product.

[0003] Currently, when producing copper di-n-butyldithiocarbamate, a stirred reactor is required to stir the raw materials. Before the reaction, the raw materials, such as copper oxide, need to be added into the reactor through a feed pipe. However, copper oxide is in solid powder form, and during feeding, it is easy for it to adhere to the inner wall of the pipe due to its roughness. This results in residual copper oxide not participating in the reaction, reducing the utilization rate of the raw materials. Long-term residue may lead to a decrease in the inner diameter of the pipe or even blockage, affecting the subsequent feeding efficiency and hindering the production and processing of copper di-n-butyldithiocarbamate.
