  • Solubility: Insoluble in water, soluble in anhydrous ethanol, benzene, kerosene, dichloromethane, chloroform, petroleum ether, isopropyl alcohol and hot ether.
• Chemical Properties
  It is alkaline and can react with acids to form salts. It is stable under normal temperature and pressure, but should be kept away from oxidants, moisture and acids.
• Uses
  • Intermediate: It is an intermediate for the preparation of antistatic agents, softeners, surfactants, bactericides, corrosion inhibitors, metal extractants and hydraulic fluids.
  • Dye Manufacturing: It can be used as a precursor for some dyes, and is often used in the production of yellow and orange pigments in the printing and dyeing industry.
  • Plastic and Artificial Leather Field: It can be used as a softener and stabilizer for plastic artificial leather.
  • Preservative: It can be used as a preservative for metal materials (such as aluminum and copper).
  • Paint Additive: It can be used as an additive in oil paints, which can accelerate the drying of the paint and make it more wear - resistant and corrosion - resistant.
  • Rubber Accelerator: By increasing the number of polar groups in the rubber molecule and the cross - linking effect on the rubber, it can make the rubber have better mechanical properties at high temperature.
• Synthesis Method
  It can be synthesized from 1 - bromooctane and 5 - methyl - 1,3,4 - thiadiazol - 2 - amine, or from octylamine. It can also be prepared by heating chloro - octane and ammonia in ethanol, or by the reaction of octanol and ammonia under the catalysis of aluminum oxide - carbon, and then refined to obtain dioctylamine. The refining method usually includes dehydration with sodium metal followed by distillation.
• Safety Information
  It belongs to dangerous goods, and the dangerous goods marks are C (Corrosive), N (Dangerous for the environment), Xi (Irritant). The dangerous class code is 22 - 34 - 50/53 - 36/37/38, and the safety instructions are S26 - S36/37/39 - S45 - S60 - S61 - S29 - S36. It should be stored in a cool, ventilated, dry and dark - proof place, and the storage container should be made of materials with good corrosion - resistance and tight - sealing performance.
