• Solubility: Slightly soluble in water, with a solubility of 0.35g/100ml in water; miscible with organic solvents such as ethanol, ether and acetone.

Chemical Properties

• Acidity and Alkalinity: Di-n-butylamine is a weak base and can react with acids to form salts.
• Reactivity: It can react with carboxylic acids and acid anhydrides to form amides, be oxidized to hydroxylamines, and also react with halogens, etc.

Production Method

• Ammonolysis of n-Butanol: Vapor of n-butanol and ammonia are mixed under low pressure, and the reaction is carried out at 170-200℃ using catalysts such as cobalt-alumina and molybdenum oxide to generate a mixture of three butylamines. Then, di-n-butylamine product is obtained through separation processes such as rectification.

Applications

• Pesticide Field: Used in the synthesis of pesticides such as carbosulfan.
• Rubber Industry: Can be used to synthesize rubber vulcanization accelerators (e.g., BZTP) and antioxidants (e.g., NBC).
• Other Fields: Also used in the production of POP polymerization catalysts, corrosion inhibitors, mineral flotation agents, oil additives (e.g., dibutyldithiocarbamate), and serves as an intermediate in the synthesis of pharmaceuticals, dyes, etc.

Safety Information

• Toxicity: Highly toxic. The LD₅₀ (oral, rat) is 189 mg/kg, and the LD₅₀ (oral, mouse) is 290 mg/kg.
• Hazard Classifications: Flammable liquid; Acute toxicity (oral) Category 4; Acute toxicity (inhalation) Category 1; Acute toxicity (dermal) Category 3; Skin corrosion/irritation Category 1; Serious eye damage/eye irritation Category 1; Acute aquatic toxicity Category 2.
• Protective Measures: When using, appropriate protective equipment should be worn, such as gloves, goggles and gas masks. It should be stored in a cool, dry and well-ventilated place, and kept away from oxidants and acids.

Packaging Forms of Di-n-butylamine

• Glass Bottles: Suitable for packaging small doses of di-n-butylamine. For example, the di-n-butylamine products of Merck Group are available in glass bottle packaging with specifications such as 100ml, 1L and 2.5L.
• Steel Drums: Industrial di-n-butylamine is often packaged in closed steel drums, which usually have large capacities, with common specifications of 150kg and 200kg.
• Plastic Drums or Iron Drums: Di-n-butylamine can also be contained in plastic drums or iron drums, which are also common packaging forms.
• Tank Cars: For the transportation and storage of large quantities of di-n-butylamine, tank cars are usually used for packaging.

In addition, in accordance with relevant regulations, the packaging containers of di-n-butylamine should have clear and firm marks, indicating the product name, manufacturer's name, address, production date, batch number, net weight and other information. At the same time, the "corrosive substance" mark in line with the provisions of GB 190 should also be labeled.
