Product Application of Dibutylamine CAS#111-92-2

Synthetic intermediate. Used in the production of dyes, rubber vulcanization accelerators, corrosion inhibitors, drugs, and oil additives. This product is toxic, with an oral LD50 of 550 mg/kg for mice. Dibutylamine is used to produce dithiocarbamate accelerators. For example, zinc dibutyl dithiocarbamate (accelerator BZ) is obtained by substitution of accelerator TP with ZnCI2. And accelerator TP (sodium dibutyl dithiocarbamate) is obtained by the reaction of dibutylamine with carbon disulfide and sodium hydroxide. This type of product is a super accelerator, and is generally used in latex production because of its short scorch time. Accelerator TP reacts with NiSO4 to obtain antioxidant NBC. This product protects natural rubber, styrene-butadiene, chloroprene and other synthetic rubbers from heat, ozone, and weather aging. Dibutyl dithiocarbamate (molybdenum, lead, antimony), such as dibutyl lead. Used as a petroleum additive, it has the functions of anti-oxidation, anti-wear, and anti-extreme pressure. Accelerator TP is oxidized with oxidant potassium ferrocyanide at a temperature below 0°C to generate tetrabutylthiuram disulfide. It is also a super accelerator for natural rubber and synthetic rubber, and can also be used as a vulcanizing agent.
