Dibenzylamine Chemical Properties,Usage,Production
Chemical Properties
colorless to light yellow oily liquid with ammonia odor. soluble in ethanol and ether, insoluble in water.
Uses
Dibenzylamine is used to prepare rubber accelerator for the vulcanization process and reaction-stoppers. Dibenzylamine type accelerators reduce nitrosamine production in the compounding process. It is also used to produce dibenzyl-nitroso-amine.
Preparation
Dibenzylamine is obtained by the reaction of benzyl chloride and liquid ammonia in ethanol.
Application
Dibenzylamine is an important organic synthesis intermediate, mainly used to produce efficient and non-toxic vulcanization accelerators tetrabenzylthiuramdisulfide (TBZTD) and zinc dibenzyldithiocarbamate (ZBEC). Synthesize penicillin and curing agent for rubber and plastic curing, and can be used in the detection of cobalt, cyanate, and iron.
Definition
ChEBI: Dibenzylamine is an aromatic amine.
Biological Functions
Dibenzylamine (DBA) has anticonvulsant effects. It can block NMDA-evoked currents in a concentration and voltage-dependent manner. This conclusion was researched in an audiogenic seizure-susceptible mouse model. It possesses antiproliferative properties and could be of interest for the development of new antitumor drugs.

Hazard
Dibenzylamine is danger.
H302 (99.32%): Harmful if swallowed [Warning Acute toxicity, oral]
H314 (57.43%): Causes severe skin burns and eye damage [Danger Skin corrosion/irritation]
H315 (42.57%): Causes skin irritation [Warning Skin corrosion/irritation]
H319 (42.57%): Causes serious eye irritation [Warning Serious eye damage/eye irritation]
H412 (32.43%): Harmful to aquatic life with long lasting effects [Hazardous to the aquatic environment, long-term hazard]
Purification Methods
Purify the amine by distillation in a vacuum. It causes burns to the skin. The dihydrochloride has m 265-266o (from MeOH/HCl), and the tetraphenyl boronate has m 129-133o.
