| | Dibenzylamine Usage And Synthesis |
| 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. | | Synthesis Reference(s) | Tetrahedron Letters, 26, p. 4633, 1985 DOI: 10.1016/S0040-4039(00)98771-9
