The synthetic raw materials for 1,3,5-tribromobenzene mainly include benzene, nitrobenzene, aniline, bromine water, ethanol, hypophosphorous acid, sulfuric acid, nitric acid, etc. These raw materials play different roles in the synthesis process, working together to ultimately synthesize 1,3,5-tribrobenzene.
Benzene: As a starting material, nitrobenzene is obtained through nitration reaction.
Nitrobenzene: Aniline is obtained through catalytic reduction reaction.
Aniline: Reacts with bromine water to obtain 2,4,6-tribromoaniline.
Bromine water: used for reacting with aniline to produce 2,4,6-tribromoaniline.
Ethanol and hypophosphorous acid: used to reduce 2,4,6-tribromoaniline to 1,3,5-tribromobenzene.
Sulfuric acid and nitric acid: may be used to initiate or promote specific chemical reactions during the synthesis process.
The process of synthesizing 1,3,5-tribromobenzene involves multiple steps, including nitration, reduction, halogenation, and other reactions. These reactions require specific conditions and catalysts to ensure efficient and selective synthesis of the target compound. In addition, the synthesis process may also involve some special chemical treatments, such as diazotization, sulfonation, etc., to achieve the strategy of "borrowing the east wind", that is, to promote the reaction by introducing and removing specific functional groups.
The final synthesized 1,3,5-tribromobenzene is a light yellow brown powder that is insoluble in water but soluble in hot ethanol and glacial acetic acid. Its physical and chemical properties determine its applicability in specific applications, such as as as a solvent or for specific types of chemical reactions.
