化學(xué)的特性
1,4-dibromobenzene is a dibromobenzene. It is a white or off-white powder. freely soluble in hot ethanol, acetone, ether and hot benzene, soluble in ethanol and benzene, insoluble in water. It has a strong smell similar to that of the lighter chlorine analogue. It can be used as a precursor to the dye 6,6-Dibromoindigo.
使用
1,4-Dibromobenzene is used in the synthesis of 2,5-dibromoacetophenone, triarylamines and trans- stilbenes. It is widely used as a heavy liquid solvent as well as a motor oil additive. It finds application as an intermediate in the manufacture of organic chemicals such as dyes, pharmaceuticals and flame retardants for polymeric materials.
