3,5-dibromanisole is a chemical compound that is derived from both anisole and dibromobenzenes .
presentation
3,5-dibromanisole can be prepared from 3,5-dibromophenol by methylation with dimethyl sulfate .
properties
In contrast to the corresponding phenol, the nitration of 3,5-dibromanisole takes place only twice at positions 2 and 4; 3,5-dibromo-2,4-dinitroanisole is formed, which is converted into 3,5-dibromo-2, by ether cleavage. 4-dinitrophenol (melting point 146-147 ° C) can be converted.
The flash point of 3,5-dibromanisole is above 110 ° C.
