2,3-Dimethylbromobenzene Usage And Synthesis
| Chemical Properties | Clear colourless to light yellow liquid |
| Uses | 3-Bromo-o-xylene is an important raw material and intermediate used in organic synthesis, pharmaceuticals and agrochemicals. |
| Synthesis | In a 3L four-necked flask equipped with stirring, reflux tube and thermometer, 106g (1mol) of o-xylene and 107mL (1.97mol) of 98% concentrated sulfuric acid were added, and then heated at 100?? for 1.5h with stirring, and cooled to room temperature. Add 1500mL of water and stir to dissolve, then neutralize with 473g of barium hydroxide hydrate and 750mL of water under stirring to pH 7. Filter while hot, pour the filtrate into a 3L three-mouth flask, add 192g of bromine (1.2mol), 200g of barium bromide and 700mL of water under stirring at 50~60?? and stir to react for 15h at 50~60??, then cool, filter and add 200mL of water??200g of barium bromide, and then cool and filter. Then cooled, filtered, washed with water 200mL??2, dried in vacuum, obtained 3-bromo-o-xylene sulfonic acid barium salt about 231g, yield 69%. |
