Adding a certain compound to certain chemical reactions, such as: 150-78-7, name is 1,4-Dimethoxybenzene, belongs to ethers-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 150-78-7, HPLC of Formula: C8H10O2
In a 250 ml reaction flask, 20.0 g (0.145 mol, 1.0 eq) of hydroquinone dimethyl ether and 55 ml of glacial acetic acid were added and dissolved by ultrasonic; A solution of 15 ml of Br2 (0.290 mol, 2.0 eq) and 15 ml of glacial acetic acid was added dropwise at room temperature. After 1.5 hours, the mixture was stirred at room temperature for 2.5 h. Placed in the upper refrigerator to 10 below the temperature (not to acetic acid curing) filter; and petroleum ether washing filter cake to give a white solid, vacuum drying and then weight 35.6g, the yield of 83.6%.
