Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 4179-19-5, name is 3,5-Dimethoxytoluene, This compound has unique chemical properties. The synthetic route is as follows., 4179-19-5
1,3-dimethoxy-5-methylbenzene (30 g, 0.20 mol) and dichloromethane (900 mL) were added to a dry round bottom flask (1 L).To the above solution, a sulfone dichloride (52.5 g, 0.40 mol) was added dropwise under ice-cooling, and the mixture was stirred and stirred at room temperature overnight.After the reaction was completed, NaHCO3 aqueous solution was added dropwise to adjust pH=8, extracted with dichloromethane, washed with dilute hydrochloric acid and distilled water, and dried.Concentration under reduced pressure gave the compound 2,4-dichloro-1,5-dimethoxy-3-methylbenzene (31 g, white solid).
