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
231.6 g (1.5 mol) of 3,5-dimethoxytoluene are dissolved in 1 litre of diethylether, followed by dropwise addition, under nitrogen and at room temperature, of 1 litre of a 1.6 N solution of butyllithium (1.6 mol) in hexane. The reaction mixture is left for 18 hours at room temperature and then, after cooling to 30 C., 1 litre of diethylether is added and carbon dioxide is bubbled through for one hour, while maintaining the temperature at 30 C. The reaction mixture is taken up in 6 litres of 2 M sodium hydroxide solution, the aqueous phase is separated out after settling has taken place and is acidied with 6 N hydrochloric acid solution. The precipitate formed is ltered off, rinsed with water and dried under vacuum at 40 C. in order to obtain white crystals; m.p.=187 C.; yield=88%.
