A new method of synthesizing 1,4-dimethoxybenzene(cas 150-78-7): This process uses the resulting product does not contain unreacted hydroxyl anisole and hydroquinone and other impurities completely, product quality is better than the original process, purification can be achieved without superior grade requirements; this process compared with the original closing process rate increase of about 5%, and the amount of dimethyl sulfate save more than 40%, with considerable economic value; after this test distillation not only increase yield but also eliminating the traditional process of a complex series of post-processing, both simplify the process and reduce investment, but also saves time recrystallized that spent a lot of ethanol before, is a safe and feasible new synthetic route.

The new phenol resin is composed of terephthalic methanol or 1,4-dimethoxybenzene(cas 150-78-7) and phenol condensation in the present of catalyst. Red-brown solid, the proportion of 1.6-1.7, a softening point of 65 ℃ -105 ℃, soluble in ethanol, acetone and other organic solvents.
