邻二氰基苯的合成及精制

Synthesis and Purification of o-Dicyanobenzene

本研究表明波相法合成邻二氰基苯时，加入适量的脱水剂三氯氧化磷和溶剂以及粗产品用水代替乙醇为溶剂进行重结晶精制，可提高其产率和纯度。

This research indicated the o-dicyanobenzene was synthesized at liquid phase method by using the right amount dchydrant of phosphorous oxychloride and solvents.The synthetic product was recrystallized in water solvent instead of in ethanol solventThe above-mentioned method raised its yield and purity.
