邻苯二腈

其选择性大于70‰。邻苯二甲腈和邻苯二甲酰亚胺的重量收率大于90‰，添加P2O5的P型催化剂表现出了好的活性和选择性。

The selectivity is > 70 % phthalonitrile and phthalimide with > 90 % weight yield The P-catalyst containing P_2 O_5 shows good activity and selectivity .

这个增强的效应归因于邻苯二甲腈基团的引入。

This enhanced response may be ascribed to the introduction of phthalonitrile core .

Synthesis of 4 - tert - Butyl Phthalonitrile

目的：为了筛选4，5-二溴-3，6-二异辛基邻苯二甲腈最佳合成工艺。

Objective : To select the optimal synthetical technology of4,5-Dibromo-3,6-Diisooctyl phthalonitrile ( molecule fragments ) .

制备了2种邻苯二甲腈负载的硅胶和7种酞菁负载的硅胶，进行了元素分析、红外吸收光谱、紫外可见漫反射光谱、比表面积和热分析等表征。

Two phthalonitrile-bonded and seven phthalocyanine-bonded silica gel were prepared and characterized by element analysis , IR , UV / vis , specific area , and thermal analysis .

结果表明，以邻苯二甲腈衍生物为前驱体的合成路线与原先采用的一锅煮法和二酸缩合法相比，具有重现性好，收率高（~80%）的优点。

It is found that their yields and reproducibility from the phthalonitrile derivatives are relative higher than either of a ' one pot ' method or from P and S group substituted phthalic acids .
