Three peptide alcohols and four peptidyl N-akyl-amides were prepared by a series-connection procedure consisting of n-1 sequencial assembly on solid support followed by ammonolysis with glycinol, benzylamine or n-butylamine, and successive extractionelution through C-18 layer. All products were obtained from this procedure without further purification, in an overall yield of 75-86%.

Literature data dedicated to formation of 4-phenylphthalonitrile were analyzed and generalized. As a result of the own studies, it has been established that on V–Sb–Bi–Zr/γ-Al2O3-oxide catalyst ammoxidation gives 83.10 mol.% 4-phenylphthalonitrile at high conversion of the initial 4-phenyl-o-xylene in a single process. In connection with increased demand to purity of 4-phe-nylphthalonitrile at using and division problem of hard-separable impurity of crystal 4-phe-nylphthalimide, a variant of the technological process design with average conversion and recirculation of the unreacted 4-phenyl-o-xylene and intermediate 4-phenyl-o-tolunitrile was proposed. In contrast to the single process, it has been determined that recirculation reduces quantity of form by-products, fractions of deep oxidation and increases selectivity on 4-phenylphthalonitrile up to 96.14% - 97.72%. For the data analysis and visualization of results it is developed and offered the software package of OptimMe written in C#.

论述了一种新型的磁性聚丙烯酸甲酯微球的制备方法,该方法制备的微球具有良好的磁性和单分散性,并且将其在磁性免疫分析技术中得以运用。首先用化学共沉淀法制备Fe3O4纳米颗粒,PMA种子颗粒由细乳液聚合方法合成,最后用单体溶胀聚合方法合成磁性PMA微球,也就是将PMA种子微球溶解于丙烯酸甲酯磁性流体中。利用氨解反应将氨基偶联在磁性PMA微球表面,进而将HCV抗体通过戊二醛共价偶联到磁性PMA微球表面。微球的单分散性、粒度分布、磁特性分别由扫描电镜、振动试样磁力计测定。实验结果表明:PMA磁性微球的平均尺寸为5.416μm,饱和磁化强度为5.839 Am2/kg,PMA磁性微球上的氨基和HCV抗体偶联量分别由原子吸收光谱仪以及紫外分光光度计测定,测定的氨基浓度为0.659 mmol/g。

On the basis of kinetic data of 4-phenyl-o-xylene and 4-phenyl-o-tolunitrile ammoxidation, formation mechanism of the products was analyzed and generalized. It has been shown that dissociative adsorption of a substrate and mononitrile occurs on the centers with high heats of adsorption of oxygen and as a consequence, completely covered with it, competitive adsorption of NH3 and O2 occurs on the centers with low heats of adsorption of the latter;mononitrile and dinitrile are formed correspondingly from adsorbed fragments of both substrate and NH3, and tolunitrile and NH3;surface interaction of adsorbed fragments of substrate and O2 with low heat of adsorption gives imide and CO2;hydrolysis of dinitrile into imide occurs on centers completely covered with ammonia;imide decarboxylation occurs on the centers covered with it;oxidative destruction of tolunitrile occurs on centers covered with substrate and mononitrile.
