    • This invention, which belongs to the field of organic synthesis, involves “One-step synthetic method of 2,9-dimethyl-1,7-diphenyl-1,10-phenanthroline”. This method uses O-phenylenediamine and formula III to react under the condition of mixed-shrinking agent, the synthesis can be completed in one step, the stated mixed-shrinking agent is mixture of hydrochloric acid and organic acid. The organic acid serves as phase transfer catalyst and shrinking agent, meanwhile, as buffer reagent, organic acid reduces polymerization of III, and side products as well. The products gained are of high purity and the reaction is mild and easy to control. Since there is no polluting material added and generated, the waste is safe to discharge. In the after treatment of reaction, ketone solvent is used to reduce separation step and product lost, thus improving yield.
    • 属于有机合成领域的本发明涉及“2,9-二甲基-1,7-二苯基-1,10-菲咯啉的一步合成方法”。 该方法使用O-苯二胺和式III在混合收缩剂的条件下反应,合成可以一步完成,所述混合收缩剂是盐酸和有机酸的混合物。 有机酸用作相转移催化剂和收缩剂,同时作为缓冲剂,有机酸还可以降低III和侧产物的聚合。 所得产品纯度高,反应温和,易于控制。 由于没有污染物质的添加和生成,废物是安全的排放。 在反应后处理中,使用酮溶剂来减少分离步骤和产物损失,从而提高产率。

    • The present invention provides an apparatus for manufacturing semiconductor wafer comprising at least two manipulators, at least one set of chemical gas/liquid distribution unit and an air circulating and filtering unit. The air circulating and filtering unit is separated into three regions, including the front region, the middle region, and the side region, which are controlled by respective control electric motors to achieve uniform air flow and uniform pressure in the respective regions. The cleaning degree in the internal of the apparatus can be improved by the regional control of the air circulating and filtering unit; the wafer transport efficiency can be enhanced by the double-armed manipulators having multiple degrees of freedom; and the product yield per unit area can be increased by the chemical gas/liquid distribution unit providing stable and uniform gas/liquid flow and pressure.
