We focused the study on the synthesis methods of quinoxaline, nitration of its aromatic ring and chlorination of its heterocycle. In this paper, we thought about environmental protection, the cost of material, the feasibility of industrialization, workup easily, and obtained 2,3(1H,4H)-quinoxalinedion, 6-nitro-2,3(1H,4H)-quinoxalinedion, 6,7-dinitro-2,3(1H,4H)–quinoxalinedion, 2,3-dichlo- roquinoxaline, 6–nitro-2,3-dichloroquinoxaline,and 6,7- initro-2,3-dichloro-quinoxaline. A more reasonable, easily, efficient and simple reactive route to synthesize above-mentioned compounds was developed by systematically investigating the yield, the purity and physical character of intermediates.

Value is the product of the relationship of demand and supply between subjects and objects Subjects consist of three levels such as human totality,groups subjecting to the human totality,and human individuals Coresponding to it,objects include the outside world with respect to human totality（groups+individuals+the world outside human being）,the outside world with respect to human groups,and the outside world with respect to human individuals Therefore,things possess value,so do human beings Because humans themselves are the unity of subjects and objects,humans have selfvalue The reciprocal function of the factors constituting value decides the production of value,promote the changes of value,which is the basic subject of thelaw of value The three factors which have influence on the changes in value are the demand of subjects.the character of objects.and practice The origin of the conflicts of value concepts lies in the differences and opposites of the living conditions of human subjects The direct originis the differences and opposites of value objects Therefore,in order to gradually eliminate the conflicts of human value concepts,the differences of the living conditions of human subjects must be eliminated thoroughly

价值是主客体之间需要与满足关系的产物。主体有人类整体、人类整体之下的群体以及人类个体三个层次，与之相应，客体也包括与人类整体相对的外部世界（群体+个体+人以外的世界）、与人类群体相对的外部世界以及与人类个体相对的外部世界。因而不仅物具有价值，人亦有价值。由于人自身是主客体的统一，因而人还有自我价值。构成价值的各个要素相互作用决定价值的生成、推动价值的变化，这是价值规律的基本内容。影响价值变化的主要有主体需要、客体属性及实践三个要素。价值观念冲突的最终根源在于人类主体生存条件之差别和对立，直接根源则在于价值客体的差别和对立。因而要逐步消除人类价值观念的冲突就必须从根本上消除人类主体生存条件方面的差别做起。
