Preparation method and application of 2, 3, 5, 6-tetraaminobenzoquinone

The invention discloses a preparation method and application of 2, 3, 5, 6-tetraaminobenzoquinone, and relates to the field of organic small molecule synthesis, and the preparation method comprises the following steps: (1) at normal temperature, adding a certain amount of ammonia water into a reaction container in advance; (2) slowly adding tetrahalobenzoquinone into a reaction system in the step (1), and pre-reacting at normal temperature for a period of time; then heating the reaction system, and continuing the reaction for a period of time to fully carry out the reaction; (3) after the reaction is completed, cooling and standing to room temperature; and then carrying out vacuum suction filtration, collecting filtrate, and freeze-drying to obtain a product, namely 2, 3, 5, 6-tetraaminobenzoquinone. The reaction process is simple, parameters are easy to control, energy consumption is low, poison is low, the yield is high, industrial feasibility is high, the prepared product serves as a redox additive of the
