⑶ green synthesis technology of anthraquinone: 2-ethyl anthraquinone (2-EAQ) is the main raw material for the production of hydrogen peroxide by anthraquinone method. The annual production capacity of 2-EAQ in China has reached more than 100 million tons, and the actual output is nearly 8000 tons, accounting for more than 80% of the global share. Hydrogen peroxide has a wide range of applications, including medical, military, industrial and environmental. Especially in the environmental field, hydrogen peroxide is more and more widely used in industrial wastewater treatment, especially in the treatment of refractory organic wastewater. At present, the continuous pipeline reaction process technology is widely used in the industrial production method of 2-EAQ. Nearly 20 tons of waste dilute sulfuric acid are produced from 1 ton of anthraquinone products, and the organic content of dilute sulfuric acid is high, which makes it difficult to separate. The treatment pressure of waste dilute sulfuric acid in the whole anthraquinone industry is huge, facing the embarrassing situation of shutdown and operation.
Since 2014, Jiaxing Runbo Chemical Technology Co., Ltd. has organized the research and development of new green process of 2-ethyl anthraquinone, abandoned the traditional synthesis route of concentrated sulfuric acid or fuming sulfuric acid catalyst, and the production process is continuous, energy-saving and pollution-free, which is important for solving the problem of waste sulfuric acid treatment in China's anthraquinone industry and truly realizing "energy conservation, consumption reduction and pollution reduction" Reduce the production cost of enterprises and the pressure of environmental governance. The pilot technology has been completed, and the pilot conversion is pending. The patent "method of sulfonated graphene catalyst for the production of 2-alkyl anthraquinone (cn104725204a)" is applied.
