【Abstract】 The basic situation of the solvent systems in anthraquinone process of the main foreign hydrogen peroxide production companies is introduced. The basic physical parameters of the currently used solvents for anthrahydroquinone are collected, treated, determined, and compared. The features of the new technology using tetrabutylurea-containing working solution developed by Liming Research & Design Institute of Chemical Industry Co., Ltd. and its application situation in the model test and the industrial plant are introduced. The new technology possesses significant advantages compared with the domestic existing technologies. The capacity can increase by 30%~50% by using the new technology for the same scale plant, and the consumption index can effectively decrease. The economic benefit is remarkable.更多还原
