Pure benzene is a colorless, transparent liquid with a unique aromatic odor that is miscible with alcohols, ethers, and acetone, and slightly soluble in water. The three bases under the Group (Xingtai, Tangshan, and Juye) have a total production capacity of 880,000 tons, radiating to the North and East China regions to form an overall layout. The national proportion is 11.3%, and it is in a dominant position in the crude benzene hydrogenation industry. Its pure benzene internal control standards are higher than the national standard for superior products:
