The standard specification involves the quality control of benzene for cyclohexane raw materials, covering key indicators such as benzene content, sulfur content, thiophene content, toluene and methylcyclohexane content. The specification specifies the purity and other physical and chemical properties of benzene to ensure the suitability of benzene in cyclohexane production. It provides a standardized detection method for the production and application of benzene, which helps to ensure that the mass of benzene raw materials meets the specified standards.
