  • Coal Tar and its Distillation Processes – IspatGuru

    Dec 26, 2018· Fractional distillation process is used for the distillation of coal tar. Fractional distillation of tar refers to the process by which components in a chemical mixture are separated by taking advantage of the difference in their boiling points. Distillation of coal tar is carried out mainly to produce benzols, naphtha, creosotes, naphthalene, anthracene, carbolic and cresylic acids, pyridine and pitch.Онлайн-запрос
