Claims (11)

1. Способ совершенствования процесса получения чистого продукта из сырого антрацена, отличающийся тем, что дистилляцию проводят в две ступени, на первой ступени в качестве головного продукта отделяют фракцию с пределами кипения 280-320oС при нормальном давлении, к кубовому остатку подводят карбазольные остатки и эту смесь разделяют на второй колонне на антраценовую и карбазольную фракции.1. A method for improving the process of obtaining a pure product from crude anthracene, characterized in that the distillation is carried out in two stages, in the first stage, a fraction with a boiling point of 280-320 o C at normal pressure is separated as the head product, carbazole residues are brought to the still residue and this mixture is separated on the second column into anthracene and carbazole fractions. 2. Способ по п.1, отличающийся тем, что часть кубового остатка второй колонны отводят и снова подают в колонну. 2. The method according to claim 1, characterized in that part of the bottom residue of the second column is withdrawn and fed back to the column. 3.

The method according to claim 6, characterized in that the obtained fractions containing anthracene, carbazole, phenanthrene and fluorene are subjected to treatment by crystallization from a solvent. 8. Способ по пп.1-7, отличающийся тем, что полученный антрацен окисляют до антрахинона. 8. The method according to claims 1 to 7, characterized in that the obtained anthracene is oxidized to anthraquinone. 9. Состав чистого антраценового продукта, полученного путем обработки сырого антрацена, по пп.1-8, содержащий менее, чем примерно 60 ppm дифениленоксида. 9. The composition of the pure anthracene product obtained by processing crude anthracene according to claims 1 to 8, containing less than about 60 ppm of diphenylene oxide. 10.
