Abstract

Спосіб очищення крезилової кислоти шляхом видалення метоксиароматичних домішок за допомогою піролізу парової фази. Потік випареної сировини пропускають через нагрітий до 450-б25°С реактор, різко охолоджують продукти піролізу, видаляють неконденсовані газоподібні сполуки з охолодженого потоку і виділяють з цього потоку крезилову кислоту. Цей винахід належить до технологій видалення алкоксиароматичних домішок.
