Description
В германском патенте № 360690 описан способ конденсации с ароматическими аминами продуктов действи хлористой серы на амины; эти же продукты, как известно, будучи подвергнут действию щелочей в присутствии восстановителей, ведут к образованию, по указани м германского патента № 367346, о-амино-арилмеркаптанов .German patent no. 360690 describes a method of condensation with aromatic amines of products of the action of sulfur chloride on amines; these products, as is well known, when exposed to alkalis in the presence of reducing agents, lead to the formation, according to the indications of German patent No. 367346, o-amino-aryl mercaptans.
В предлагаемом способе кубовые красители получают путем конденсации в водной, спиртовой или уксуснокислой среде изготовленных по данным вышеуказанных германских патентов 2:5 диамино - арил меркаптанов общей формулыIn the proposed method, vat dyes are obtained by condensation in an aqueous, alcoholic or acetic acid medium made according to the above German patents 2: 5 diamino - aryl mercaptans of the general formula
