Description
-Окскантрахлнон, примен емый дл синтеза прочных красителей антрах нонового р да, получаетс об.но зЕменоЯ сульфогртпп на isurpoKсйл щелочным ИЛИ известковым плавом солеЗ сС - суль 4окислоты азтрахкно а в автоклаве при высокой температтрв. -Oxcantraxlone, used to synthesize durable anthrax dyes, is obtained by refining sulfogram on isurpoxyl by alkaline OR lime saltyc anthraxide in an autoclave at high temperatures.
Однако помимо продолжительного времени, трсбугмого дл rajroro превращенг (15-30 час), выделение оч -окснантрастнона св зано, во-первых, с об зательным нагревом или разваркой реакционноЯ кассы и ее нейтрализвцией минералъноЯ кислотой , во-вторюс, с ее переосавдением или перекристаллизацией .However, in addition to a long period of time, for rajroro transformation (15-30 hours), the release of och-oxnantrastnon is associated, firstly, with the necessary heating or boiling-up of the reactionary cash and its neutralization with mineral acid, secondly, with its re-recovery or recrystallization .
Предлагаемый способ отличаетс , тем, что cd--оксиантрахинон может бнть получен автоклавным гидролизом о -сульфокислоты а трахинона или ее солей в воде или слабой минеральной кислоте при высокой температуре. Таким образом, в отличие от кислого гидролиза сульфокнслот различных ароматических производных, приводдго.эго обычно к замене сульфогруппы на водород с образованием несульфгрова ных исходных соединений (например углеводородов ), в 8ТОЖ случае ггдроллз в кислой среде ведет к образованип оксиспедй ек«1Я .The proposed method is different in that cd-hydroxyanthraquinone can be obtained by autoclave hydrolysis of o-sulfonic acid a of traquinone or its salts in water or a weak mineral acid at high temperature. Thus, in contrast to the acid hydrolysis of sulfoxlslot of various aromatic derivatives, the drive usually replaces the sulfo group with hydrogen to form non-sulphate starting compounds (for example, hydrocarbons), in the case of SHOUT in the acidic medium, hydroxypedylation of the “1H.
