Description
Изобретение относитс к области получени соединений, окрашивающих пластические массы в светопрочные цвета.The invention relates to the field of producing compounds that color plastics in lightfast colors.
Известен способ получени дибромхинакридоиа бромированием линейного хинакридона.A known method for the preparation of dibromoquinacrido bromination of linear quinacridone.
Предлагаемый способ получени дибромхинакридона заключаетс в одновременном окислении и бромироваиии дигидрохинакридона .The proposed method for the preparation of dibromoquinacridone consists in the simultaneous oxidation and bromination of dihydroquinacridone.
Пример. 314 вес. ч. сухого линейного дигидрохинакридона (1 моль}, загружают иа противень в герметически закрытую камеру, в которую помещают открытый сосуд, содержащий 480 вес. ч. жидкого брома (3 моль).Example. 314 weight. including dry linear dihydroquinacridone (1 mol}, load the baking sheet into a hermetically sealed chamber, in which an open vessel containing 480 parts of liquid bromine (3 mol) is placed.
Через 36 час дигидрохи акридои с поглощенным им бромом перенос т в эмалнрова ный аппарат. Наружным обогревом нагревают массу в аппарате до 100-120°С, выдерживают при этой температуре около 4 час и затем, включив вакуум, удал ют не вошедший в реакцию бром и большую часть образовавшегос бромистого водорода.After 36 hours, the dihydrochi acridoi with the bromine absorbed by it are transferred to an enamel apparatus. Externally heated, the mass in the apparatus is heated to 100-120 ° C, kept at this temperature for about 4 hours and then, switching on the vacuum, the unreacted bromine and most of the hydrogen bromide formed are removed.
По охлаждении массу перенос т на водныйAfter cooling, the mass is transferred to water.
раствор щелочного агента (например соды), перемешивают около часа (реакци должна быть слабощелочной), отфильтровывают фиолетовый осадок, промывают и сушат. Получают около 460 вес. ч. линейного днбромхинакри .т,она. по анализу содержание го около 340/0 брома.alkaline agent solution (e.g. soda), stirred for about an hour (the reaction should be slightly alkaline), the violet precipitate is filtered off, washed and dried. Get about 460 weight. h. linear dnbromhinakri. t, she. According to the analysis, the content of go is about 340/0 bromine.
Линейный дибромхинакридон обычным методом перевод т в одну нз выпускаемых форм пигмента. Полученный рко-окрашенный фиолетовый порошок окрашивает р д пластических масс в светопрочный чистый фиолетовый цвет.Linear dibrominacridone is converted into a single one in the produced pigment forms. The resulting brightly-colored violet powder stains a range of plastics in a light-resistant pure violet color.
Предмет изобретени Subject invention
Способ получени лииейного дибромхинакрндона , о т л и ч а ю щ и и с тем, что, с целью получени красител нластпческих масс, дающего более чистые оттенки, лине1 ный дигидрохииакридои подвергают одновременному взаимодействию с бромом и кислородом воздуха .The method of obtaining the linear dibromhinacrndone, which is so that, in order to obtain a dye of nlastpichnyh masses, giving more pure shades, the linear dihydrochloride and acridium are subjected to simultaneous interaction with bromine and oxygen.
