Description
Изобретение относитс к области получени красителей дл изготовлени кремов дл обуви, типографических красок и других, в частности нигрозина жирорастворимого.The invention relates to the field of making dyes for making creams for shoes, printing inks and others, in particular, nigrosine, which is fat soluble.
Известен способ получени красител -нигрозина жирорастворимого путем взаимодействи суспензии нигрозина спирторастворимого с водным раствором соды при 110-116°С и давление 2 атм при непрерывном размешивании реакционной массы в течение 6-10 ч с последующим выделением целевого продукта путем фильтрации реакционной массы, промывки осадка гор чей водой и сушки при температуре не выше 90°С до остаточной влажности 5%.A known method for producing nigrosine dye, fat soluble, by reacting a suspension of nigrosine alcohol soluble with an aqueous solution of soda at 110-116 ° C and a pressure of 2 atm with continuous stirring of the reaction mass for 6-10 hours, followed by separation of the desired product by filtering the reaction mass, washing the precipitate mountains whose water and drying at a temperature not exceeding 90 ° C to a residual moisture content of 5%.
Способ характеризуетс низкой производительностью и сложностью проведени процесса , св занной с высокими температурой и давлением .The method is characterized by low productivity and complexity of the process associated with high temperature and pressure.
Предлагаетс проводить процесс взаимодействи реагентов при непрерывном облучени-и ультразвуком частотою 18-24 кгц в течение 5-20 мин в сосуде из эластичного материала. Это позвол ет исключить из процесса высокие температуру и давление и получать целевой продукт высокого качества.It is proposed to carry out the process of reacting the reactants with continuous irradiation and ultrasound at a frequency of 18–24 kHz for 5–20 min in a vessel of elastic material. This makes it possible to eliminate high temperatures and pressures from the process and to obtain a high-quality target product.
138 мл воды и 51 г нигрозина спирторастворимого (в пересчете на сухой). Содержимое мешочка перемешивают так, чтобы получилась равномерна суспензи нигрозина спирторастворимого в водном содовом растворе. Загруженный пакет помешают в ванну ультразвукового генератора и подвергают действию ультразвука с частотой 18-24 кгц в течение 5- 20 мин.138 ml of water and 51 g of alcohol-soluble nigrosine (in terms of dry). The contents of the bag are mixed so that a uniform suspension of nigrosine alcohol soluble in aqueous soda solution is obtained. The loaded bag will be placed in an ultrasonic generator bath and subjected to ultrasound at a frequency of 18–24 kHz for 5–20 minutes.
После облучени содержимое пакета отфильтровывают , промывают гор чей водой и сушат при температуре не выше 90°С.After irradiation, the contents of the bag are filtered, washed with hot water and dried at a temperature not higher than 90 ° C.
