Description
В предлагаемом способе приготовлени стойких смесей щелочных солей нитрозаминов с азокомпонентами пасту щелочной соли какого-либо нитрозамина смешивают с щелочными сол ми пиразолоновых производных или ацилацетильных производных аминов, или диацил ацетильных производных диаминов, заключающих способную к азосочетаыию кислотную метиленовую группу. В результате такого приготовлени получаютс насты или, по высушивании, сухие порошки , стойкие при хранении, по растворении тотчас годные дл получени азокрасителей на волокнах.In the proposed method of preparing stable mixtures of alkali salts of nitrosamines with the azocomponents, the paste of alkaline salts of any nitrosamine is mixed with alkali salts of pyrazolone derivatives or acylacetyl derivatives of amines, or diacyl acetyl derivatives of diamines containing an acid methylene group capable of azo-combining. As a result of this preparation, we can obtain crusts or, upon drying, dry powders that are stable during storage, dissolving, and are immediately suitable for the preparation of azo dyes on fibers.
Пример 1. 32,8 части 74о/о-го 2. 5- дихлорфенилметилпиразолона размалывают в шаровой мельнице с 8,2 част ми 9Т 1о-го едкого натра и 114 част ми пасты натриевой соли нитрозамина из онитранилина (содержащей 13, основани и свободного едкого натра) в однородную массу. Получают 155 частей пасты.Example 1. 32.8 parts of 74o / oh 2. 5-dichlorophenylmethyl pyrazolone is milled in a ball mill with 8.2 parts of 9T 1-th caustic soda and 114 parts of a paste of onitraniline sodium nitrosamine (containing 13, base and free caustic soda) in a homogeneous mass. Get 155 parts of pasta.
Пример 2. 20,7 частей ранизидида ацетоуксусной кислоты хорошо размалывают в шаровой мельнице с 20,6 част ми раствора едкого натра в 43° Вё и, потом, тщательно размешивают со 114 част ми пасты натриевой соли нитрозамина из онитранилина (содержащей 13, основани и 3% свободного едкого натра). Получают 155 частей слегка коричневатой пасты.Example 2. 20.7 parts of acetic acetic acid ranisidide are ground well in a ball mill with 20.6 parts of caustic soda solution at 43 ° Be and, then, are thoroughly mixed with 114 parts of the paste nitonamine sodium nitrosamine (containing 13, bases and 3% free caustic soda). 155 parts of a slightly brown paste are obtained.
Пример 3. 38 частей диацетоацетилотолидина мелко размалывают с 16,5 част ми 97°/о-го едкого натра и, потом, хорошо смешивают с 95,3 част ми 33, пасты натриевой соли нитрозамина из З-нитро-4-толуидина, который содержит еще свободного едкого натра. Масса потом сушитс в вакууме при умеренной температуре и размалываетс в мелкий порошок.Example 3. 38 parts of diacetoacetylothotidine are finely ground with 16.5 parts of 97 ° / oh sodium hydroxide and, then, mixed well with 95.3 parts 33, pastes of sodium salt of nitrosamine 3-nitro-4-toluidine, which contains still caustic soda. The mass is then dried under vacuum at a moderate temperature and ground to a fine powder.
Пример 4. 38 частей диацетоацетилотолидина мелко размалывают с 16,5 част ми 97/о-го едкого натра и, затем, заиешивают в шаровой мельнице с 237 част ми 15 /о-ой пасты натриевой соли нитрозамина из 2.5-дихлоранилина вЬднородную массу.Example 4. 38 parts of diacetoacetylothotidine are finely milled with 16.5 parts of 97 / oh sodium hydroxide and, then, in a ball mill with 237 parts of 15 / oh paste of sodium nitrosamine salt from 2.5-dichloroaniline, a homogeneous mass.
Пример 5. 38 частей диацетоацетил - 4.4 - диаминоазобензола размалывают с указанными в примере 4 количествами едкого натра и натриевой соли 2.5-дихлорбензолнитрозамина.Example 5. 38 parts of diacetoacetyl - 4.4 - diaminoazobenzene are ground with the amounts of caustic soda and sodium salt of 2.5-dichlorobenzene nitrosamine indicated in example 4.
Пример 6. 28,1 частей ацето-ацетил-4амино азобензола размалывают в однородную пасту в шаровой мельнице с 20,6 част ми раствора едкого натра в 43° Be и 42 част ми пасты натриевой соли нитрозамина из 5-нитро-2-толуидина (содержащей 400/0 основани и сэоббднога едкого натра).Example 6. 28.1 parts of aceto-acetyl-4-amino-azobenzene are milled into a uniform paste in a ball mill with 20.6 parts of sodium hydroxide solution in 43 ° Be and 42 parts of paste of nitrosamine sodium salt from 5-nitro-2-toluidine ( containing 400/0 base and seobbnog caustic soda).
