Description
На способ получени нерастворимы} в воде азокрасителей, состо щий в сочетании диазо-соединений, не содержащих сульфо- или карбоксильной групп, с диацето ацетильными производными диаминов типа СО. СН,. CONH XNH СО СН СО СНз, где X-простой или замещенный в дре дифениловый остаток выдан патент за № 10422.To the process of obtaining, water-soluble azo dyes, consisting in the combination of diazo compounds not containing sulfo or carboxyl groups, with diacetocetyl derivatives of diamines of the CO type. CH, CONH XNH CO CH CO CH3, where the X-simple or substituted diphenyl residue in the nucleus has been granted patent No. 10422.
Предлагаемое видоизменение этого способа заключаетс в том, что дис13о-соединени , не содержащие сульфо- или карбоксильной групп, сочетают, вместо диацето-ацетильных производных диамино-диарилов, с другими аналогичными ди-ацилацетильными прои рдными тех же диамино-диарилов. такого рода производные могут быть приготовленыThe proposed modification of this method consists in the fact that dis13o-compounds that do not contain sulfo or carboxyl groups combine, instead of diaceto-acetyl derivatives of diamino-diaryls, with other similar di-acetyltyl derivatives of the same diamino-diaryl. these kind of derivatives can be cooked
нагреванием диамино-дифениловых оснований с соответствующими ацилуксусными эфирами по способу, подобному тому, который описывает Гейдрих (Heidrich), дл приготовлени бензидинида диацето-уксусной кислоты (Monatshefte fur Chemie-19 стр. 694).by heating the diamino-diphenyl bases with the corresponding acyl acetic esters according to a method similar to that described by Heidrich for the preparation of diaceto acetic acid benzidine (Monatshefte fur Chemie-19, p. 694).
Бензидинид дибензоил- уксусной кислоты кристаллизуетс из разбавленного пиридина, в виде тонких, желтых заостренных чешуек, которые , разлага сь, плав тс при 248° (неточно). Он растворим в лед ной уксусной кислоте и пиридине, мало растворим в спирте, нерастворим в эфире.Dibenzoyl acetic acid benzidinide crystallizes from diluted pyridine as thin, yellow, pointed scales that decompose melt at 248 ° (inaccurate). It is soluble in glacial acetic acid and pyridine, slightly soluble in alcohol, insoluble in ether.
