Description

Известны способы получени  красителей дл  крашени  полиамидов в массе. Однако эти красители-периноны не обладают достаточной глубиной окрашивани .Known methods for producing dyes for dyeing polyamides in bulk. However, these dyes perinones do not have a sufficient depth of staining.

Предлагаемый способ отличаетс  тем, что, 5,6-диаминоаценафтен конденсируют с нафталевым ангидридом или его 4-бензоилпроизводным при нагревании в среде уксусной кислоты. Эти красители (ацепериноны ) позвол ют получать окраски, не уступаюш,ие по прочности окраскам из соответстБуюш.их перинонов, причем окрашивание получают более глубокое.The proposed method is characterized in that 5,6-diamino-acetafaphene is condensed with naphthalic anhydride or its 4-benzoyl derivative when heated in an acetic acid medium. These dyes (acepherinones) make it possible to obtain stains that are not inferior to the strength of the stains from the corresponding shades of their perinones, and the staining gets deeper.

При осуш,ествлении способа нагревают смесь, состо ш,ую из 5,6диаминоаценафтена , нафталевого ангидрида (или 4-бензоилнафталевого ангидрида) и уксусной кислоты. Получаемый краситель отфильтровывают , промывают, переосаждают и сушат.During the drying process, the mixture is heated, consisting of 5,6 diaminoacenaphthene, naphthalic anhydride (or 4-benzoylnaphthalic anhydride) and acetic acid. The resulting dye is filtered off, washed, replanted and dried.

Пример 1. Смесь 1 г 5,6-диаминоаценафтена и 1,1 г нафталевого ангидрида внос т в лед ную (или 98%-ную) уксусную кислоту (20 мл) и кип т т с обратным холодильником в течение 3-4 час. Осадок образуюшегос  красител  отфильтровывают, промывают 98%-ной уксусной кислотой и водой. Перекристаллизовывают краситель из 98%-ной уксусной кислоты.Example 1. A mixture of 1 g of 5,6-diaminoacenaphthene and 1.1 g of naphthalic anhydride was added to ice (or 98%) acetic acid (20 ml) and heated to reflux for 3-4 hours. The precipitate of the resulting dye is filtered off, washed with 98% acetic acid and water. The dye is recrystallized from 98% acetic acid.

Выход 1,2 г (64%); температура плавлени  230°, цвет окрашенного в массе капрона светлый бордо. Прочности 0,5%-ной окраски на капроне (оценка прочности по п тибальной системе): вода - 5/5/5; стирка 50°-5/5/5; нот - 5/5/5; глажение - 5/5; трение сухое - 5; трение мокрое- 5; свет - 3; свет ногода - 3.Yield 1.2 g (64%); melting point 230 °, the color of the nylon colored burgundy. Strength of 0.5% coloring on caprone (strength assessment according to the tibal system): water - 5/5/5; wash 50 ° -5 / 5/5; notes - 5/5/5; ironing - 5/5; dry friction - 5; friction is wet- 5; light - 3; light foot - 3.

П р и м е р 2. Смесь I г 5,6-диаминоаценафтена, 1,65 s 4-бепзоилнафталевого ангидрида и 20 мл лед ной уксусной кислоты обрабатывают, как описано в примере 1.PRI mme R 2. A mixture of 1 g of 5,6-diamino-ctenaphthene, 1.65 s 4-bepsoylnaphthalic anhydride and 20 ml of glacial acetic acid is treated as described in Example 1.

№ 147275- 2 No. 147275-2

Выход красител  2,2 г (90%); температура плавлени  223-224°; цвет окрашенного в массе капрона - фиолетовый с красным оттенком. Прочности 0,5%-ной окраски на капроне: вода -5/5/5; стирка 50° - 5/ 5/5; пот - 5/5/5; глажение - 5/5; трение сухое - 4; трение мокрое - 5; свет - 3; свет погода - 3.The output of the dye 2.2 g (90%); melting point 223-224 °; the color of nylon colored in mass is purple with a red tinge. Durability of 0.5% coloring on caprone: water -5/5/5; wash 50 ° - 5 / 5/5; pot - 5/5/5; ironing - 5/5; dry friction - 4; wet friction - 5; light - 3; light weather - 3.
