Description
Известен способ дублени голь , состо щий в обработке последнего водным раствором кристаллических органических соединений, содержащих сульфо- или карбоксильные группы или обе группы вместе.There is a known method for tanning a mole consisting in treating the latter with an aqueous solution of crystalline organic compounds containing sulfo or carboxyl groups or both groups together.
Предлагаемый способ дублени голь заключаетс в применении в качестве дубильных веществ растворов сульфированного диоксидитолилметана или 2-6 нафталсульфокислоты , обработанной серной кислотой и формальдегидом. Вышеуказанные дубители могут быть примен емы или в отдельности или в смеси с другими дуб щими или недуб щими веществами.The proposed tanning method involves using solutions of sulfated dioxyditolylmethane or 2-6 naphthal sulfate acids treated with sulfuric acid and formaldehyde as tannins. The aforementioned tanning agents can be used either individually or in a mixture with other tanning or non-nesting substances.
Пример 1. Дл получени дуб щего раствора поступают следующим образом;Example 1. To obtain a tanning solution, proceed as follows;
50 частей диоксидитолилметана формулы50 parts of dioxyditolmethane formula
ОН ОЯOH OH
/ ч // h /
- .-.
раствор ют в 200 част х серной кислоты 66° Вё при обыкновенной температуре и оставл ют сто ть до тех пор, пока проба, разбавленна лед ной водой не даст прозрачного раствора. Затем массу выливают на лед, составл ющий 400 весовых частей и насыщакэт поваренной солью, при чем выпадает в мелко-кристаллической форме натриева соль образовавшейс сульфокислотьь Осадок отсасывают, промывают раствором поваренной соли, прессуют и сушат . Этот продукт раствор ют в воде с прибавлением серной кислоты и дуб т этим раствором обычным образом. Пример 2. Раствор ют 44,8 частей 2 - 6 нафтолсульфокислоты в 250 част х 40%-ной серной кислоты и нагрев до 80° ввод т при помешивании 10 частей 30%-ноге формальдегида . Продукт конденсации тотчас же начинает выкриста.лизовыватьс в блест щих листочках. Размешивание продолжают до исчезновени запаха формальдегида и по охлаждении отсасывают осадок. Отпрессованную массу раствор ютDissolve in 200 parts of 66 ° Be sulfuric acid at ordinary temperature and leave to stand until the sample diluted with ice water gives a clear solution. Then the mass is poured onto ice, constituting 400 weight parts, and saturated with sodium chloride, the sodium salt formed in the finely crystalline form, the resulting sulfonic acid. The precipitate is sucked off, washed with sodium chloride solution, pressed and dried. This product is dissolved in water with the addition of sulfuric acid and the oak is mixed with this solution in the usual way. Example 2. 44.8 parts 2-6 naphtholsulfonic acid are dissolved in 250 parts of 40% sulfuric acid and 10 parts of 30% formaldehyde are added with stirring to 80 °. The condensation product immediately begins to creep into shiny leaves. Stirring is continued until the smell of formaldehyde disappears and the precipitate is sucked off after cooling. The pressed mass is dissolved
