Description
Известны способы получени таннидов экстракцией различных растительных дубильных материалов с добавками сульфита натри или сернисто-кислых солей аммони .Methods are known for the preparation of tannins by the extraction of various vegetable tanning materials with the addition of sodium sulphite or ammonium sulphate.
С целью увеличени выхода таннидов и улучшени их качества предложен способ экстракции таннидов в присутствии поверхностноактивного вещества, например сульфонола. Сульфонол добавл ют в жидкий экстракт перед сушкой.In order to increase the yield of tannids and improve their quality, a method for the extraction of tannids in the presence of a surfactant, such as sulfonol, has been proposed. The sulfonol is added to the liquid extract before drying.
Пример 1. Измельченную дубовую кору перерабатывают в опытной экстракционной батарее, состо щей из шести экстракторов емкостью 1 л. Экстрагируют чистой водой без добавлени химикатов (в контрольном опыте) или с добавлением сульфонола в количестве 1о/о от веса перерабатываемого материала, например дубовой щепы (услови процесса одинаковы в обоих опытах).Example 1. The crushed oak bark is processed in a pilot extraction battery consisting of six extractors with a capacity of 1 l. Extracted with pure water without the addition of chemicals (in the control experiment) or with the addition of sulfonol in an amount of 1 / / on the weight of the processed material, such as oak chips (process conditions are the same in both experiments).
В табл. 1 привод тс характеристики соков и экстрактов, полученных по описываемому способу.In tab. 1 shows the characteristics of the juices and extracts obtained by the described method.
Из приведенных данных следует, что при воздействии сульфонола таннидность и доброкачественность соков и экстрактов повышаетс , а количество нерастворимых, вл ющихс балластом, уменьшаетс . Выход таннидов повышаетс на 14,3о/о.From the above data, it follows that when exposed to sulfonol, the tannin content and purity of the juices and extracts increase, and the amount of insoluble, which is ballast, decreases. The yield of tannids increased by 14.3 o / o.

Пример 2. Измельченные корни тарана перерабатывают по технологии, описанной в примере 1.Example 2. Crushed roots of the ram are processed according to the technology described in example 1.
В табл. 2 привод тс основные ноказатели полученных соков и экстрактов.In tab. 2 summarizes the main indicators of the juices and extracts obtained.

25 3 Выход таннидов повышаетс при применеНИИ сульфонола на 6,3o/(i. Пример 3. В жидкий дубовый экстракт концентрацией около 300 г1л сухих веществ добавл ют сульфонол в количестее5%от веса5 сухих веществ и нагревают при 80°С в течекие 1 час. Выход танцидов повыщаетс на 6% по сравнению с контрольным опытом. 4 Предмет изобретени Способ получени таннидов экстракцией растительных материалов, обличающийс тем, что, с целью увеличени выхода таннидов и улучщени их качества, процесс провод т в присутствии поверхностно-активного вещества , например сульфонола.25 3 The yield of tannids is increased by applying 6.3 o / s. The yield of tancides rises by 6% compared with the control experiment 4 Subject of the invention A method for the production of tannins by the extraction of plant materials, in order to increase the yield of tannids and improve their quality, in the presence of a surfactant phonola.
