Description
При осуществлении способа получени в одном процессе светлой экстракционной канифоли и .высококачественных окисленных смол с помощью высущенной отбельной земли производитс извлечение из канифоли окисленных темных веществ, которые концентрируютс и удерживаютс .сорбентом. Этот удержанный сорбентом концентрат экстрагируетс бензином дл удалени нормальных смол ных и жирных кислот, после чего окисленные смолы извлекаютс активными растворител ми и увариваютс .In the process of producing in a single process light extraction rosin and high-quality oxidized resins with the help of dried bleaching earth, oxidized dark substances are extracted from the rosin, which are concentrated and retained by the adsorbent. This sorbent-retained concentrate is extracted with gasoline to remove normal gum and fatty acids, after which the oxidized gums are extracted with active solvents and boiled down.
Предложение дает новый способ извлечени смолы из отработанного сорбента: концентрированные и удержанные сорбентом вещества вначале целиком извлекаютс из него активным растворителем, увариваютс и лишь затем подвергаютс отделению от нормальных смол ных и жирных кислот.The proposal provides a new method for extracting resin from a spent sorbent: the substances concentrated and retained by the sorbent are first completely removed from it with active solvent, boiled down and only then separated from normal resin and fatty acids.
Этот прием может представить известные преимущества при работе с канифолью, содержащей большие количества окисленных веществ (например , извлеченной активными растворител ми).This technique may present well-known advantages when working with rosin containing large amounts of oxidized substances (for example, recovered with active solvents).
Часть этих веществ, как известно, выпадает уже в стадии приготовлени растворов канифоли. По своему составу эти осадки весьма близки к концентратам, извлекаемым из сорбента.Some of these substances, as is known, fall out already in the stage of preparation of rosin solutions. In composition, these sediments are very close to the concentrates extracted from the sorbent.
Поэтому переработку их может оказатьс целесообразным вест1 совместно с извлеченными из сорбента концентратами.Therefore, their processing may be advisable West1 together with concentrates extracted from the sorbent.

Предмет изобретени Subject invention
Способ извлечени смолы из отработанного сорбента при сорбционной очистке канифоли путем обработки его органическими растворител ми , отличающийс тем, что .сорбент экстрагируют растворител ми , извлекающими как окисленную, так и неокисленную смолу, а экстракт после отгонки растворител обрабатывают легкими «ефтепогонами и тому подобными селективными растворител ми дл неокисленной смолы, с целью отделени окисленной смолы от неокисленной.A method of extracting resin from a spent sorbent during sorption purification of rosin by treating it with organic solvents, characterized in that the adsorbent is extracted with solvents that remove both oxidized and non-oxidized resin, and the extract after distillation of the solvent is treated with light solvent and the like selective solvent for the non-oxidized resin, in order to separate the oxidized resin from the non-oxidized one.
