Description

Verfahren zur Gewinnung technisch verwertbarer Produkte aus Tallöl Es ist nach dem Stande der Technik bekannt, Tallöl im Vakuum, gegebenenfalls mit Unterstützung von Wasserdampf, zu destillieren, zu dem Zwecke, das Tallöl in seine beiden Hauptkomponenten, Fettsäure und Harzsäure, zu zerlegen. Diese bekannten Methoden aber zeigen die Nachteile, daß einmal der Gehalt an Unverseifbarem durch die Destillation nicht vermindert, ja verschiedentlich noch erhöht wird, und zum zweiten, daß im Destillat das Vorhandensein an Harzsäuren noch sehr beträchtlich ist, meist über 30°10, so daß also diese beiden Methoden den Zweck der Trennung nur höchst unvollkommen erreichen.Process for obtaining technically usable products from tall oil It is known from the prior art, tall oil in a vacuum, optionally with Support of steam, to distill, for the purpose of bringing the tall oil into its two main components, fatty acid and resin acid, to break down. These known methods but show the disadvantages that on the one hand the unsaponifiable content from the distillation is not diminished, even increased in various ways, and secondly, that im The presence of resin acids is still very considerable, mostly over distillate 30 ° 10, so that these two methods only very imperfectly serve the purpose of the separation reach.

Die Erfindung vermeidet diese übelstände durch Behandlung des Tallöls im Hochvakuum, also bei einem Druck von weniger als 8 mm (v g1. H o u b e n , Die Methoden der organischen Chemie, -Leipzig 1921, Band I, S. 549). Die Herabsetzung des Harzsäuregehaltes kann noch dadurch gefördert werden, daß man Fraktionieraufsätze benutzt. Man kommt hierbei zu Destillaten, in denen sich Harzsäure nur noch im Ausmaße von etwa 5°1o befindet. Zur Behandlung nach dem Verfahren gemäß der Erfindung eignet sich sowohl gewöhnliches Tallöl als auch vorbehandeltes, z. B. ganz oder teilweise esterifiziertes Tallöl. Beispiel Man destilliert das Tallöl bei einem Druck von etwa 4 mm oder darunter. Stellt man fest, daß die Harzsäure zu destillieren beginnt, so wird der Vorgang unterbrochen. In diesem Augenblick ist die Trennung der Komponenten des Tallöls in einer Vollkommenheit erreicht, wie sie bisher technisch nicht durchführbar war. Bei Verwendung eines Fraktionieraufsatzes mit z. B. Raschigringen erhält man ein Destillat, welches Unverseifbares nur noch in ganz unbeträchtlicher Menge, beispielsweise bis Aa, und Harzsäure im Ausmaße von etwa 5°/o enthält.The invention avoids these inconveniences by treating tall oil in a high vacuum, i.e. at a pressure of less than 8 mm (v g1. H o u b e n, Die Methods of organic chemistry, Leipzig 1921, Volume I, p. 549). The degradation the resin acid content can still be promoted by using fractionating attachments used. This leads to distillates in which resin acid is only present to a large extent of about 5 ° 1o. Suitable for treatment according to the method according to the invention both ordinary tall oil and pretreated, e.g. B. in whole or in part esterified tall oil. Example The tall oil is distilled at a pressure of about 4 mm or less. If you notice that the resin acid begins to distill, so the process is interrupted. At that moment there is the separation of the components of tall oil achieved in a perfection that was previously not technically feasible was. When using a Fraktionieraufsatzes with z. B. Raschig rings are obtained a distillate, which is unsaponifiable only in very inconsiderable quantities, for example to Aa, and resin acid to the extent of about 5%.
