Description

Verfahren zur Behandlung von Wollfett. Bei der Verarbeitung des Wollfettes wird vielfach so vorgegangen, daß dasselbe ohne jegliche Vorbehandlung trocken destilliert wird. Hierbei gehen ungebundene, niedrigere aliphatische Alkohole nebst freien Fettsäuren bis zu einem Molekulargewicht von zgo unzersetzt ins Destillat.Method of treating wool fat. When processing the wool fat the procedure is often so that the same is distilled dry without any pretreatment will. Here, unbound, lower aliphatic alcohols go along with free fatty acids up to a molecular weight of zgo undecomposed in the distillate.

Der Restanteil, welcher aus freien, höher molekularen Fettsäuren und \eutralfett besteht, erfährt eine weitgehende Spaltung unter Bildung von niedrigeren Fettsäuren und von Kohlenwasserstoffen, hauptsächlich der Reihe C"H2n angehörend, geht demnach zersetzt ins Destillat über.The remainder, which consists of free, higher molecular fatty acids and \ eutralfat exists undergoes extensive splitting with the formation of lower ones Fatty acids and hydrocarbons, mainly belonging to the C "H2n series, is therefore decomposed into the distillate.

Hierbei ist das Verhältnis der zersetzten Destillationsprodukte zu dem unzersetzten Destillatanteüle gemäß den Bestandteilen des Ausgangsproduktes ein sehr ungünstiges und liefern solche Verfahren nur ein minderwertiges Endprodukt.Here is the ratio of the decomposed distillation products to the undecomposed distillate according to the constituents of the starting product a very unfavorable and such processes only provide an inferior end product.

Der Erfinder hat gefunden, daß dieses Endresultat hinsichtlich des Fettsäuregehaltes ein wesentlich besseres Ergebnis liefert, wenn Wollfett unter Druck in einem absolut geschlossenen Autoklaven mit Wasser bei etwa i5o° C gespalten wird und das entwässerte Material direkt oder mittels überhitzten Wasserdampfes mit oder ohne Zuhilfenahme von Vakuum destilliert wird.The inventor has found that this end result in terms of Fatty acid content gives a much better result if wool fat is under Pressure split in an absolutely closed autoclave with water at about 150 ° C and the dewatered material directly or by means of superheated steam is distilled with or without the aid of vacuum.

Andere Spaltmittel als Wasser eignen sich nicht für dieses Verfahren.Breaking agents other than water are not suitable for this process.

Beispiel. iooo kg vorgetrocknetes Wollfett gelangen mit 400 -1,9 Wasser in ein mit Rührwerk versehenes Druckgefäß obengenannter Beschaffenheit und werden binnen einigen Stunden bis etwa i 5o' C erhitzt. Hierauf gelangt die Masse über ein Expansionsgefäß in einen Absatzbottich, worin sich das Spaltwasser binnen kurzem glatt abscheidet und abgelassen wird. Die Masse wird alsdann getrocknet und gelangt zur Destillation.Example. 10000 kg of pre-dried wool fat get with 400-1.9 water into a pressure vessel of the above type equipped with a stirrer and become heated to about 15oC within a few hours. The mass then passes over an expansion vessel into a vat, in which the cracked water is within a short time is deposited and drained smoothly. The mass is then dried and discharged for distillation.
