KLASSE 23: Fettindüstrie.CLASS 23: Fat Industry.
Fatentirt im Deutschen Reiche vom 20. Juni 1886 ab.Fatentirt in the German Empire from June 20, 1886.
Meine Erfindung kommt zur Anwendung bei dem Verfahren, aus den durch Schwefelsäureverseifung dargestellten dunklen, penetrant riechenden Fettsäureproducten und aus den anwesenden noch unvollständig verseiften Neutralfetten durch Destillation und gleichzeitige Rectification in ein und demselben Apparat geruchlose, weifslichgelbe, stearinhaltige Fettsäuren zu gewinnen.My invention is used in the process made by sulfuric acid saponification shown dark, penetrating smelling fatty acid products and from those present Neutral fats that are still incompletely saponified by distillation and simultaneous rectification in one and the same apparatus to odorless, whitish-yellow, stearic fatty acids to win.
Die Neuerung besteht darin, die vor der Destillation durch Erhitzen entwässerten, dunklen, rohen Fettsäuren nach der Destillation einen Rectificationsapparat durchlaufen zu lassen, in welchem übertretende Fettsäuren beim Herabströmen eine Anzahl Siebe durchdringen, wobei ein am Boden eintretender Dampfstrahl gegen dieselben strömt und die etwa mit den Fettsäuren zur Condensation gelangten, übelriechenden Bestandteile mit sich reifst, dieselben nach einem Kühler leitend, in welchem die noch vorhandenen Fettsäuren condensirt und mit den im Rectificationsapparat schon vorhandenen nach einer Condensationsschlange und von hier zur weiteren Verwendung abgelassen werden.The innovation is that the dehydrated before distillation by heating, dark, raw fatty acids pass through a rectification apparatus after distillation to let, in which overflowing fatty acids penetrate a number of sieves as they flow down, whereby a jet of steam entering at the bottom flows against the same and that for instance with the fatty acids for condensation the malodorous components that have come to the fore, directing them to a cooler, in which the remaining fatty acids condense and with those in the rectification apparatus already existing can be drained after a condensation coil and from here for further use.
Die aus dem letzterwähnten Kühler, entweichenden übelriechenden Producte werden gleichfalls abgeleitet.The foul-smelling products escaping from the last-mentioned cooler become also derived.
Der Apparat ist folgendermafsen construirt:The apparatus is designed as follows:
Derselbe besteht aus einem unteren cylindrischen Gefäfs C, in welches die condensirten Fettsäuren durch das Zuflufsrohr O geführt werden. Der Apparat ist mit einer Anzahl Siebe q und einem Vertheiler ^1 versehen und trägt ein durchlochtes Dampfrohr q1 in seinem Boden, in welchen auch eine Kühlschlange s einmündet, die in dem Kühlgefäfs s1 liegt und zur Ableitung der condensirten Fettsäuren dient.It consists of a lower cylindrical vessel C, into which the condensed fatty acids are led through the inlet pipe O. The apparatus is provided with a number of sieves q and a distributor ^ 1 and has a perforated steam pipe q 1 in its bottom, into which a cooling coil s opens, which lies in the cooling vessel s 1 and serves to drain off the condensed fatty acids.
Die in C entwickelten Dämpfe werden durch das Rohr t nach dem Kühlapparat t1 geführt, der in dem oberen gesonderten Theil C1 des Rectificationsapparates liegt. Der cylindrische Theil C1 dient als Kühlgefäfs und ist mit Wasserzulauf u und Wasserablauf ul versehen.The vapors developed in C are conducted through the pipe t to the cooling apparatus t 1 , which is located in the upper separate part C 1 of the rectification apparatus. The cylindrical part C 1 serves as a cooling vessel and is provided with water inlet u and water outlet u l .
Aus dem Kühlapparat t1 werden die flüchtigen Producte durch das Rohr f2 abgeleitet, während die neuerdings wieder condensirten Fettsäuren durch ein Abfiufsrohr t3 nach dem Rectificator C und zur Kühlschlange s gelangen, von der sie abgezogen werden.The volatile products are discharged from the cooling apparatus t 1 through the pipe f 2 , while the recently condensed fatty acids pass through an outflow pipe t 3 to the rectifier C and to the cooling coil s , from which they are withdrawn.
Die Fettsäuren werden beim Herabfliefsen durch die Siebe von einem aus dem Rohr q2 austretenden Dampfstrahl bestimmter Temperatur getroffen, wodurch die . übelriechenden Producte und ein Theil der Fettsäuren nach dem Kühlapparat, der eine bestimmte Temperatur besitzt, übergeführt werden.As they flow down through the sieves, the fatty acids are hit by a jet of steam at a certain temperature emerging from the pipe q 2, which causes the. malodorous products and a part of the fatty acids are transferred to the cooling apparatus, which is at a certain temperature.
Die mitgerissenen Fettsäuren condensiren sich wieder und gelangen mit den durch die Siebe gegangenen reinen Fettsäuren nach der Kühlschlange s, aus welcher sie abfliefsen.The entrained fatty acids condense again and, with the pure fatty acids that have passed through the sieves, reach the cooling coil , from which they flow off.
Die übelriechenden Producte entweichen aus dem Kühlapparat i1 als Aerolein, Kohlen-The malodorous products of escape from the cooling apparatus 1 as i Aerolein, carbonic
Wasserstoffe etc., und können zu weiterer Verwendung gewaschen und condensirt werden.Hydrogen etc., and can for further use be washed and condensed.
Die aus der Condensationsschlange austretenden Fettsäuren sind beinahe weifs und geruchlos; es wird aus ihnen durch Pressung Stearinsäure nebst für die Seifenfabrikation ausgezeichneter Oelsäure gewonnen.The fatty acids emerging from the condensation coil are almost white and odorless; It is made from them by pressing stearic acid together with for soap manufacture Obtained oleic acid.
