KAISERLICHESIMPERIAL
Die Neuerungen bezwecken die Darstellung von reinem wasserfreien Stärkezuckerdextrose-Anhydryt C6 H12 O6, und insbesondere die Gewinnung eines solchen mit krystallinischer Structur. Man concentrirt Stärkezuckerlösung im Vacuum, bis eine herausgenommene Probe nach dem Erkalten kaum knetbar ist. Der so erhaltene Syrup, nicht über 700C. erwärmt, wird in geschlossenen Gefäfsen mit kochend heifsem Methylalkohol sehr innig gemischt. Die Menge des gereinigten Holzgeistes hängt von der Reinheit des Stärkezuckers und auch von der erwarteten Beschaffenheit des Productes ab. Wendet man gewöhnlichen Stärkezucker an, der 20' bis 30 pCt. Nichtzucker enthält, dann nimmt man auf 100 Theile Syrup 70 bis 80 Theile Holzgeist und läfst in geschlossenen Gefäfsen bei einer Temperatur von 30 bis 400 C. krystallisiren. The aim of the innovations is to produce pure anhydrous starch sugar dextrose anhydrate C 6 H 12 O 6 , and in particular to obtain one with a crystalline structure. The starch-sugar solution is concentrated in a vacuum until a sample that has been taken out can hardly be kneaded after cooling. The syrup thus obtained, not heated above 70 0 C., is mixed very intimately in closed Gefäfsen with boiling heifsem methyl alcohol. The amount of purified wood spirit depends on the purity of the starch sugar and also on the expected quality of the product. If one uses ordinary starch sugar, which is 20 'to 30 pCt. Does not contain sugar, then is taken up in 100 parts of syrup 70 to 80 parts of wood alcohol and läfst crystallize in closed Gefäfsen at a temperature of 30 to 40 0 C..
Die Krystallisation wird durch Einwerfen von wasserfreiem krystallisirten Stärkezucker beschleunigt. Die körnige Masse kann man mittelst Centrifugalkraft oder mittelst Pressen von der Flüssigkeit trennen und durch Aussüfsen oder Ausdecken weiter reinigen. Körniger, poröser Stärkezucker in festen Stücken, mit deutlich ausgebildeten und spiegelnd glänzenden Krystallen von dem Ansehen der Rohrzuckerraffinade wird wie folgt erzeugt:The crystallization is accelerated by throwing in anhydrous crystallized starch sugar. The granular mass can be removed by means of centrifugal force or by pressing Separate the liquid and clean it further by spraying it out or covering it. Granular, porous Starch sugar in solid pieces, with clearly developed and shiny crystals from the look of the cane sugar refinade is generated as follows:
Man concentrirt eine vollkommen klare und farblose Stärkezuckerlösung, welche von fremden Substanzen'möglichst befreit sein mufs, im Vacuum bis zu der oben genannten Consistenz. Der Syrup mufs so klar wie Wasser bleiben; sollte er infolge von Krystallbildung sich auch nur ganz wenig getrübt haben, was mitunter infolge eines zu langsamen oder unterbrochenen Abdampfens vorkommt, dann würde er für den nachfolgenden Procefs wegen der gebildeten wasserhaltigen Krystalle ungeeignet sein.A perfectly clear and colorless starch-sugar solution is concentrated, which is from foreign Substances must be freed as far as possible, in a vacuum up to the consistency mentioned above. The syrup must remain as clear as water; it should also develop as a result of the formation of crystals have only slightly clouded it, sometimes as a result of too slow or interrupted work If evaporation occurs, then he would be educated for the subsequent Procefs because of the water-containing crystals may be unsuitable.
Man mischt 100 Gewichtstheile des klaren Syrups, welcher auf ungefähr 700 C. erwärmt wurde, mit 10 bis 25 Gewichtstheilen kochend heifsen, möglichst reinen Methylalkohols, bis die Masse gleichförmig dünn syrupös wird. Diese wird dann, noch heifs, in verschliefsbare konische Formen gefüllt. Man läfst nun langsam auf 30 bis 35° C. abkühlen und erhält die Masse auf dieser Temperatur, bis die Krystallisation beendigt ist, was zwei bis drei Tage dauert. Das Flüssiggebliebene wird nach dieser Zeit abgesaugt.Mixing 100 weight parts of the clear syrup, which was heated to about 70 0 C., with 10 to 25 parts by weight of boiling torrid, very pure methyl alcohol, until the mixture is uniformly thin syrupös. This is then, while still hot, filled into lockable conical shapes. It is now allowed to cool slowly to 30 to 35 ° C. and the mass is kept at this temperature until the crystallization has ended, which takes two to three days. Anything that has remained liquid is sucked off after this time.
Wünscht man einen dichten und festen Zucker, so sättigt man, nach dem Absaugen des Flüssiggebliebenen, die poröse Masse ein- oder zweimal mit einer Mischung von ioq Theilen concentrirten Syrups und 80 bis 100 Theilen Holzgeist. Diese Operation, wie die fernere Krystallisation kann bei gewöhnlicher Temperatur erfolgen. Ist die gewünschte Dichtigkeit erreicht, so wird der flüssige Theil abgesaugt und mit möglichst- reinem Methylalkohol verdrängt und ausgedeckt. 5 pCt. vom Gewicht des Zuckers genügen für letzteren Zweck. Man nimmt nun ■die soliden Brode aus den Formen und beseitigt den Methylalkohol aus denselben, indem man sie in eine Vacuumpfanne mit gut ausgekühlter Vorlage bringt und den Methylalkohol abdestillirt. Man tiiut dies anfänglich bei einer Temperatur von 300C. und steigert erst die Temperatur auf 50 bis 6o° C, wenn die gröfste Menge ab-If a thick and solid sugar is desired, the porous mass is saturated once or twice with a mixture of 100 parts concentrated syrups and 80 to 100 parts wood spirit after sucking off the liquid which has remained. This operation, like the further crystallization, can be carried out at ordinary temperature. When the desired tightness is achieved, the liquid part is sucked off, displaced and covered with the purest possible methyl alcohol. 5 pct. the weight of the sugar suffice for the latter purpose. The solid bread is then removed from the molds and the methyl alcohol is removed from them by placing them in a vacuum pan with a well-cooled receiver and distilling off the methyl alcohol. One tiiut this initially at a temperature of 30 0C and only increases the temperature to 50 to 6o ° C when the greatest amount off
destillirt ist. Wenn der Zucker einige Stunden bei der' letzteren Temperatur in der Luftleere erhalten wird, so kann man weder durch den Geschmack, noch den Geruch eine Spur von dem Methylalkohol wahrnehmen. Von der abgesaugten Flüssigkeit erhält man den Methylalkohol gleichfalls wieder durch Destillation im Vacuum oder in gewöhnlicher Weise. Der ganze Verlust an Methylalkohol beträgt Vi0, so dafs der wirkliche Verbrauch davon für das letztbeschriebene Verfahren nur 2 bis 2 Y2 pCt. beträgt. is distilled. If the sugar is kept in the vacuum for a few hours at the latter temperature, no trace of the methyl alcohol can be perceived by taste or smell. The methyl alcohol is likewise obtained from the liquid which has been sucked off by distillation in a vacuum or in the usual way. The total loss of methyl alcohol is Vi 0 , so that the actual consumption of it for the process described last is only 2 to 2 Y 2 pCt. amounts to.
