Description

Verfahren zur Gewinnung von einem für-, Genußzwecke geeigneten Zucker aus pflanzlichen Stoffen, wie Holz, Torf u. dgl., mittels hochkonzentrierter Säuren. In dem Zucker, der aus pflanzlichen Stoffen, wie Holz, Torf u. dgl., durch Aufschließen dieser Stoffe mit Hilfe hochkonzentrierter Säuren, z. B. hochkonzentrierter Salzsäure, gewonnen wird, befinden sich Stoffe, die dem Zucker einen bitteren Geschmack verleihen und den Zucker für Genußzwecke weniger geeignet machen.Process for the production of a sugar suitable for consumption from vegetable materials such as wood, peat and the like, using highly concentrated acids. In the sugar, which is made from vegetable matter such as wood, peat and the like these substances with the help of highly concentrated acids, e.g. B. highly concentrated hydrochloric acid, is obtained, there are substances that give the sugar a bitter taste and make the sugar less suitable for consumption.

Dieser Nachteil wird gemäß der Erfindung dadurch beseitigt, daß die pflanzlichen Stoffe vor der Hydrolyse mit gewissen Flüssigkeiten behandelt werden, welche Fette und Harze lösen, wie z. B. Äther, Alkohol, Kohlenwasserstoffe und deren Derivate, wie Benzol, Petroleumäther, Benzin, Trichloräthylen, Äthylenchlorid usw. oder Mischungen davon.This disadvantage is eliminated according to the invention in that the vegetable substances are treated with certain liquids before hydrolysis, which dissolve fats and resins, such as B. ether, alcohol, hydrocarbons and their Derivatives such as benzene, petroleum ether, gasoline, trichlorethylene, ethylene chloride, etc. or mixtures thereof.

Es ist zwar schon bekannt, bei der Herstellung von reiner Zellulose aus Holz letzteres zunächst mit harz- und fettlösenden Mitteln zu behandeln, um die der Zellulose anhaftenden harzigen Bestandteile zu entfernen. Es entstehen bei diesem bekannten Verfahren außer der reinen Zellulose, auf deren Gewinnung das Verfahren abzielt, Nebenprodukte, welche wertvolle Bestandteile, insbesondere Kohlehydrate enthalten, die auf Glykose weiterverarbeitet werden sollen. Dabei kommt für die Glykosegewinnung ebenfalls die Hydrolyse mittels Säuren in Anwendung. Indessen erfolgt die Hydrolyse bei dem bekannten Verfahren entsprechend dem abweichenden Zweck derselben im Gegensatz zu dem Verfahren der Zuckergewinnung, um welches es sich hier handelt, nicht durch konzentrierte Säuren, sondern durch verdünnte Säuren. Das bekannte Verfahren ist also in seinem Gesamteffekt vollkommen verschieden von dem vorliegenden.Although it is already known in the production of pure cellulose from wood to treat the latter first with resin and fat dissolving agents in order to to remove the resinous components adhering to the cellulose. It arise at this known process except the pure cellulose, on whose production the process aims to produce by-products, which are valuable constituents, especially carbohydrates that are to be processed on glucose. Here comes for the Glycose production also uses acid hydrolysis. In the meantime it takes place the hydrolysis in the known method according to the different purpose of the same in contrast to the process of sugar extraction, which is involved here, not by concentrated acids, but by diluted acids. The known procedure is therefore completely different from the present one in its overall effect.

Während die Gewinnung reiner Zellulose aus Holz die Entfernung der harzigen Bestandteile zur unerläßlichen Voraussetzung hat, geht die Hydrolyse mittels hochkonzentrierter Säuren zwecks Zuckerbildung auch bei Anwesenheit der harzigen Bestandteile anstandslos vor sich. Es entsteht nur ein Zucker mit bitterem Geschmack. Die Erfindung besteht in der Erkenntnis, daß dieser bittere Geschmack dadurch beseitigt werden kann, daß man die Pflanzenstoffe einer Vorbehandlung mit harz- und fettlösenden Mitteln unterwirft. Diese Vorbehandlung hat demnach hier eine grundsätzliche andere Bedeutung als bei dem bekannten Verfahren, wo sie nur die Isolierung der Zellulose von den-Inkrusten bezweckt.While the extraction of pure cellulose from wood involves the removal of the has resinous components as an indispensable requirement, the hydrolysis takes place by means of highly concentrated acids for the purpose of sugar formation even in the presence of resinous ones Components in front of you without hesitation. The result is only a sugar with a bitter taste. The invention consists in the recognition that this eliminates this bitter taste can be that the plant substances a pretreatment with resin and fat dissolving Subjects to means. This pretreatment is therefore fundamentally different here Significance than in the known process, where they only isolate the cellulose Purpose of the-Incrusts.
