Description
Verfahren zum Verfestigen von Aceton oder von acetonischen Lösungen Es ist bekannt, z. B. aus der französischen Patentschrift l 021 476, daß ein Gemisch aus 50 Teilen Aceton und 10 Teilen Wasser mit Hilfe eines Gemisches aus 5 Teilen Lanolin, 25 Tdilen Glykolstearat und 10 Teilen Polyäthylenoxyd zu einer Paste verdickt xverden kann. Das Produkt ist indessen durch ein, en sehr hohen Prozentsatz an dem Verfestigungsmittel gekennzeichnet, nämlich 40 Teile Festkörper auf 60 Teile Acetonlösung oder 40 °/o Festkörper im Fertigprodukt.Process for solidifying acetone or acetone solutions It is known e.g. B. from French patent l 021 476 that a mixture from 50 parts of acetone and 10 parts of water using a mixture of 5 parts Lanolin, 25 parts of glycol stearate and 10 parts of polyethylene oxide thickened into a paste xverden can. The product is, however, by a very high percentage of the Solidifying agents, namely 40 parts of solids to 60 parts of acetone solution or 40% solids in the finished product.
Es hat daher nicht an Versuchen gefehlt, Aceton oder acetonische Lösungen in vorteilhafterer Weise und mit anderen Mitteln zu verfestigen, es insbesondere in gelartige Irodukte umzuwandeln, die z. B. für kosmetische Zwecke geeignet sind. There has therefore been no lack of attempts, acetone or acetone To solidify solutions in a more advantageous manner and by other means, in particular to convert into gel-like Irodukte z. B. are suitable for cosmetic purposes.
So ließ sich z. P. 50 bis 70%iges wäßriges Aceton mit Hilfe eines Gemisches aus höhermolekularem Alkohol und Natriumcetylsulfat in fester Form bringen ; allein die erhaltenen Produkte karen nicht längere Zeit hindurch haltbar. So z. P. 50 to 70% aqueous acetone with the help of a Bring a mixture of higher molecular weight alcohol and sodium cetyl sulfate in solid form ; only the products obtained cannot be kept for a long time.
Andererseits führte sowohl ein Ersatz der Sulfate der höhermolekularen Alkohole bzw. der Arylsulfonate in dieser Mischung durch Polyäthylenoxyde als auch der Ersatz der höhermolekularen Alkohole selbst durch ihre Ester mit einbasischen organischen Säuren oder freie Fettsäuren nicht zur Verfestigung des Acetons oder seiner Lösungen Schließlich blieb dieser Erfolg auch versagt bei Verwendung von Alkyl- oder Arylpolyglykoläthern. On the other hand both a replacement of the sulfates by the higher molecular ones resulted Alcohols or the aryl sulfonates in this mixture by polyethylene oxides as well the replacement of the higher molecular weight alcohols themselves by their esters with monobasic ones organic acids or free fatty acids do not solidify the acetone or its solutions Ultimately, this success failed even when using Alkyl or aryl polyglycol ethers.
Es wurde nun gefunden, daß Alkylpolyglykoläther sich doch unter bestimmten Bedingungen zum Verfestigen von Acetonlösungen verwenden lassen. Die Herstelltmg gelartiger, fester Produkte aus Acetonlösungen mit diesen ist Gegenstand der Erfindung Es zeigte sich nämlich, daß einmal Alkylpolyglykoläther nur dann zum Verfestigen von Acetonlösungen tauglich sind. wenn sie etwa 6 bis 16 Glykolgruppen enthalten und ihre Alkylgruppe möglichst lang ist. z. 13. 16 und mehr Kohlenstoffatome umfaßt, und zum andern, daß auch diese besonderen Polyglykoläther, zusammen mit Stoffen gekoppelt die nur eine längere Alkylkette im Molekül enthalten, wie die höhermolekularen Alkohole oder ihre Ester mit einbasischen Säuren, die GelierungvonAcetonlösungennicht zu bewerkstelligen vermögen, sondern daß dazu Stoffe erforderlich sind. die im Molekül zwei oder mehr Alkylreste mit längerer Kohlenstoffkette enthalten. Es wurde schließlich gefunden, daß diese Alkylreste mindestens auch 16 oder. besser, mehr Kohlenstoffatome aufweisen müssen, wenn sie in dem gewünschten Sinne wirken sollen. It has now been found that alkyl polyglycol ethers are, after all, certain Allow conditions to solidify acetone solutions to be used. The manufacturing gel-like, solid products from acetone solutions with these is the subject of the invention It has been shown that once alkyl polyglycol ethers only solidify of acetone solutions are suitable. when they contain about 6 to 16 glycol groups and their alkyl group is as long as possible. z. 13. comprises 16 and more carbon atoms, and on the other hand, that these special polyglycol ethers, too, together with substances coupled that only contain a longer alkyl chain in the molecule, like the higher molecular ones Alcohols or their esters with monobasic acids, the gelation of acetone solutions does not able to accomplish, but that substances are required for this. those in the molecule contain two or more alkyl radicals with a longer carbon chain. It finally did found that these alkyl radicals are at least 16 or. better, more carbon atoms must have if they are to work in the desired sense.
An Stoffen der ersten Art erweisen sich nun Alkvlpolyglykoläther als brauchbar, die etwa 6 bis 16 Glykolgruppen und eine Alkylgruppe mit 18 oder mehr Kohlenstoffatomen enthalten ; die Stoffe der zweiten Art werdeen durch Ester höhermolekularer Alkohole von der Art des Arachylalkohols mit mehrbasischen organischen Säuren repräsentiert. Alkol polyglycol ethers are now found in substances of the first type as useful, the about 6 to 16 glycol groups and an alkyl group with 18 or more Contain carbon atoms; the substances of the second kind are derived from esters higher molecular weight alcohols of the type of arachyl alcohol with polybasic organic Acids represented.
Auffallend ist dabei, daß der Alkylpolyglykoläther insofern seine Rolle als etwaiger oberflächenaktiver S'toir einzubüßen scheint, als von ihm das Zwei-bis zweieinhalbfache des zweiten Stoffes an Gewicht gebraucht wird. It is noticeable that the alkyl polyglycol ether is its own Seems to lose its role as a possible surface-active S'toir than that of him Two to two and a half times the weight of the second fabric is needed.
Die Erfindung wird durch das folgende Beispiel erläutert : Beispiel 10 g Alkylpolyglykoläther, dessen Alkylgruppe 20 Kohlenstoffatome aufweist, werden mit 3, 5 g Bernsteinsäurediarachylester unter Erwärmen in 80 ml 50°/oigem wäßrigem Aceton gelöst Beim Erkalten mit oder ohne Rühren erstarrt die klare Lösung bei 42° C zu einem festen, transparenten Gel. The invention is illustrated by the following example: Example 10 g of alkyl polyglycol ethers, the alkyl group of which has 20 carbon atoms with 3.5 g of succinic acid diarachyl ester with heating in 80 ml of 50% aqueous Dissolved acetone. On cooling, with or without stirring, the clear solution solidifies at 42 ° C to a solid, transparent gel.
Der Prozentsatz der die Gelbildung bewirkenden Stoffe macht hier also nur 14, 4°/o, bezogen auf die Gesamtmasse des Produktes, aus, ist also gegenüber dem eingangs erwähnten französischen Verfahren auf rund ein Drittel herabgesetzt Durch sinngemäße Abwandlung des Beispiels können auch Ester der höhermolekularen Alkohole mit anderen zweibasischenund auch mit mehr als zweihasischen organischen Säuren für die Verfestigung von höherprozentigen Acetonlösungen angewendet werden. The percentage of the substances causing the gel formation makes here so only 14.4%, based on the total mass of the product, is therefore opposite the French procedure mentioned at the beginning is reduced to around a third By analogous modification of the example, esters of the higher molecular weight can also be used Alcohols with other dibasic and also with more than dibasic organic Acids can be used to solidify higher percentage acetone solutions.
Die Produkte riechen nicht mehr merklich nach Aceton. Sie lassen sich zudem parfümieren oder auch mit anderen Zusatzstoffen versehen, ohne zu zerfallen. The products no longer smell noticeably of acetone. You let also perfume themselves or add other additives without disintegrating.
