Description
Konservierungs- und DesodorierungsmitteL Gegenstand vorliegender Erfindung ist ein Konservierungs- und Deso-dorierungsmit- tel, bestehend in einer Lösung eines wasser löslichen Reaktionsproduktes von Harnstoff und seinen Derivaten mit Formaldehyd.
Es wurde gefunden, dass wässerige Lö sungen der löslichen Kondensationsprodukte von Harnstoff und Derivaten mit Formalde <B>hyd</B> sich in liervorraggnder Weise zur Kon servierung leicht verderblicher Materialien, wie zum Beispiel von Därmen, Häuten, Fleisch usw. eignen. Schon in starker Ver dünnung macht sich die konservierende Wir kung dieser Lösungen geltend, wie Versuche zeigen. So zum Beispiel behalten Därme, die in eine verdünnte Lösung dieser Produkte eingelegt werden, ihre natürliche Farbe und bleiben weich und dehnbar.
Des Weiteren wurde gefunden, dass die Lösungen oder Harnstoff - Formaldehydkon densationsprodukte eine sehr ausgeprägte desodorierende Kraft besitzen. Insbesondere lassen sich üble Gerüche, herrührend von tie rischen Fäulnisprodukten, leicht und rasch entfernen, indem man die zu desodorierenden Räume, Behälter, wie zum Beispiel Fässer usw., mit den Lösungen bespritzt bezw. die Lösungen darin zerstäubt.
Zur Herstellung .des Produktes gemäss der Erfindung verwendet man vorteilhaft Harn stoff- bezw. Harnstoffderivat-Formaldehyd- kondensationsprodukte, die nicht mehr als 2 Mol. Formaldehyd auf 1 Mol. Harnstoff bezw. Harnstoffderivat enthalten und wel che frei sind von überschüssigem Form aldehyd.
Gewünschtenfalls können den Lösungen noch andere Stoffe bezw. Stoffgemische zu gesetzt werden, die entweder konservierend oder desodorierend wirken, oder die gleich zeitig beide Funktionen auszuüben vermögen, wodurch die Wirkung in geeigneten Fällen vorteilhaft unterstützt werden kann. <I>Beispiel 1:</I> Eine Lösung des Kondensationsproduk tes aus 3 Teilen Harnstoff und<B>8,2</B> Teilen 36 %iger Formaldehydlösung wird mit einer in der Wärme hergestellten Lösung von 12 Teilen Natronsalpeter in 8 Teilen Wasser gemischt.
Diese Lösung wird so weit ver dünnt, dass auf 1 bis 1@ Teile Trocken gemisch 20 Teile Wasser kommen. In die so erhaltene Lösung können zum Beispiel 100 bis 150 Teile des. zu konservierenden #2,la.te- rials, wie zum Beispiel Därme us@v., einge legt werden.
Beispiel <I>2:</I> 1 Teil Dimethylolliarnstoff, 1. Teil Koch salz und 1 Teil Natronsalpeter werden zii- sammen in 10 bis 15 Teilen mässig warmem Wasser gelöst. Die so. erhaltene Lösung kann vor dem Gebrauch auf 40 bis 50 Teile W'asser verdünnt und wie in Beispiel 1 ver- =endet werden.
<I>Beispiel 3:</I> Eine Lösung des Kondensa,tionspro-duk- tes aus 5 Teilen Harnstoff und 13,7 Teilen 36 ,äigem neutralisiertem Forma.lidehyd wird mit einer Lösung von 10 Teilen Salpeter in h Teilen ZVasser gemischt. Die Lösung kann eventuell nach weiterem Verdünnen als Kon- servierungsmittel, wie in Beispiel 1, oder zum Desodorieren von Fässern, Räumen usw. ver- ivendet werden.
Preservatives and deodorants The present invention relates to a preservative and deodorant, consisting in a solution of a water-soluble reaction product of urea and its derivatives with formaldehyde.
It has been found that aqueous solutions of the soluble condensation products of urea and derivatives with formaldehyde are particularly suitable for the preservation of perishable materials such as intestines, skins, meat, etc. Even in strong dilution, the conserving effect of these solutions asserts itself, as tests show. For example, casings soaked in a diluted solution of these products retain their natural color and remain soft and elastic.
It has also been found that the solutions or urea-formaldehyde condensation products have a very pronounced deodorizing power. In particular, unpleasant odors, originating from tie-ric putrefaction products, can be easily and quickly removed by spraying the rooms to be deodorized, containers such as barrels, etc. with the solutions. the solutions in it are atomized.
For the production of the product according to the invention it is advantageous to use urea or urea. Urea derivative-formaldehyde condensation products which contain no more than 2 mol. Formaldehyde to 1 mol. Urea or. Contain urea derivative and which are free from excess form aldehyde.
If desired, the solutions can bezw other substances. Mixtures of substances are set that either have a preservative or deodorant effect, or which are able to perform both functions at the same time, whereby the effect can be advantageously supported in suitable cases. <I> Example 1: </I> A solution of the condensation product from 3 parts of urea and 8.2 parts of 36% formaldehyde solution is mixed with a hot solution of 12 parts of sodium nitrate in 8 parts Water mixed.
This solution is diluted to such an extent that there are 1 to 1 parts of dry mix 20 parts of water. For example, 100 to 150 parts of the # 2, la.terials to be preserved, such as intestines us @ v., Can be placed in the solution obtained in this way.
Example <I> 2: </I> 1 part of dimethyl sulphide, 1st part of sodium chloride and 1 part of sodium nitrate are dissolved together in 10 to 15 parts of moderately warm water. The so. The solution obtained can be diluted to 40 to 50 parts of water before use and terminated as in Example 1.
<I> Example 3: </I> A solution of the condensation product from 5 parts of urea and 13.7 parts of 36% neutralized formaldehyde is mixed with a solution of 10 parts of saltpeter in 1 parts of water. After further dilution, the solution can possibly be used as a preservative, as in Example 1, or for deodorizing barrels, rooms, etc.
