Procédé pour la conservation du bois.
La présente invention concerne un procédé pour la conser- vation du bois. Il est connu pour la protection du bois contre l'attaque des champignons, d'employer des solutions des sels de composés nitrés organiques, en particulier du dinitrophénol avec des bases organiques, ces solutions étant employées seu- les ou en mélange avec des sels anorganiques et d'autres addi- tions.
Il a maintenant été découvert qu'à la place des sels, employés exclusivement depuis longtemps, du dinitrophénol avec des bases aromatiques, on peut utiliser avantageusement les
<Desc/Clms Page number 2>
sels de phénols nitrés avec des amines oxyalkylées. Ces sels sont beaucoup plus facilement solubles dans l'eau et, mélangés à d'autres substances comme par exemple des sels anorganiques ou d'autres additions comme l'aldéhyde formique ou des compo- sés donnant par dissociation de l'aldéhyde formique, ils se dissolvent encore facilement, ils présentent cet autre avan- tage que leurs solutions aqueuses attaquent le fer à un degré encore moindre que les solutions des sels correspondants d'a- mines aromatiques, et que même en cas de cuisson il ne s'échap pe pas de quantités notables de la,
base organique sous la forme de vapeur.
On a trouvé particulièrement appropriés entre autres
EMI2.1
les sels du dinitràphénoi avec la mono- et la di-oxyéthylani- line, et en particulier les sels formés avec des oxyalkylami- nes aliphatiques comme les mono-, di- et tri-oxyéthylamine et les oxypropylamines correspondantes. Ces derniers sels peu- vent s'employer également avec des additions anti-corrosives comme le bichromate de potassium.
On imprègne par exemple du bois de pin, d'une manière connue, avec emploi de vide et de pression, au moyen d'une solution à 2 % d'un mélange consistant en 85,5 % de fluorure de sodium, 2,5% de fluorure de zinc, 1,0 % d'hexaméthylène- tétramine et 11,0% de dinitrophénol-oxyéthylaniline par le remplacement de la dinitrophénol-oxyétylaniline par de la dinitrophénol-oxyéthylamine ou -oxypropylamine (ces dernières consistant en un mélange des bases primaires, secondaires et tertiaires comme on l'obtient par exemple par l'action d'oxy- de d'éthylène ou d'oxyde de propylène sur l'ammoniaque,) on arrive à des mélanges d'imprégnation $ayant des propriétés en- core meilleures de solubilité.

Process for preserving wood.
The present invention relates to a process for preserving wood. It is known for the protection of wood against the attack of fungi, to use solutions of the salts of organic nitro compounds, in particular dinitrophenol with organic bases, these solutions being used alone or in admixture with inorganic salts. and other additions.
It has now been discovered that instead of the salts, which have been used exclusively for a long time, of dinitrophenol with aromatic bases, it is possible to advantageously use the salts.
<Desc / Clms Page number 2>
salts of nitrated phenols with oxyalkylated amines. These salts are much more easily soluble in water and, mixed with other substances such as, for example, inorganic salts or other additions such as formaldehyde or compounds which give formaldehyde by dissociation, they They dissolve still easily, they have the other advantage that their aqueous solutions attack the iron to a still less degree than the solutions of the corresponding salts of aromatic amines, and that even in case of cooking it does not escape. no significant amounts of the,
organic base in the form of vapor.
It has been found particularly suitable among others
EMI2.1
salts of dinitraphenol with mono- and di-oxyethylaniline, and in particular the salts formed with aliphatic oxyalkylamines such as mono-, di- and tri-oxyethylamine and the corresponding oxypropylamines. These latter salts can also be used with anti-corrosive additions such as potassium dichromate.
For example, pine wood is impregnated, in a known manner, with the use of vacuum and pressure, by means of a 2% solution of a mixture consisting of 85.5% sodium fluoride, 2.5 % zinc fluoride, 1.0% hexamethylene tetramine and 11.0% dinitrophenol-oxyethylaniline by the replacement of dinitrophenol-oxyethylaniline by dinitrophenol-oxyethylamine or -oxypropylamine (the latter consisting of a mixture of the bases primary, secondary and tertiary as obtained for example by the action of ethylene oxide or propylene oxide on ammonia,) we arrive at $ impregnation mixtures having properties in- better solubility core.
