COMPOSITIONS OF MATTER AND METHODS FOR PRESERVING AND FIREPROOIEING WOOD.
No Drawing.
Specification of Letters Patent.
Patented @ct. 15, 1%12.
Application filed July 18,1912 Serial No. 710,177.
To all whom it may concern:
Be it known that we, FRIEDRICH SnmEN- SCHNUR, chemist, and JULIUS DEHNST, chemist, subjects of the King of Prussia, German Emperor, residing at 12 Holtzendorfi street, Charlottenburg, near Berlin, Kingdom of Prussia, German Empire, and 15 Joachim Friedrich street, Halensee, near Berlin, Kingdom of Prussia, German Empire, respectively, have invented a new and useful Improvement in Compositions of Matter and Methods or Processes for Preserving and Fireproofing Wood; and we do hereby declare the following to be a full, clear, and exact description of the same. Thisinvention relates to a composition of matter and a method or process for preserving and fireproofing wood described in the specification accompanying application for patent for which we have executed of even date herewith whereby wood is both preserved and rendered uninflammable by soaking it with solutions of salts of ammonium and magnesium and alpha-naphthalene sulfonates.
It'now appears that in impregnating w1th solutions of ammonium and magnesium salts, the nitro-substitution products of the naphthalene sulfonates can be used with special advantage as the antiseptic. Use may be made of the mono-nitro substitution products of both naphthalene monosulfonic acid and naphthalene disulfonic acid.
One advantage of using the nitro compounds consists in that the solutions employed for impregnation can be cooled much lower than is possible when solutions of ammonium-magnesium salts and alphanaphthalene sulfonates are used. The nitro havlng a stronger preservative action than the unsubstituted naphthalene sulfonates. The salts of zinc and magnesium are specially suitable. Thenitro-substitution products of naphthalene sulfonic acid may be used either alone or in association with the nit-flo-substitution products of the disulfonic aci It is remarkable that the nitro-compounds do not lower the fireproofing efi'e'ct of the mixture in any way as it might have been expected the nitro-substitution products would impair the security against fire. It is surprising to find, however, that the protective action against fire is even increased.
A single solution of the different salts may be prepared in the warm, and introduced into the wood in the known manner. On the other hand the salts may be introduced into the wood singly. For example, zinc nitro-naphthalene monosulfonate (which may, contingently, be used in admixture with the nitro-substitution products of the naphthalene disulfonates) can be introduced first, and then a solution of ammonium and magnesium sulfate. Ammonium and magnesium sulfate may also be introduced as separate solutions. In these cases it is advisable to employ the method according to the principal specification in which the wood is first impregnated with magnesium salts and then with ammonium salts. The nitro-naphthalene sulfonate's may also be introduced last.
Example: Wood is treated, according to one of the known methods of impregnation, with application of pressure and a vacuum, with a hot solution ofz-QOO parts of magnesium sulfate, 100 parts of ammonium sulfate, 20 parts of zinc nitro-naphthalene monosulfate in 1000 parts of water.
The pure salts may be used, and also the impure salts, obtained from the crude products, may find application. Difi'erent metallic salts may also be mixed together; the zinc salt and the magnesium salt, for example, of the sul-fonic acids being used together.
We claim:
1. The process for preserving wood and rendering it non-inflammable which consists in impregnating wood with salts of ammonium, salts of magnesium and salts of nitronaphthalene-sulfonic acids.
'2. The process for preserving wood and rendering it non-inflammable which consists in impregnating wood with salts of ammonium, salts of magnesium and salts of nitronaphthalene-disulfonic acids.
3-. Solution for preserving wood and rendering it non-inflammable composed of an I, 7 1,041,682 I i of magnesium and salts of nitronaphthaour names to this specification in the preslene-ssulfonie acids. ence of two subscribing witnesses. I 4. olution for preserving Wood and rendering it non-inflammable composed of an S E 5 aqueous solution of salts of ammonium, I
salt-s of magnesium and salts of ni-tronaph- Witnesses: thalene-disulfonic acids. HENRY HASPER,
In testimony whereof, We have signed NV LDEMAR HAUPT.
