Description
Patented Sept. 20, 1932 UNTED STATES PATENT OFFICE MAX HAGEDORN AND EUGEN Gll'HRING, F DESSAU IN ANHALT, GERMANY, ASSIGNORS TO I. G. FARBENINDUSTRIE AKTIENGESELLSCHAFT, 0F FRANKFORT-ON-THE-MAIN, GERMANY, A CORPORATION OF GERMANY PROCESS OF PRESERVING- WOOD No Drawing. Application filed December 20, 1928, Serial No. 327,473, and in Germany December 20, 1927.
The present invention relates to a process of preserving wood by impregnating it with a high molecular carbohydrate derivative containing a radicle of a higher fatty acid,
l. for instance, of lauric acid or stearicacid.
By such impregnation the wood is rendered entirely Water-proof and decay thus becomes impossible.
As said carbohydrate derivatives containi ing a radicle of a higher fatty acid may be mentioned esters, ether-esters and mixed esters of cellulose or starch. They are'used in a li uid state preferably molten or dissolved 1n a suitable organic solvent. If de- 151 sired, antiseptic agents may be added to the substances used for the impregnation. Other additions may also be made, for instance of dyestuffs for producing special patterns or the like. i
The wood may, for instance, be impregniited as indicated in the following examp es.
Emample 1.The wood to be treated is freed from air and then impregnated, un-
der pressure, with a solution of 10 parts by weight of cellulose-trilaurate in 100 parts of an organic solvent,for instance, dichloromethane, chloroform or benzene.
molten condition, by application of pressure, into the wood to be treated.
An insoluble cellulose-trilaurate may be applied in the same manner.
What we claim is 1. The process of preserving wood by impregnating it with a carbohydrate derivative of the group consisting of lauric and stearic acid esters, mixed esters and ether-esters of Ewa'mple 2.A starch-laurate having a melting point above 100 C. is forced in a taining in their molecule the residue of lauric acid.
4. The process of preserving wood by impregnating it with a. cellulose ester of lauric acid.
In testimony whereof, we aflix our signa tures.
