Patented July 29, 1952 I WOOD PRESERVATIVE COMPRISING CHLO- RINATED P H E N O L I C S, AN THRACENIC OILS, AND CREOSOTES Lucien Rouzet, Paris, France, assignor to Societe dos Laboratoires de Recherches pour Applicaof France No Drawing,

,and especially railway against weather and attack .by moisture, fungus, insects and the like, it has long been customary to impregnate the, wood with the so-c-alled creosote oils obtained from the distillation of coal tars. obtained from high temperature carbcnisation. For the same purpose, it has also already been proposed to use anth'racenic oils obtained from the distillation of coal tars (mainly the socalled pressure oils) and also anthracenic cakes or sludges obtained as Icy-products from such distillation, dissolved, for example, in the oils obtained from the distillation up to 160 C. of the same tars.
I have found, and the present invention is based on the discovery, that certain substances which do not themselves have exceptional fungicidal properties, possess the surprising property of reinforcing the fungicidal properties of numerous antiseptics, and especially those enumerated above, when mixed with these antlseptics in very small proportions of from about 0.2 to 0.5% by weight of thetotal mixture. Such additives thus enable the same fungicidal effects to be obtained with much smaller quantities of these known impregnating antiseptics.
These substances which augment the power of the known antiseptics, and which are hereinafter designated by the term booster, are quite numerous but may be defined in general terms as the chloro substitution products of phenols,
cresols, naphtols, polyphenols and saturated carbocyclic aliphatic hydrocarbons.
Accordingly, the present invention consists in a wood impregnating preservative comprising a mixture of a known antiseptic and fungicidal product, such as creosote oil or ranthracenic oil, with a very small proportion of from about 0.2 to 0.5% by weight of the total mixture of a booster substance which reinforces the anti septic properties of said known product and which consists of a chloro substitution product of a phenol, cresol, naphtol, polyphenol or cyclic hydrocarbon.
Among'these various derivatives the following have been found to be particularly effective,
namely, parachlormetacresol, trichlorphenol, trichlorcresol, pentachlorphenol, hexachlorcyclohexane, and orthophenylphenol.
These various boosters have been proved as effective with compositions such as these used iuider the name of creosote oils for impregnating railway sleepers, as with anthracenic oils and sludges, and have conferred upon them a greatly tions Industrielles, Paris, France, a corporation Application masher .12, 1947, Se- 791,458. In France December 30, 1946 Claims. (c1. 167527) increasedactivity and a gr a Value i ba ing the various causes of timber decay.
In accordance with the invention also} the above-mentioned anthracenic oils or dissolved anthracenic sludges or cakes are given improved impregnating properties, and consequently greater efliciency, by mixture with petroleum-hydrocarbons, such as kerosene, gas oil or fuel oil, which may be employed in the proportion'of about 30 to of the total mixture, f i
Moreover, an'addition of from about lto 5% of naphthalene to the mixtures described increases the fixation of the deposit in the ligneous layers. By virtue of its crystallisation in the ligneous cells, the naphthalene contributes to prevent migration of the semi-liquid substances and also absorbs the solids, so that the resistance of a combination to the weather becomes perfect.
For example, highly satisfactory results have been obtained with a solution containing:
10% of anthracenic cakes or sludges obtained from the cooling, filtration or pressure treatment of crude anthracenic oils obtained from the distillation of coal tar,
3% of naphthalene,
This solution has proved to be as powerful a fungicide and insecticide as the heavy creosote oil of analogous composition commonly used for impregnating railway sleepers.
Very favourable results have also been obtained with mixtures, in various proportions, of a solution such as that specified above and the heavy creosote oil commonly used for impregnation; for example, a mixture of two parts of the solution to one part of creosote oil.
It has also been found that the specified boosters exercise a very marked activating influence on other substances than those, 1. e., the heavy creosote oils and anthracenic oils or sludges, commonly used for impregnating timber. Thus, certain schist oils derived from the pressure treatment, distillation or carbcnisation of bituminous schists, and oils obtained from the distillation of tars derived from the low temperature carbcnisation of coal, may be mixed with the specified fungicide boosters. These mixto anthracenic sludges or oils or to creosote oils obtained from the distillation of coal tars obtained from high temperature carbonisation.
