    摘要： The invention relates to an improved process for drying and preserving wood products. The improved process comprises the steps of first drying the wood products by submerging them in a naphthalene poor, coal tar based heat transfer medium under conditions of elevated temperature and reduced pressure. The dried wood products then are impregnated with a naphthalene rich, coal tar based wood preservative agent by submerging said dried wood products in said agent under conditions of both elevated temperature and pressure.

    摘要： Disclosed is a method of reducing insect and microbial decay in wood. The method comprises the steps of:a) immersing the wood in a treatment solution comprising i) a C1-C6monoalkanolamine ester of boric acid (e.g., monoethanolamine ester of boric acid) and ii) creosote; andb) exposing the immersed wood from step a) to conditions which cause the release of boron from the C1-C6 monoalkanolamine ester of boric acid (monoethanolamine ester of boric acid) and which cause the boron to migrate into the interior of the wood.

    摘要： Provided is a wood treatment composition comprising a reaction product produced by reacting a mixture, which includes creosote and a fatty ester component, in the presence of a Lewis acid catalyst. The reaction mixture may optionally include bunker oil and/or a borate ester. The mixture may comprise i) at least about 85 wt % creosote; and ii) at least about 1 wt % of an ester component containing one or more C8-C50 fatty esters. Also provided are wood treated with the composition and methods for using the composition to treat wood.

    摘要： An environmentally-friendly method is disclosed for transforming preserved wood, for example creosote-treated or CCA-treated wood with supercritical water. The product of treating weathered creosote-treated wood is a mixture that is similar to fresh creosote. The novel system is akin to a closed-loop system for recovering and rejuvenating creosote. In another aspect of the invention, acidic supercritical water is used to extract copper, chromium, and arsenic from CCA-treated wood, or more generally, to extract metals from an organic matrix.

    摘要： A composition for impregnation of a lignocellulosic material such as wood or wood particles, comprises a high boiling point tar acid or a pitch derived from coal; a solvent for the tar acid or pitch selected from a low carbon alcohol, an aceotrope of a low carbon alcohol and another solvent, and a mixture of a lower carbon alcohol and water; a phenol formaldehyde resole resin; an acid catalyst for the phenol formaldehyde resole resin; and preferably a formaldehyde donor or a precursor thereof. There is also disclosed a method of preparing a finished product from a lignocellulosic material by using the impregnating composition.
