Fire retardant compositions and methods for preserving wood products
Wood preservative compositions are disclosed. Treatment of lumber, plywood, and other wood products with a novel composition comprising the boron source composition, a melamine binder resin, and a urea casein activator resin protects lumber, plywood, and other wood products from attack by termites, fungi, fire and flame. The preservative can be formed by combining a source of boron such as boric acid and the water-soluble salts thereof, a melamine binder resin, and a urea casein resin. A wood preservative is characterized by a weight ratio of the urea casing activator resin to the melamine binder resin ranging from about 1:20 to 1:4 and a weight ratio of the boron source composition to the melamine binder resin ranging from about 1.3:1 to 9.6:1.

Methods are disclosed for forming heptan-4-one, and, optionally, heptan-4-ol, from fermentable sugars. The sugars are fermented using a bacteria or yeast that predominantly forms butyric acid. The butyric acid is subjected to catalytic ketonization conditions to form heptan-4-one, with concomitant loss of water and carbon dioxide. The heptan-4-one can be subjected to catalytic hydrogenation to form heptan-4-ol, an either of these can be included in gasoline compositions. In one aspect, the fermentable sugars are derived from lignocellulosic materials such as wood products, switchgrass, or agricultural wastes, which are delignified to form lignin, cellulose and hemicellulose. The cellulose and hemicellulose can be depolymerized to form glycose and xylose, either or both of which can be fermented by the bacteria. Thus, the methods described herein can convert biomass to a fuel composition or fuel additive, which can be used in a conventional gasoline engine, unlike traditional fuels such as ethanol or biodiesel.
