摘要： Two procedures are described that can be used to prepare polyhalogenated phenyl isocyanates (2,4,6-trichloro,2,3,5,6-tetrachloro, pentachloro, 2,4,6-tribromo and 2,4,6-trifluoro derivatives) from the corresponding anilines in good yields (95-99%) with small amounts of urea byproducts (1-5%) within reasonable reaction times (3-6 hours). These are:1. Liquid phase phosgenation of polyhalogenated anilines with tertiary amines as a hydrogen chloride acceptor.2. Liquid phase phosgenation of polyhalogenated anilines in excess phosgene at the beginning and throughout the reaction.

摘要： This invention is a method for the protection of wood and other lignocellulosic materials from attack by micro-organisms with the use of iodates. The method consists of treating wood or other lignocellulosic material by soaking it in a solution of iodate for a period of time ranging from three hours to seven days at temperatures between 20.degree. C. and 50.degree. C. The treated material is then removed from the solution and dried. Wood treated with this method shows resistance to attack by wood-degrading micro-organisms. Furthermore, the iodates are resistant to leaching from the wood and other lignocellulosic materials after such treatment.

摘要： Reaction of lignocellulosic material with uncatalyzed acetic anhydride in the absence of any cosolvent is disclosed. The process improves dimensional stability and resistance to biological attack of the lignocellulosic material. Lignocellulosic material is treated by exposure to liquid acetic anhydride for at least a short period of time, after which it is then heated to acetylate the material. The excess anhydride and byproduct acetic acid can be removed by vacuum.

摘要： Wood products impregnated with from 30 to 80% of a polymerizable monomer selected from the group consisting of hexanediol diacrylate and hexanediol dimethacrylate have excellent indent resistance. The wood products are impregnated with the monomer solution by placing the wood under a vacuum to remove air, contacting the wood with a monomer solution containing a polymerizable hexanediol diacrylate and/or hexanediol dimethacrylate monomer and from 0.5 to about 2 percent of a thermally activated free radical source as a polymerization initiator for a period sufficient to achieve the desired polymer loading. The wood is then heated under pressure to polymerize or cure the monomers.

摘要： Apparatus for impregnating wood veneer with a liquid impregnant comprises a container having an upper chamber communicated to a lower impregnation chamber. A clamping mechanism is releasably engageable to a peripheral region of the wood veneer and is cooperably received in the upper chamber in a manner to suspend the wood veneer in the impregnation chamber. An elevator overlies the container and is releasably connectable to the clamping mechanism for lowering the clamping mechanism into the upper chamber to suspend the wood veneer in the impregnation chamber therebelow. The clamping mechanism is disconnected from the elevator such that the clamping mechanism remains in the upper chamber during impregnation of the wood veneer with liquid impregnant. The impregnation chamber is evacuated by a vacuum pump after the wood veneer is suspended therein, and liquid impregnant is introduced from a storage tank to the impregnation chamber about the wood veneer. A venting valve is openable to establish ambient pressure in the impregnation chamber to impregnate the wood veneer with the liquid impregnant therein. Following impregnation, the clamping mechanism is reconnected to the elevator to enable removal of the impregnated wood veneer from the container.
