    摘要: Wood preserving metal salts of organic carboxylic acids are impregnated into wood by an improved process which comprises impregnating the wood with an aqueous or organic solution of the salt in a cyclical process involving at least one high pressure cycle in which the solution is impregnated into the wood and a reduced pressure cycle in which a portion of the impregnating solution exudes from the wood, the improvement involving impregnating the wood during the high pressure cycle under conditions such that there is substantially no fixing of the metal in the wood, so that the metall:acid ratio of the solution exuded from the wood during the low pressure cycle is substantially the same as the metal:acid ratio of the original solution. At the end of the cyclical process, the impregnated wood is heated to fix the metal therein.

    摘要: ( We provide amine sahs of the general formula
    [wherein R 1 represents an aliphatic hydrocarbyl group containing from 6 to 20 carbon atoms; R 2 represents an aliphatic hydrocarbyl group containing from 1 to 20 carbon atoms; R 3 represents a hydrogen atom or an alkyl group containing from 1 to 3 carbon atoms; and HX is selected from a range of organic acids], each of which possesses useful biocidal activity.
