摘要:
A fumigant, comprising cyanogen (C2N2) (as herein defined), provides a viable alternative to conventional fumigants such as methyl bromide, phosphine and carbonyl sulphide. Experiments have shown that cyanogen (C2N2) can be used as such a fumigant, in the control of a range of biota, including insects, mites, nematodes, fungi and their spores, viruses, spiders, bacteria, moulds and rodents. It is also suitable for use on a variety of commodities, including grain, seeds, meats, fruit, vegetables, timber, plants, cut flowers and soil. It is shown that an efficacious concentration of cyanogen (C2N2) as a fumigant leaves a very low residue and can be readily flushed from commodities. In particular, it has been observed that a mixture of cyanogen (C2N2) and carbon dioxide have a synergistic effect, when applied to various biota. Throughout the specification, it should be noted that the term 'cyanogen' is defined as the gas (at STP) cyanogen, C2N2, essentially free from hydrogen cyanide and other cyanogenic compounds (that is, compounds that give rise to hydrogen cyanide). Cyanogen, which has also been termed dicyan and oxalonitrile, as a fumigant, may be shown as (CN)2, C2N2 or NC-CN.
摘要:
The invention relates to the use of an aminocarboxylic acid or aminocarboxylate in the preservation of wood against attack from insects, particularly from termites of the Coptotermes family or the house longhorn (Hylotrypes bajulus).

The invention comprises a process for the preservation of timber with a boron based compound, such as trimethyl borate. The timber is dried to a low moisture content, is then subjected to a vapour of the boron compound in a suitable treatment vessel, and after vapour treatment is steam conditioned to return the moisture content of the timber to a normal working level. The vapour treatment is preferably carried out under heat and reduced pressure.
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.
