Description

[Detailed description of the invention]

The present invention relates to a smoke agent composition, and more particularly, as a smoke base, the general formula [] (In the formula, R is a hydrogen atom, an alkali metal or
NH ₄ is shown, and n is an integer of 1 to 2. ) This relates to a smoking agent composition containing a compound represented by: Conventional smoke compositions include those consisting of an oxidizing agent and a combustion agent, those containing a nitrate ester compound with a combustion suppressant, and those using an organic blowing agent such as azodicarbonamide, etc. It has been widely used as a commercial insecticide and as a pest control agent for agriculture and horticulture. However, among these smoke compositions, smoke agents that are made by blending an oxidizing agent and a combustion agent in appropriate proportions, such as oxidizing agents such as chlorates, perchlorates, chromates, and nitrates, In combustion-type smoking agents containing combustion agents such as wood flour, starch, and sulfur, the temperature during smoking reaches approximately 400℃ or higher, which makes it difficult to prevent the loss of insecticidal or bactericidal components due to thermal decomposition. Not only is it difficult, but the gases generated during smoking include ammonia, nitrogen oxides, halogens,
Contains harmful gases such as sulfur oxides, and if used incorrectly in facility cultivation, it can cause smoke damage to plants and corrode metal products. In addition, smoking agents containing nitrate ester compounds and combustion inhibitors have a low smoking temperature, but they generate nitrogen oxides, which are harmful to plants when used in high doses, and Smoking agents containing organic blowing agents such as dicarbonamide generate large amounts of ammonia, and when used in facility cultivation, they have extremely harmful effects on plants and cause many problems such as corroding metal products. There were flaws. Furthermore, in conventional products, some substances have unstable exothermic base components, which poses safety problems during production, storage, and use. As a result of various studies conducted by the present inventors to solve these problems, we found that a smoke agent composition containing a compound represented by the general formula [] as a smoke base contains nitrogen oxides, ammonia, etc. The present invention was completed based on the discovery that it emits little harmful gas, has almost no corrosive effect on metals or plants, and can effectively volatilize active ingredients. That is, the present invention is a smoking agent composition characterized in that a compound represented by the general formula [] is blended as a smoking base. The compound represented by the general formula [ ] used in the present invention is Beilstein Bond (Beilstein Bond).
