化学的特性
Benzenesulfonohydrazides,unlike the benzenesulfonamides, are thermally unstable. They decompose, when heated in water in some cases, to form sulfides, thiosulfonates, and nitrogen; for this reason they are used as blowing agents in the production of foams.
化学的特性
Benzenesulfonyl hydrazide is WHITE POWDER

| 火災危険 | Excerpt from ERG Guide 149 [Substances (Self-Reactive)]:Self-decomposition, self-polymerization, or self-ignition may be triggered by heat, chemical reaction, friction or impact. May be ignited by heat, sparks or flames. Some may decompose explosively when heated or involved in a fire. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. May burn violently. Decomposition or polymerization may be self-accelerating and produce large amounts of gases. Vapors or dust may form explosive mixtures with air. (ERG, 2024) |
| 健康有害性 | Excerpt from ERG Guide 149 [Substances (Self-Reactive)]:Inhalation or contact with vapors, substance or decomposition products may cause severe injury or death. May produce irritating, toxic and/or corrosive gases. Runoff from fire control or dilution water may cause environmental contamination. (ERG, 2024) |
用途
説明
Benzenesulphonyl hydrazide (BSH) is a chemical blowing agent used to modify the cell structure of natural rubber. The decomposition temperature of BSH blowing agent is 105 °C, and its gas release rate is 120 cm3/g. In the preparation of natural rubber thermal insulation materials, the BSH blowing agent decomposes upon heating to produce nitrogen gas, thereby forming a foam structure within the rubber. When the BSH content is 6 phr, the maximum swelling ratio reaches 324% and the thermal conductivity reaches a minimum of 0.040 W/m/K, making the material an excellent thermal insulation material [1]. Furthermore, BSH is also used as the core material in evaporable core-shell nanocapsules to enable thermally triggered separation of thin films [2].
使用
Benzenesulfonyl hydrazide is used in making foam rubber and foam plastics.
