|---|---|
| 規制情報 | Restricted substance: Tetraammonium hexacyanoferrate |
| 有害性の概要 | Emergency treatment: Irritants[HSDB] Ferrocyanide complexes are stable and practically nontoxic because of the strong bonding between iron and cyanide. Cyanide ions may be formed slowly when the chemical is irradiated with UV light. [Ullmann] May cause irritation[MSDSonline] |
| RCRA 要件 | /SRP:/ D003A solid waste containing ammonium ferrocyanide may become characterized as a hazardous waste when subjected to testing for reactivity as stipulated in 40 CFR 261.23, and if so characterized, must be managed as a hazardous waste. |
| EPA Hazardous Waste Number | D003/SRP:/ A waste containing ammonium ferrocyanide may (or may not) be characterized a hazardous waste following testing for the reactivity characteristics as prescribed by the Resource Conservation and Recovery Act (RCRA) regulations. |
| 清浄水法要件 | Toxic pollutant designated pursuant to section 307(a)(1) of the Federal Water Pollution Control Act and is subject to effluent limitations. /Cyanides/ |
| Hazard Classes and Categories | Acute Tox. 4 (88.9%) |
| Hazardous Reactivities and Incompatibilities | At 220 °C interaction with ammonium hexacyanoferrate is explosive in wet mixtures, or in dry mixtures if the nitrate is in excess. |
| 保管条件 | PROTECT FROM LIGHT. |
| 処分方法 | Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number D003, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste. |
製法・合成法
純化方法
The pale yellow trihydrate powder can be washed with 10% aqueous NH3, filtered, then washed several times with EtOH and Et2O, and dried at room temperature. It decomposes in a vacuum above 100o and should be stored away from light and under N2. In light and air it decomposes by losing NH3. [Lux in Handbook of Preparative Inorganic Chem (Ed. Brauer) Academic Press Vol II p 1509 1965.]
