| Regulatorische Informationen | Chemical: Butane, 1,1'-[oxybis(2,1-ethanediyloxy)]bis-Butane, 1,1'-[oxybis(2,1-ethanediyloxy)]bis- is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Butane, 1,1'-[oxybis(2,1-ethanediyloxy)]bis- are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)S - indicates a substance that is identified in a final Significant New Use Rule.Status: Active Update: 10-07-2019 https://echa.europa.eu/registration-dossier/-/registered-dossier/5839Butane, 1,1'-[oxybis(2,1-ethanediyloxy)]bis-: Does not have an individual approval but may be used under an appropriate group standard |
| Brandgefahren | Special Hazards of Combustion Products: Vapor may travel considerable distance to a source of ignition and flash back. (USCG, 1999) |
| Gesundheitsgefahren | May be harmful by inhalation, ingestion and skin absorption. Causes eye and skin irritation. Material is irritating to mucous membrane and upper respiratory tract. (USCG, 1999) |
| Gefahrenübersicht | Oxidizes in air and may cause explosive peroxidesA skin and eye irritant[CAMEO] See Monoglyme. |
| Reaktive Gruppe | Ethers |
| Reactivity Alerts | Peroxidizable Compound |
| Reactivity Profile | DIETHYLENE GLYCOL DIBUTYL ETHER may react violently with strong oxidizing agents. Incompatible with nitric acid. May form salts with strong acids and addition complexes with Lewis acids. In other reactions, which typically involve the breaking of the carbon-oxygen bond, relatively inert. |
| Air and Water Reactions | Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick, 1979 p.151-154, 164]. Insoluble in water. |
| Hazard Classes and Categories | Not Classified |
| Brandbekämpfung | Fire Extinguishing Agents: Water spray, dry chemical, alcohol foam. (USCG, 1999) |
| Erste Hilfe | EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.INHALATION: IMMEDIATELY leave the contaminated areatake deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be usedif not available, use a level of protection greater than or equal to that advised under Protective Clothing.INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992) |
| Freisetung ohne Brand | SMALL SPILLS AND LEAKAGE: If you spill this chemical, FIRST REMOVE ALL SOURCES OF IGNITION. Then, use absorbent paper to pick up all liquid spill material. Your contaminated clothing and absorbent paper should be sealed in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with 60-70% ethanol followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.STORAGE PRECAUTIONS: You should keep this material in a tightly closed container under an inert atmosphere, and store it at refrigerated temperatures. (NTP, 1992) |
