  • Chemische Eigenschaften Chemical properties of sulfur hexafluoride are very stable. And compared to selenium hexafluoride, the hydrolysis rate of sulfur hexafluoride is extremely low, this is due to the small radius sulfur atom, which resulting in six fluorine atoms form a larger steric hindrance around. However, the fluorine atom radius is not big, so the repulsive force between the six fluorine atoms is not too large, S-F bond is not easy to dissociate. Enthalpy of formation of sulfur hexafluoride is-1220 kJ/mol, but enthalpy of formation of sulfur hexafluoride is-74 kJ/mol. Thus, the radius of fluorine atom and sulfur atom radius cause the very stable of sulfur hexafluoride molecule together---the molecules themselves are difficult to disconnect bond and break down and the attack group is difficult to approach to the central atom, in the thermodynamics and kinetics, they are both stable. Studies have said sulfur hexafluoride can be stably present in the atmosphere for thousands of years.
  • Verwenden Sulfur hexafluoride is used extensively as a gaseous dielectric in various kinds of electrical power equipment, such as switchgear, transformers, condensers, and circuit breakers. It has also been used as a dielectric at microwave frequencies and as an insulating medium for the power supplies of high-voltage machines.
    Sulfur hexafluoride is also gaining use in nonelectrical applications, including blanketing of molten magnesium, leak detection, and plasma etching in the semiconductor industry. Sulfur hexafluoride also has some limited medical applications.
  • Trademarks SonoVue (for the microbubble formulation) (Ausimont).
  • Reaktivität anzeigen This substance undergoes chemical reactions only under relatively severe circumstances. They are resistant to ignition, although they may become flammable at very high temperatures. They may be resistant to oxidation reduction, except in the most severe conditions. These materials may be nontoxic. They can asphyxiate. Contact of very cold liquefied gas with water may result in vigorous or violent boiling of the product and extremely rapid vaporization due to the large temperature differences involved. If the water is hot, there is the possibility that a liquid "superheat" explosion may occur. Pressures may build to dangerous levels if liquid gas contacts water in a closed container [Handling Chemicals Safely 1980].
  • Hazard Asphyxiant.
  • Health Hazard Vapors may cause dizziness or asphyxiation without warning. Vapors from liquefied gas are initially heavier than air and spread along ground. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating, corrosive and/or toxic gases.
  • Brandgefahr Some may burn but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket.
  • Sicherheitsprofil This material is chemically inert in the pure state and is considered to be physiologcally inert as well. However, as it is ordinarily obtainable, it can contain variable quantities of the lowsulfur fluorides. Some of these are toxic, very reactive chemically, and corrosive in nature. These materials can hydrolyze on contact with water to yield hydrogen fluoride, which is highly toxic and very corrosive. In high concentrations and when pure it may act as a simple asphyxiant. Incompatible with disilane. Vigorous reaction with disilane. May explode. When heated to decomposition emits highly toxic fumes of Fand SOx.
  • mögliche Exposition May contain highly toxic sulfur pentafluoride as an impurity. SF6 is used in various electric power applications as a gaseous dielectric or insulator. The most extensive use is in high-voltage transformers. SF6 is also used in waveguides, linear particle accelerators; Van de Graaff generators; chemically pumped continuous-wave lasers; transmission lines; and power distribution substations. Nonelectrical applications include use as a protective atmosphere for casting of magnesium alloys and use as a leak detector or in tracing moving air masses. Several sources note that vitreous substitution of SF6 in owl monkeys results in a greater ocular vascular permeability than that caused by saline. This implies that SF6 could have an important use in retinal surgery.
  • Versand/Shipping UN1080 Sulfur hexafluoride, Hazard Class: 2.2; Labels: 2.2-Nonflammable compressed gas. Cylinders must be transported in a secure upright position, in a wellventilated truck. Protect cylinder and labels from physical damage. The owner of the compressed gas cylinder is the only entity allowed by federal law (49CFR) to transport and refill them. It is a violation of transportation regulations to refill compressed gas cylinders without the express written permission of the owner.
  • Inkompatibilitäten May contain impurities that cause it to hydrolyze on contact with water, forming corrosive and toxic hydrogen fluoride. Vigorous reaction with disilane.
  • Waste disposal Return refillable compressed gas cylinders to supplier. Seal unused cylinders and return to suppliers.
  • Chemische Eigenschaften Sulfur pentafluoride and sulfur tetrafluoride are classified by OSHA as highly hazardous chemicals under its Process Safety Management Standard and as toxic industrial chemicals on the basis of their highly toxic nature and production in large quantities (29 CFR 1910).
