Chemische Eigenschaften

Octafluorocyclobutane is a colorless liquefied gas with an ethereal odor. Poor warning properties at low concentrations. Asphyxiant in high concentrations. Gas density is heavier than air. Octafluorocyclobutane is an etching agent.

Verwenden

Refrigerant; heat-transfer medium.
Halocarbon 318 is used for plasma etching. When it is exposed to the RF field generated in the etching process, a gas plasma is produced that will etch silicon compounds with excellent selectivity.

Definition

ChEBI: A fluorocarbon that is cyclobutane in which all eight hydrogens are replaced by fluorines.

Allgemeine Beschreibung

Octafluorocyclobutane is a colorless nonflammable gas. Octafluorocyclobutane may be harmful by asphyxiation. Exposure of the container to prolonged heat or fire can cause Octafluorocyclobutane to rupture violently and rocket. Octafluorocyclobutane is used to make other chemicals.

Reaktivität anzeigen

Octafluorocyclobutane is chemically inert in many situations, but can react violently with strong reducing agents such as the very active metals and the active metals. They suffer oxidation with strong oxidizing agents and under extremes of temperature.

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

Mdly toxic by ingestion and inhalation. Can cause slight transient effects at high concentrations. No anesthesia or central nervous system effects. Nonflammable gas. Mutation data reported. When heated to decomposition it emits hghly toxic fumes of F-.

mögliche Exposition

This material is used as a refrigerant.

Versand/Shipping

UN1976 octafluorocyclobutane, or refrigerant gas RC-318, Hazard class: 2.2; Labels: 2.2-Nonflammable compressed gas. Cylinders must be transported in a secure upright position, in a well-ventilated 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.

läuterung methode

Purify octafluorocyclobutane by trap-to-trap distillation, retaining the middle portion. [Danus Ind Eng Chem 47 144 1955, Claasen J Chem Phys 18 543 1950, Beilstein 5 III 8, 5 IV 8.]

Inkompatibilitäten

Octafluorocyclobutane is chemically inert in many situations, but can react violently with strong reducing agents such as hydrides and the active metals and especially the very active metals. They suffer oxidation with strong oxidizing agents and under extremes of temperature.

Waste disposal

Return refillable compressed gas cylinders to supplier. Nonrefillable cylinders should be disposed of in accordance with local, state and federal regulations. Allow remaining gas to vent slowly into atmosphere in an unconfined area or exhaust hood. Refillabletype cylinders should be returned to original supplier with any valve caps and outlet plugs secured and valve protection caps in place.
