PERFLUOROPROPANE Chemical Properties,Usage,Production

Uses

Ultrasound contrast imaging in cardiology and radiology (diagnostic).

Uses

Perfluoropropane is a non flammable greenhouse gas that is used in management of retinal tears in eye. It is also used in refrigeration mixtures.

Definition

ChEBI: Octafluoropropane is a fluorocarbon that is propane in which all of the hydrogens have been replaced by fluorines. It is a fluorocarbon and a fluoroalkane. It derives from a hydride of a propane.

brand name

Definity (Bristol-Myers Squibb).

General Description

PERFLUOROPROPANE is a colorless, odorless gas. PERFLUOROPROPANE is relatively inert. The mixture is nonflammable and nontoxic, though asphyxiation may occur because of displacement of oxygen. Exposure of the container to prolonged heat or fire can cause PERFLUOROPROPANE to rupture violently and rocket.

Reactivity Profile

PERFLUOROPROPANE 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.

Fire Hazard

Some may burn but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket.

Purification Methods

Purify it for pyrolysis studies by passage through a copper vessel containing CoF3 at about 270o, then fractionally distil it. [Steunenberg & Cady J Am Chem Soc 74 4165 1952.] Also purify it by several trap-to-trap distillations at low temperatures [Simons & Block J Am Chem Soc 59 1407 1937].
