| Hazard Information | Back Directory | [General Description]
OCTAFLUOROCYCLOBUTANE(115-25-3) is a colorless nonflammable gas. OCTAFLUOROCYCLOBUTANE(115-25-3) may be harmful by asphyxiation. Exposure of the container to prolonged heat or fire can cause OCTAFLUOROCYCLOBUTANE(115-25-3) to rupture violently and rocket. OCTAFLUOROCYCLOBUTANE(115-25-3) is used to make other chemicals. | [Reactivity Profile]
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. | [Potential Exposure]
This material is used as a refrigerant. | [Fire Hazard]
Some may burn but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including
resuscitation mask), if breathing has stopped and CPR if heart
action has stopped. Transfer promptly to a medical facility.
When this chemical has been swallowed, get medical attention.
Give large quantities of water and induce vomiting.
Do not make an unconscious person vomit. Medical observation
is recommended for 24－48 hours after breathing overexposure,
as pulmonary edema may be delayed. As first aid for
pulmonary edema, a doctor or authorized paramedic may consider
administering a drug or other inhalation therapy. | [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. | [Incompatibilities]
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. | [Description]
Octafluorocyclobutane is a colorless gas.Molecular weight = 200.03; Boiling point = -6℃;Freezing/Melting point = -41℃. Hazard Identification(based on NFPA-704 M Rating System): Health 2,Flammability 0, Reactivity 0. Slightly soluble (slighthydrolysis). | [Chemical Properties]
Colorless and tasteless liquefied gas | [Chemical Properties]
Octafluorocyclobutane is a colorless gas. | [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. | [Uses]
Refrigerant; heat-transfer medium. | [Definition]
ChEBI: A fluorocarbon that is cyclobutane in which all eight hydrogens are replaced by fluorines. | [storage]
Color Code—Green: General storage may be used.Prior to working with this chemical you should be trainedon its proper handling and storage. Store in tightly closedcontainers in a cool, well-ventilated area away from potential high heat sources. Protect cylinders from physical damage. Procedures for the handling, use, and storage ofcylinders should be in compliance with OSHA 1910.101and 1910.169, as with the recommendations of theCompressed Gas Association. | [Purification Methods]
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.] |
