Chemical Properties
colourless liquid
General Description
Clear colorless liquid.
Air & Water Reactions
Water soluble.
Reactivity Profile
A halogenated ketone. Ketones are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4.
Fire Hazard
Flash point data for HEXAFLUOROACETONE SESQUIHYDRATE are not available, however, HEXAFLUOROACETONE SESQUIHYDRATE is probably combustible.
Potential Exposure
Hexafluoroacetone is used as a chemi cal intermediate. A gas at room temperature, it forms vari ous hydrates with water which are used as solvents for
resins and polymers. Other derivatives are used to make
water repellent coatings for textiles and also to produce
polymers.
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, includ ing 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 medi cal attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit.
Medical observation is recommended for 24 to 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. If frostbite has occurred, seek
medical attention immediately; do NOT rub the affected
areas or flush them with water. In order to prevent further
tissue damage, do NOT attempt to remove frozen clothing
from frostbitten areas. If frostbite has NOT occurred, imme diately and thoroughly wash contaminated skin with soap
and water.
Shipping
UN2420 Hexafluoroacetone, Hazard Class: 2.3;
Labels: 2.3-Poisonous gas, 8-Corrosive material, Inhalation
Hazard Zone B. 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 com pressed 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 cylin ders without the express written permission of the owner.
Incompatibilities
Reacts with water, oxidizers, strong
acids. Hygroscopic (i.e., absorbs moisture from the air);
reacts with moisture to form a highly acidic sesquihydrate
and considerable heat.
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.
Refillable-type cylinders should be returned to original sup plier with any valve caps and outlet plugs secured and
valve protection caps in place.
reaction suitability
reagent type: oxidant
