Hexafluoroacetone is a colorless, nonflamma ble poison gas. Musty odor. Shipped as a liquefied com pressed gas.
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.
Flash point data for HEXAFLUOROACETONE SESQUIHYDRATE are not available, however, HEXAFLUOROACETONE SESQUIHYDRATE is probably combustible.
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.
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.
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.
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.
