HEXAFLUOROACETONE SESQUIHYDRATE Usage And Synthesis

Chemical Properties

colourless liquid

Chemical Properties

Hexafluoroacetone is a colorless, nonflamma ble poison gas. Musty odor. Shipped as a liquefied com pressed gas.

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.

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.
