Reactivity Profile

Ketones, such as BIS(HEPTAFLUOROISOPROPYL)KETONE, 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.

Preparation method of perfluoroketone

The invention discloses a preparation method of perfluoroketone. According to the preparation method, in an organic solvent, in the presence of a catalyst metal fluoride and a cosolvent, an addition reaction is performed on perfluoroolefin R1R2C=CR3R4 (R1, R2, R3 and R4 adopt a general formula of CnF2n+1 and n is a non-negative integer set) and acyl fluoride R5-COF (R5 adopts a general formula ofCmF2m+1 and m is a non-negative integer set) to obtain the perfluoroketone CFR3R4-CR1R2-COR5 (R5 is perfluoroalkyl) or CFR3R4-CR1R2-C(O)-CR1R2-CFR3R4 (R5 is an F atom). By the preparation method, theperfluoroolefins and the acyl fluoride are easy to obtain and low in price and the yield of perfluoroketone is high; a route is easy to industrialize.

A process for preparing acylfluorides

A process for preparing acylfluorides by reaction of carbonyl fluoride COF2 with compounds having general formula:T = CR1R2 wherein:T is O or CF2R1 and R2, equal or different, are F or a R(O)t radical, wherein R = linear or branched C1-C7 (per)fluoroalkyl, optionally containing one or more oxygen atoms, t is an integer equal to zero or 1; wherein a catalyst supported on porous compound is used, the catalyst being selected from: CsF, RbF, KF, AgF, each optionally in admixture with one or more of the others.
