FLUORINATED PEROXIDES AND SALTS

The peroxyhypochlorite is especially reactive, and the fluoroperoxy compounds produced by its interaction with haloalkenes can detonate when subjected to thermal or mechanical shock. However, no explosions were experienced during this work. See related FLUORINATED PEROXIDES AND SALTS, HYPOHALITES...

Oxidation of Salts from Ferulic and / -Fluoroferulic Acids. When stem sections were incubated with ferulic acid, isopropylamine or sodium salts, the cell walls of the youngest xylem or sclerenchyma elements were stained a light pink color. No reaction was observed in other cell walls (Table I). The same result was obtained with fluorinated analogues. The fact that only peroxidases from lignifying cell walls are able to oxidize ferulic compounds and syringaldazine must be emphasized. Absorption spectra of the pink oxidation products of ferulic acid and / -fluoroferulic acid in the presence of hydrogen peroxide and peroxidases extracted from tobacco cell walls ( covalently bound fraction) showed a peak at 520 nm.

One of the most efficient and simplest routes for the fabrication of these perfluorodioxolane monomers and polymers is shown in Scheme 4.3 [26-30]. Commercially available methyl pyruvate and diols are used as the starting materials. The condensation product is then directly fluorinated in a fluorinated solvent such as Fluorinert FC-75 (3M) with a F2/N2 mixture. After flushing the system with nitrogen gas for 1 h, fluorine gas diluted to 20% with nitrogen is blown into the reaction mixture at a flow rate of 2401/h. The reaction is carried out at approximately 25 C for over 20 h. After the reaction is complete, the mixture is neutralized with aqueous potassium hydroxide. The crude monomer is isolated upon decarboxylation of the potassium salt and then purified by fractional distillation. The fluorination process is the key step in the synthesis. The yield is as high as 75% with careful control of the fluorination temperature, and it depends on the structure of the hydrocarbon precursor. Recently, over 90% yield of the fluorination of similar compounds has been reported [31]. The polymerization of these monomers is generally carried out in bulk at 60 - 80 °C for 24-35 h using perfluorodibenzoyl peroxide as the initiator [32]. The conversion yields are 70-80%, and the polymers obtained are colorless and transparent. 

In the work conducted by Chandrasekaran, " initiators for solvent-based polymerization included aliphatic and aromatic peroxy compounds, including fluorine and chlorine substituted organic peroxides. Specific examples are acetyl peroxide, succinic acid peroxide, 2,4-dichlorobenzoyl peroxide, t-butylper-oxypivalate, decanoyl peroxide, trichloroacetyl peroxide, and perfluoropropionyl peroxide. Aqueous polymerization was conducted using persulfate, perphosphate and perborate salts of sodium, potassium.
