Containers fluorocarbon

They show good to excellent resistance to highly aromatic solvents, polar solvents, water and salt solutions, aqueous acids, dilute alkaline solutions, oxidative environments, amines, and methyl alcohol. Care must be taken in choice of proper gum and compound. Hexafluoropropylene-containing polymers are not recommended for use in contact with ammonia, strong caustic (50% sodium hydroxide above 70°C), and certain polar solvents such as methyl ethyl ketone and low molecular weight esters. However, perfluoroelastomers can withstand these fluids. Propylene-containing fluorocarbon polymers can tolerate strong caustic.

Examples of successful fluorination syntheses accomplished in the solid state include the fluorination of polymers7 9, see Table 2 and formation of 2, 4 and 6, and the synthesis of per-fluoroethers and many other oxygen containing fluorocarbon compounds10-12 e.g. 7, 8, and 9 see also Figure 2. 

Aerosols Sprays containing propellants and solvents. In the United States, spray paints contain butane and propane (aliphatic hydrocarbons), fluorocarbon, hydrocarbons, and toluene hair sprays and air fresheners contain butane, propane, and fluorocarbon aerosol spray topical pain relievers and asthma sprays contain fluorocarbon. 

It has been reported (Wagner et al., 2000a) that GD (neat) does not react with gaseous ozone even after 1 h exposure. This is in contrast to the report of oxidation that was conducted using ozone-containing fluorocarbons (Snelson et al., 1986). Photochemical reactions in sunlight do not appear to be important for soman. 

In certain cases, 1,3-dipoles containing fluorocarbon groups will participate in cycloadditions to unsaturated hydrocarbons (Scheme 18143 and Eqs. 38144 and 39145 147). The reaction of the nitroalkane derivative 57 probably involves the nitrile oxide 58 as intermediate, since the furoxan product (59) corresponds to a dimer.144 Furoxans have also been obtained...

Perov and Nikolaev have reviewed advances in fluorine calorimetry French workers have described several bomb calorimeters suitable for use with F2 or with other fluorinating agents. By way of contrast, Lagow et al have applied their techniques of direct fluorination to N-containing organic compounds, and they were able to report the synthesis, in modest yield, of the corresponding N-containing fluorocarbon. 

Microemulsions containing fluorocarbons have been investigated as blood substitutes. For example, Cecutti et al. [55] studied these aspects of microemulsions and found that although the inherent incompatibility between hydrocarbons and fluorocarbons puts some demands on the surfactant to be used, the resulting microemulsion (prepared from fluorinated oil, water, and an nonionic surfactant) displayed oxygen absorption similar to that of blood, and at the same time the toxicity was limited and the microemulsions appeared to be well tolerated. 

Hildebrand and his co-workers have produced accurate gas solubilities for a great variety of systems over a lengthy period, and many of their measurements are tabulated in the comprehensive review of Battino and Clever. They have, however, persisted in the use of solubility parameter theory to correlate and interpret their measurements and in much of this work systems containing fluorocarbons either as the gaseous solute or as the liquid solvent appear to behave anomalously when compared with most other mixtures composed of non-polar molecules.
