355-42-0 Usage
Chemical Properties
colourless liquid
Uses
Different sources of media describe the Uses of 355-42-0 differently. You can refer to the following data:
1. In the electronics industry as a coolant and test bath medium. Non-toxic, non-ozone-depleting, inert reaction medium.
2. Perfluorohexanes is used as a coolant, photosensitizer in fluorous biphasic singlet oxygenation and an inert reaction medium. It is used in the electronic cooling liquid and insulator. It plays a vital role as a reaction medium, especially for photooxidation reactions. Further, it finds application as an ultrasound contrast agent.
3. Tetradecafluorohexane has been used:as a fluorocarbon organic solvent in the preparation of temperature-induced phase-separation solutionto investigate boiling heat transfer mechanisms as a photosensitizer in fluorous biphasic singlet oxygenation as a novel reaction medium for photooxidation reactions
Application
Perfluorohexane uses and applications include: dispersant for lubricants, mold release agents, protective coatings; reaction media for polymerizations, purification, separation processes; solvent for removal of halogenated lubricants, oils, greases; carrier for halogenated material; for quick-cooling or freezing foods; heat-transfer fluid.
Because it is biologically inert and chemically stable, perfluorohexane has attracted attention in medicine. Like other fluorocarbons, perfluorohexane dissolves gases, including oxygen from the air, to a higher concentration than ordinary organic solvents. This effect is attributed to the weak intermolecular forces between perfluorohexane molecules, which allows "space" for gas molecules to partition into the liquid. Animals can be submerged in a bath of perfluorohexane without drowning, as there is sufficient oxygen available in the solvent to allow respiration to continue. This effect has led to the experimental use of perfluorohexane in treating burn victims, as their lungs can be filled with either perfluorohexane vapor or in extreme cases liquid perfluorohexane, allowing breathing to continue without the problems normally seen with pulmonary edema that sometimes occur when the inside of the lungs have been burnt e.g. by inhalation of hot smoke.
General Description
Tetradecafluorohexane in the gas phase reacts spontaneously with lithium amalgam, to give a solid and intimate mixture of lithium fluoride and elemental polymeric carbon with a small amount of superstoichiometric lithium.
Purification Methods
Purify the fluorohexane by fractional freezing. The methods described for perfluoroheptane should be applicable here. [Beilstein 1 IV 348.]
Check Digit Verification of cas no
The CAS Registry Mumber 355-42-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,5 and 5 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 355-42:
(5*3)+(4*5)+(3*5)+(2*4)+(1*2)=60
60 % 10 = 0
So 355-42-0 is a valid CAS Registry Number.
