General Description
PERFLUOROISONONYL IODIDE is a synthetic chemical compound that belongs to the perfluoroalkyl iodides family. It is a colorless, odorless liquid with a high boiling point and low vapor pressure, making it useful for various industrial applications. As a fluorinated compound, it is known for its hydrophobic and oleophobic properties, making it suitable for use as a surface treatment agent to impart water and oil repellency to various materials. It is also used as a building block in the production of specialty chemicals, such as surfactants, lubricants, and polymers. However, the use of PERFLUOROISONONYL IODIDE has raised environmental and health concerns due to its persistence and potential toxicity. Efforts are being made to find safer alternatives and to regulate its use to minimize its impact on the environment and human health.
Check Digit Verification of cas no
The CAS Registry Mumber 865-77-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,6 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 865-77:
(5*8)+(4*6)+(3*5)+(2*7)+(1*7)=100
100 % 10 = 0
So 865-77-0 is a valid CAS Registry Number.

Synthesis of telogens and optimization of tetrafluoroethene telomerization process
Lewandowski, Grzegorz,Meissner, Egbert,Milchert, Eugeniusz
, p. 337 - 344 (2007/10/03)
The most advantageous technological parameters of tetrafluoroethene telomerization using 1-chloro-2-iodohexafluoropropane (telogen) towards the telomers n2-n4 or n1-n4 were experimentally established. The telomers n1-n4 were prepared with the yield of 48 mol% under the following conditions: temperature 170°C, the molar ratio of 1-chloro-2-iodohexafluoropropane to tetrafluoroethene equal to 1.2, the autoclave filling of 1.5 kg dm-3. The maximum yield of telomers n2-n4 amounted to 27 mol% when the molar ratio of telogen to tetrafluoroethene was decreased to 0.7 and the other parameters of synthesis remained the same. The optimum parameters for the synthesis of telogens: 1-chloro-2-iodohexafluoropropane and 2-iodoheptafluoropropane have been also determined.
