828-35-3 Usage
General Description
1H,2H-Octafluorocyclopentane is a chemical substance, specifically a perfluorinated cycloalkane, with the molecular formula C5F8. It is known for its azeotropic properties and is often used for refrigeration and as a heat transfer fluid in certain applications due to its high performance and low environmental impact. The molecule exhibits characteristics of both alkane and perfluoroalkane, consistent with the hydrophilic-hydrophobic nature. Importantly, it is a non-ozone-depleting substance and is more environmentally friendly compared to traditional cooling agents. Despite being chemically stable, it does have a high global warming potential which warrants conscious and regulated usage.
Check Digit Verification of cas no
The CAS Registry Mumber 828-35-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 8 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 828-35:
(5*8)+(4*2)+(3*8)+(2*3)+(1*5)=83
83 % 10 = 3
So 828-35-3 is a valid CAS Registry Number.

Process for producing fluorinated alkene and fluorinated alkane
-
, (2008/06/13)
A vic-dichloro-fluorinated alkene of the formula: R1 --CCl=CCl--R2, and a fluorinated alkane of the formula: R1 --CR3 R4 --CR5 R6 --R2, wherein each of R1 and R2 independently represents a perfluoroalkyl group or both of R1 and R2 form together a perfluoroalkylene group, and R3, R4, R5 and R6 independently represent hydrogen or fluorine, are produced from an inexpensive raw material. More specifically, hexachlorocyclopentadiene is reacted with gaseous chlorine using an antimony catalyst, and then the reaction product is reacted with hydrogen fluoride to give 1,2-dichlorohexafluorocyclopentene. Thus-obtained compound is either (i) hydrogenated, or (ii) treated with a fluorinating agent to substitute the chlorine atoms by fluorine atoms, and then hydrogenated, to give the intended fluorinated alkane.
