355-08-8 Usage
Uses
Used in Refrigeration Industry:
1H,1H,2H-Heptafluoropent-1-ene is used as a refrigerant in various cooling systems due to its low ozone depletion potential and relatively low global warming potential. It serves as an environmentally friendly alternative to traditional refrigerants that have a higher impact on the ozone layer and climate change.
Used in Foam Insulation and Packaging Materials Industry:
1H,1H,2H-Heptafluoropent-1-ene is used as a blowing agent in the production of foam insulation and packaging materials. Its role is to create the foam structure by expanding the material, providing insulation and cushioning properties. The use of 1H,1H,2H-HEPTAFLUOROPENT-1-ENE in this industry is due to its ability to create stable and efficient foams with reduced environmental impact compared to other blowing agents.
However, it is important to note that the use of 1H,1H,2H-Heptafluoropent-1-ene is being regulated and phased out in many countries due to its classification as a greenhouse gas and its contribution to climate change. This has led to the search for more environmentally friendly alternatives in both the refrigeration and foam insulation industries.
Check Digit Verification of cas no
The CAS Registry Mumber 355-08-8 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, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 355-08:
(5*3)+(4*5)+(3*5)+(2*0)+(1*8)=58
58 % 10 = 8
So 355-08-8 is a valid CAS Registry Number.

Fluoroolefin condensation catalyzed by aluminum chlorofluoride
Krespan, Carl G.,Dixon, David A.
, p. 117 - 126 (2007/10/03)
High-fluorine-content aluminum chlorofluoride, as prepared by Cl/F exchange of aluminum chloride with one of a number of organofluorine compounds, is a very active Lewis acid capable of condensing an allylic fluoride with another fluoroolefin at low temperature. In addition to a description of broader scope, details of the selective reaction of hexafluoropropene with tetrafluoroethylene to form F-pentene-2 are presented along with evidence supporting polyfluoroallyl cationic species as intermediates. Ab initio calculations confirm the feasibility of the proposed mechanism and further suggest that 1,3-fluorine shifts in fluorocarbocations are energetically accessible at modest temperatures. Revised heats of formation for C3F8 (ΔH0f = - 1750 ± 12.4 kJ mol-1) and HFP (ΔH0f = - 1128 ± 5 kJ mol-1) have been calculated. Fluoride affinities of some simple metallohalogens are reported.
