13474-88-9 Usage
Description
1,1-Dichloro-1,2,2,3,3-pentafluoropropane is a colorless, odorless liquid that is nonflammable. It is a polyfluorinated compound, which makes it suitable for use as a refrigerant in cooling systems. However, it is also classified as an environmental toxin due to its contribution to ozone depletion.
Uses
Used in Cooling Systems:
1,1-Dichloro-1,2,2,3,3-pentafluoropropane is used as a refrigerant in cooling systems for its polyfluorinated properties, which provide efficient heat transfer and cooling capabilities. Its nonflammable nature also adds to its safety in these applications.
Used in Environmental Regulation:
1,1-Dichloro-1,2,2,3,3-pentafluoropropane is recognized as an environmental toxin and is listed on the US EPA Toxic Release Inventory (TRI) list. This classification highlights the need for regulation and monitoring of its use and release into the environment to minimize its impact on ozone depletion and overall environmental health.
Air & Water Reactions
Slightly soluble in water.
Reactivity Profile
1,1-dichloro-1,2,2,3,3-pentafluoro-propane is chemically inert in many situations, but can react violently with strong reducing agents such as the very active metals and the active metals. They suffer oxidation with strong oxidizing agents and under extremes of temperature.
Check Digit Verification of cas no
The CAS Registry Mumber 13474-88-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,7 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13474-88:
(7*1)+(6*3)+(5*4)+(4*7)+(3*4)+(2*8)+(1*8)=109
109 % 10 = 9
So 13474-88-9 is a valid CAS Registry Number.

, (2008/06/13)
A method of recovering pure dichloropentafluoropropane from a mixture of dichloropentaflouropropane and chloroform (including breaking the azeotropic mixture thereof) involving selectively fluorinating the chloroform to the lower boiling dichloromonofluoromethane and then distilling to separate and recover pure dichloropentafluoropropane.

The relationship between 19F chemical shifts in halogenated propanes and their structures are elucidated using MNDO calculations to determine the population of rotamers.The pairs of atom gauche to a fluorine atom and van der Waals interaction between the two terminal substituents are responsible for the 19F chemical shifts.The differences among chemical shifts in diastereomers are also discussed in terms of the conformation of molecule.
