462-39-5 Usage
Uses
Used in Refrigeration Industry:
1,3-Difluoropropane is used as a refrigerant for its thermodynamic properties that make it suitable for cooling systems. It is valued for its ability to provide efficient cooling without causing harm to the ozone layer, unlike some other refrigerants.
Used in Foam Insulation and Packaging Materials Production:
1,3-Difluoropropane serves as a blowing agent in the manufacturing of foam insulation and packaging materials. Its role is to create the cellular structure of the foam, providing insulation and cushioning properties.
Used in Aerosol Products:
As a propellant, 1,3-Difluoropropane is used in aerosol products to eject substances such as spray paints, deodorants, and other sprayable consumer goods. Its properties allow for effective dispensing of these products.
Used in Cleaning and Degreasing Applications:
1,3-Difluoropropane functions as a solvent in cleaning and degreasing processes, particularly in industrial settings. It is capable of dissolving various types of dirt, grease, and oils, making it useful for maintenance and part cleaning.
Environmental Considerations:
Despite its utility, 1,3-Difluoropropane is recognized as a greenhouse gas, which has led to restrictions on its use in certain countries due to concerns about its environmental impact and contribution to global warming. This has spurred the search for alternative compounds with lower environmental footprints for the same applications.
Check Digit Verification of cas no
The CAS Registry Mumber 462-39-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,6 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 462-39:
(5*4)+(4*6)+(3*2)+(2*3)+(1*9)=65
65 % 10 = 5
So 462-39-5 is a valid CAS Registry Number.

Reaction of diethylaminosulfur trifluoride with diols
Shellhamer, Dale F.,Anstine, D. Timothy,Gallego, Kelly M.,Ganesh, Brian R.,Hanson, Aaron A.,et al.

Diethylaminosulfur trifluoride (DAST) reacts with dialcohols to give difluorides, sulfite esters or cyclic ethers depending on the number of carbons separating the two alcohol groups.Vicinal and 1,3-diols give large amounts of sulfite ester products while butane-1,4-diol gives almost exclusively the cyclic ether tetrahydrofuran.Terminal dialcohols longer than four carbons give primarily difluoride products.Semiempirical calculations indicate a preference for cyclic intermediates when four or less carbons separate the two alcohol moieties.These cyclic intermediates lead directly to the cyclic ethers and sulfite ester products.
