Uses
Used in Refrigeration Industry:
1-Chloro-1,2-difluoroethane is used as a refrigerant for cooling systems in various applications, such as air conditioning and refrigeration equipment, due to its thermodynamic properties and compatibility with existing systems.
Used in Foam Blowing Agents Industry:
1-Chloro-1,2-difluoroethane is used as a foam-blowing agent for the production of insulation materials, packaging materials, and automotive components. Its ability to create stable and lightweight foams makes it suitable for these applications.
Used in Cleaning and Degreasing Applications:
1-Chloro-1,2-difluoroethane is used as a solvent for cleaning and degreasing purposes in various industries, such as electronics manufacturing and metalworking. Its ability to dissolve oils and greases effectively makes it a valuable cleaning agent.
Used in Aerosol Products Industry:
1-Chloro-1,2-difluoroethane is used as a propellant in aerosol products, such as spray paints, deodorants, and other consumer goods. Its ability to provide a consistent and controlled release of the product makes it suitable for these applications.
However, due to its ozone-depleting properties, 1-Chloro-1,2-difluoroethane is being phased out under the Montreal Protocol, and more environmentally friendly alternatives are being developed and adopted. It is crucial to handle and use this chemical with caution, as it can be harmful if inhaled or exposed to skin and eyes.
Check Digit Verification of cas no
The CAS Registry Mumber 338-64-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,3 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 338-64:
(5*3)+(4*3)+(3*8)+(2*6)+(1*4)=67
67 % 10 = 7
So 338-64-7 is a valid CAS Registry Number.

The chlorination of 1,2-difluoroethane (HFC-152)
Nappa, Mario J.,Sievert, Allen C.
, p. 111 - 118 (2007/10/02)
The photochlorination of CH2FCH2F yields CH2FCCl2F and CHClFCHClF, both of which were considered to be potential replacements for CFC-113 (CCl2FCF2Cl) based on their boiling points (48 deg C and 59 deg C, respectively).The CHClFCHClF/CH2FCCl2F ratio can be controlled by the choice of solvents.In aromatic solvents, the reactivity of the chlorine radical is reduced, increasing the amount of CH2FCCl2F produced.Relative rates in CCl4 and in the presence of water were compared to rates in aromatic solvents.Both CH2FCCl2F and CHClFCHClF failed in early toxicity tests and will thus not be pursued as HCFC replacements for CFC-113.
