3175-25-5 Usage
General Description
HCFC-241bb is a hydrochlorofluorocarbon chemical compound used primarily as a blowing agent in the production of foam insulation. It is recognized as an ozone-depleting substance and is being phased out globally under the Montreal Protocol due to its significant impact on the Earth's ozone layer. HCFC-241bb has a high global warming potential, making it a contributing factor to climate change. Its production, use, and release into the atmosphere are strictly regulated to mitigate its harmful effects on the environment and human health. Research and development are ongoing to find suitable alternatives to HCFC-241bb that are more environmentally friendly and sustainable for various industrial applications.
Check Digit Verification of cas no
The CAS Registry Mumber 3175-25-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,7 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3175-25:
(6*3)+(5*1)+(4*7)+(3*5)+(2*2)+(1*5)=75
75 % 10 = 5
So 3175-25-5 is a valid CAS Registry Number.

PROCESSES FOR PRODUCING 2-CHLORO-1,1,1,2-TETRAFLUOROPROPANE AND 2,3,3,3-TETRAFLUOROPROPENE
-
Page/Page column 5, (2011/10/12)
To provide processes for efficiently and economically producing 2-chloro-1,1,1,2-tetrafluoropropane (R244bb) and 2,3,3,3-tetrafluoropropene (R1234yf) in an industrially practical manner. A process for producing 2-chloro-1,1,1,2-tetrafluoropropane, which comprises a chlorination step of reacting 1,2-dichloro-2-fluoropropane and chlorine in the presence of a solvent under irradiation with light to obtain 1,1,1,2-tetrachloro-2-fluoropropane, and a fluorination step of reacting the 1,1,1,2-tetrachloro-2-fluoropropane obtained in the chlorination step and hydrogen fluoride in the presence of a catalyst to obtain 2-chloro-1,1,1,2-tetrafluoropropane, and a process for producing 2,3,3,3-tetrafluoropropene, which comprises dehydrochlorinating it in the presence of a catalyst.
