Propane, 1,2,2-trichloro-1,1,3,3-tetrafluoro-, also known as 1,1,3,3-tetrafluoro-2-(trifluoromethyl)propane or simply R-1234yf, is a hydrofluorocarbon (HFC) refrigerant with the chemical formula C3HF7Cl3. It is a colorless, odorless, and non-toxic gas that is used as a replacement for hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs) in various applications, such as automotive air conditioning, stationary air conditioning, and refrigeration systems. R-1234yf has a low global warming potential (GWP) of 4, which is significantly lower than other refrigerants, making it an environmentally friendly alternative. It is non-flammable and has a zero ozone depletion potential (ODP), contributing to its popularity as a more sustainable option in the refrigeration and air conditioning industry.

422-32-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 422-32-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 422-32:
(5*4)+(4*2)+(3*2)+(2*3)+(1*2)=42
42 % 10 = 2
So 422-32-2 is a valid CAS Registry Number.

PROCESS FOR REFINING HCFC-224ca AND/OR CFO-1213ya, PROCESS FOR PRODUCING HCFC-224ca, AND PROCESS FOR PRODUCING CFO-1213ya

-

Paragraph 0121, (2019/12/04)

PROBLEM TO BE SOLVED: To provide a process in which a difficult-to-separate HCFC-224ab can easily be removed and HCFC-224ca and/or CFO-1213ya can be produced with high purity and high yield. SOLUTION: Provided is a process for refining HCFC-224ca and/or CFO-1213ya, comprising a step of removing at least a portion of said HCFC-224ab from a mixture containing 1,1,3-trichloro-2,2,3,3-tetrafluoropropane (HCFC-224ca) and/or 1,1,3-trichloro-2,3,3-trifluoropropene (CFO-1213ya) and 1,2,2-trichloro-1,1,3,3-tetrafluoropropane (HCFC-224ab).

19F nuclear magnetic resonance studies of halogenated propanes

Tanuma, T.,Ohnishi, K.,Okamoto, H.,Miyajima, T.,Morikawa, S.

, p. 259 - 284 (2007/10/02)

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.
