General Description
2,2-BIS(4-ISOCYANATOPHENYL)HEXAFLUOROPROPANE, also known as bis(4-isocyanatophenyl)hexafluoropropane or PTFIC, is a chemical compound that consists of two isocyanate functional groups attached to a hexafluoropropane backbone. It is commonly used in the production of high-performance polymers, such as polyurethanes and polyurea coatings, due to its exceptional thermal stability and resistance to solvents and chemicals. PTFIC is also used as a building block in the synthesis of specialty chemicals and materials, and it is known for its low toxicity and relatively low volatility compared to other isocyanates. However, proper handling and safety precautions must be taken when working with this compound due to its potential to cause skin and respiratory irritation.
Check Digit Verification of cas no
The CAS Registry Mumber 10224-18-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,2 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 10224-18:
(7*1)+(6*0)+(5*2)+(4*2)+(3*4)+(2*1)+(1*8)=47
47 % 10 = 7
So 10224-18-7 is a valid CAS Registry Number.

Method for preparing isocyanate by using amine and carbonyl fluoride
-
, (2017/07/07)
The invention discloses an efficient synthesis method for preparing corresponding isocyanate by enabling carbonyl fluoride to directly react with amine. The efficient synthesis method mainly comprises the following two steps: carrying out acylation reaction on the amine and the carbonyl fluoride according to a preferable proportion in an anhydrous inertial organic solvent under a sealed environment and a proper reaction condition, thus generating an intermediate-carbamyl fluoride; (2) carrying out dehydrofluorination on the intermediate-carbamyl fluoride under normal pressure and the proper reaction condition, thus obtaining the target isocyanate. During a reaction process, addition of a catalyst is not needed, the reaction conditions are mild, excessive carbonyl fluoride and a used solvent during the reaction process can be efficiently recycled and reused, and a by-product HF can be commercially sold after being collected and refined.
