General Description
DECAFLUOROPENT-2-ENE is a colorless, odorless, and highly reactive chemical compound with the molecular formula C5F10. It is a member of the perfluorocarbon family and is used as a refrigerant, solvent, and electrical insulator. DECAFLUOROPENT-2-ENE is non-flammable and has a high dielectric strength, making it suitable for use in electrical components and as a heat transfer medium. However, it is also a potent greenhouse gas with a high global warming potential, and its use is regulated under the Kyoto Protocol and the Paris Agreement. Furthermore, it is important to handle DECAFLUOROPENT-2-ENE with caution as it can cause skin and eye irritation and may be harmful if inhaled or ingested.
Check Digit Verification of cas no
The CAS Registry Mumber 72804-49-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,8,0 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 72804-49:
(7*7)+(6*2)+(5*8)+(4*0)+(3*4)+(2*4)+(1*9)=130
130 % 10 = 0
So 72804-49-0 is a valid CAS Registry Number.

Disclosed is a process comprising reacting CF3CF2CCI2CF2CF3 (CFC-41 -10mca) with hydrogen in the presence of a dehalogenation catalyst to produce CF3CF2CCI=CFCF3 (CFC-1419myx). Also disclosed herein is a process comprising reacting CF3CF2CCI=CFCF3 (CFC- 1419myx) with hydrogen in the presence of a dehalogenation catalyst to produce CF3CF2C≡CCF3 (octafluoro-2-pentyne). Also disclosed herein is a process comprising reacting CF3CF2CCI2CF2CF3 (CFC-41 -10mca) with hydrogen in the presence of a dehalogenation catalyst to produce CF3CF2C≡CCF3 (octafluoro-2-pentyne). In addition, a process for reacting CF3CF2C≡CCF3, in a pressure vessel, with a Lindlar catalyst and hydrogen to produce CF3CF2CH=CHCF3 (1,1,1,4,4,5,5,5-octafluoro-2- pentene) is disclosed.
