335-27-3 Usage
Description
PERFLUORO-1,3-DIMETHYLCYCLOHEXANE is a clear colorless liquid that has been studied for its properties, particularly in the quenching of the second excited singlet state of xanthione using picosecond time-resolved fluorescence decay methods.
Uses
Used in the Preparation of Amorphous Fluorocarbon Films:
PERFLUORO-1,3-DIMETHYLCYCLOHEXANE is used as a precursor for the preparation of amorphous fluorocarbon films by plasma polymerization. This application takes advantage of its chemical properties to create films with unique properties for various applications.
Used in Hydroformylation of Linear Terminal Alkenes:
PERFLUORO-1,3-DIMETHYLCYCLOHEXANE is used as a solvent in the hydroformylation of linear terminal alkenes using rhodium-based catalysts under fluorous biphasic conditions, both in the presence and absence of toluene. This application utilizes its inert and nonpolar nature to facilitate the reaction process and improve the efficiency of the hydroformylation.
Purification Methods
Fractionally distil it, then 35mL are sealed with about 7g KOH pellets in a borosilicate glass ampoule and heated at 135o for 48hours. The ampoule is cooled, opened, and the liquid is resealed with fresh KOH in another ampoule and heated as before. This process is repeated until no further decomposition is observed. The substance is then washed with distilled water, dried (CaSO4) and distilled. [Grafstein Anal Chem 26 523 1954, Beilstein 5 III 378.] IRRITANT.
Check Digit Verification of cas no
The CAS Registry Mumber 335-27-3 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 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 335-27:
(5*3)+(4*3)+(3*5)+(2*2)+(1*7)=53
53 % 10 = 3
So 335-27-3 is a valid CAS Registry Number.

DIRECT GAS-PHASE CATALYTIC FLUORINATION OF PARTIALLY FLUORINATED ORGANIC COMPOUNDS
Zakharov, V. Yu.,Denisov, A. K.,Novikova, M. D.
, p. 1942 - 1945 (2007/10/03)
The fluorination of a wide range of polyfluorinated organic compounds with molecular fluorine in the gas phase in a layer of NiF2/support as catalyst was investigated.It was shown that the selectivity of fluorination of the series of fluoroolefins, acid fluorides, polyfluoroalkanes, and hydrogen-containing ethers can be greatly increased.The developed method was used on an industrial scale in the production of perfluorinated liquids.
