Dehalogenation of Trichlorofluoromethane (CFC‐11) by Methanosarcina barkeri
FEMS Microbiology Letters, 1992Co-Authors: Ute E. Krone, Rudolf K. ThauerAbstract:Methanobacterium barkeri was found to catalyze the reductive dehalogenation of Trichlorofluoromethane (CFC-11), also known as FREON 11. Products detected were CHFCI2, CH2FCI, CO and fluoride.

Ultrasonic speed for liquid Trichlorofluoromethane and 1,1-dichloro-2,2,2-trifluoroethane at temperatures from 283 to 373 K and pressures up to 75 MPa
Journal of Chemical & Engineering Data, 1991Co-Authors: Toshiharu TakagiAbstract:The ultrasonic speeds for liquid Trichlorofluoromethane (CCl 3 F) and 1,1-dichloro-2,2,2-trifluoroethane (C 2 HCl 2 F 3 ) were measured from 283 to 373 K and from 0.1 MPa or their saturated vapor pressure to about 75 MPa. The measurements were carried out by a sing-around technique operated at a frequency of 2 MHz with the uncertainly of ±0.2%. The temperature and pressure variation of ultrasonic speed and related properties are discussed

Experimental P-T-ρ and enthalpy-increment measurements of an equimolar mixture of Trichlorofluoromethane (R-11) + chlorotrifluoromethane (R-13)
Journal of Chemical & Engineering Data, 2003Co-Authors: Gustavo A. Iglesias-silva, R. C. Castro-gomez, William J. Rogers, And James C. Holste, Kenneth R HallAbstract:We have measured experimental liquid densities and enthalpy increments for an equimolar mixture of Trichlorofluoromethane (R-11) + dichlorodifluoromethane (R-12). We have used a continuously weighed pycnometer for measuring the liquid densities and a thermoelectric flow calorimeter for measuring the enthalpy increments. The temperature range for all measurements is from (230 to 425) K. The experimental measurements range up to 69 MPa with the pycnometer and 6.8 MPa with the calorimeter, respectively.

experimental densities of Trichlorofluoromethane r 11 and chlorodifluoromethane r 22 at 270 k and up to 67 mpa
Journal of Chemical & Engineering Data, 1995Co-Authors: Gustavo A Iglesiassilva, Kenneth R Hall, James C. HolsteAbstract:The authors have used a continuously weighed pycnometer to measure compressed liquid densities of Trichlorofluoromethane (R-11) and chlorodifluoromethane (R-22) at 270 K and pressures to 67 MPa. The precision of the liquid density measurements is better than {+-}0.1 kg/m{sup 3}, and the accuracy is {+-}0.08% at the 95% confidence limit. The new results agree within the combined uncertainties with published measurements in regions of overlap, and they show that existing equations of state extrapolate well to higher pressures.

A Novel Approach to 2‐Chloro‐2‐fluorostyrenes
European Journal of Organic Chemistry, 2003Co-Authors: Valentine G. Nenajdenko, Alexey V. Shastin, V. N. Korotchenko, Georgy N. Varseev, Elisabeth S. BalenkovaAbstract:A new general catalytic olefination reaction (COR) of aromatic and heteroaromatic aldehydes and ketones was applied to synthesise 2-chloro-2-fluorostyrenes. The two-stage procedure includes the transformation of carbonyl compounds into hydrazones followed by treatment with CFCl3 mediated by copper catalysis. Trichlorofluoromethane was used as a chlorofluoromethylene transfer reagent. The reaction proceeds stereoselectively and the target alkenes were obtained in high yield. A proposed mechanism for the reaction is discussed. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
