Fluoroform, or trifluoromethane, is the chemical compound with the formula CHF3. It is a hydrofluorocarbon as well as being a part of the haloforms, a class of compounds with the formula CHX3 (X = halogen) with C 3v symmetry. Fluoroform is used in diverse applications in organic synthesis. It is not an ozone depleter but is a greenhouse gas. [2]

Jul 13, 2017 · We present a strategy to rationally prepare CF 3– transfer reagents at ambient temperature from HCF 3. We demonstrate that a highly reactive CF 3– adduct can be synthesized from alkali metal hydride, HCF 3, and borazine Lewis acids in …

Trifluoromethane is a colorless nonflammable gas. It is shipped as a liquid under pressure. It may be narcotic in high concentrations.

The team will publish their discovery in a paper entitled “Taming of Fluoroform (CF3H): Direct Nucleophilic Trifluoromethylation of Si, B, S and C Centers,” in the Dec. 7 issue of Science. The method is also being patented.

Feb 15, 2025 · Trifluoromethane (CF 3 H) is a potent greenhouse gas with a GWP of 14,600 (IPCC, 2021). The possible formation of CF 3 H in the photolysis of trifluoroacetaldehyde (CF 3 CHO) has been a topic of debate.

Jan 14, 2022 · New experimental work, published in 2022, demonstrates that HFC-23 (CF 3 H) is NOT formed during the decomposition of HFOs and HCFOs in the troposphere. This supports earlier work, including from 2006, that CF 3 H formation from …

Mar 3, 2023 · Here, the authors report a strategy to generate and use the short-lived CF3- intermediate from stable CF3H gas via fast biphasic mixing in precisely customized flow dissolvers.

Jan 21, 2007 · The potential energy surfaces for the CF3H unimolecular dissociation reaction and reactions of CF3H with free radical OH and H were investigated at the B3LYP6-311++G(**) and QCISD(T)6-311++G(**) levels and by the G3B3 theory.

Jul 28, 1996 · The relative importance of introducing CF3H as a fire suppressant with the oxidizer or the fuel stream, and its chemical and thermal effects on the extinction condition of counterflow CO/air/H2 diffusion flames, are investigated both experimentally and numerically.

Top 10 species with enthalpies of formation correlated to the Δ f H° of CF3H (g) Please note: The correlation coefficients are obtained by renormalizing the off-diagonal elements of the covariance matrix by the corresponding variances.
