WebA copper-mediated cross-coupling reaction between HCFC-123 and phenols or thiophenols has been achieved. It is found that diethyl amine, which serves as both the activator and ligand of copper, plays a key role in this reaction. Two possible radical involved processes are proposed for the reaction mechanism. Supporting Information Web一站式科研服务平台. 学术工具. 文档翻译; 收录引证; 论文查重; 文档转换

WebChemical and Physical properties: HCFC-123 is colorless, odorless liquid, stable in normal condition. Note: Isomers are 1,2-dichloro-1,1,2-trifluoroethane (R-123a) [354-23-4] and 1,1-dichloro-1,2,2-trifluoroethane (R-123b) [812-04-4] ... and can be produced for use in service until 2040. HCFC-123 is also used in large tonnage centrifugal ... 2,2-Dichloro-1,1,1-trifluoroethane or HCFC-123 is considered as an alternative to CFC-11 in low pressure refrigeration and HVAC systems, and should not be used in foam blowing processes or solvent applications. It is also the primary component of the Halotron I fire-extinguishing mixture. Its ozone depletion potential is ODP = 0.012, and global warming potential is G… WebProduct Description. hcfc-123 chemical fire extinguisher are packed in tremendous power and are ideal of protection of high value and sensitive equipment. •clean agent chemical … coopersofstortford-co-uk discount code
