PRODUCTION OF THE FLUORINE-CONTAINING COMPOUNDS Russian patent published in 2006 - IPC C07B39/00 C07C67/307 C07C69/63 C01B17/45 C07D487/04 C07D213/74 C07C17/20 

FIELD: chemical industry; method of production of the fluorine-containing compounds.

SUBSTANCE: the invention is pertaining to the chemical industry, in particular, to the improved method of production of fluorine-containing compounds from the halogen-containing, compounds, preferably, from chlorine-containing compounds due to an exchange of halogen for fluorine at presence of the HF-additional compound of the mono- or bicyclic amine with at least two atoms of nitrogen. At that at least one atom of nitrogen is built in the cyclic system as the fluorating agent; or at presence of anhydrous hydrogen fluoride - as the fluorating agent and the indicated HF-additional compound of the mono- or bicyclic amine as the catalyst. At usage of the applicable solvents the reaction mixtures can be divided into two phases and thus to simplify the reprocessing of the products. The invention also is pertaining to the HF-additional compounds of 1.5-diazabicyclo[4.3.0]non-5-en and N,N-dialkylaminopiridin, where alkyl represents C₁-C₄alkyl and where the molar ratio of HF to amine makes 1:1, and to HF- additional compounds 1.8- diazabicyclo[5.4.0]undecyl-7-ene, where the molar ratio of HF to amine compounds more than 1:1.

EFFECT: the invention ensures at usage of the applicable solvents to divide the reaction mixture into two phases and thus to simplify reprocessing of the products.
