General Description

1,1,1,3,3,3-Hexachloro-2,2-difluoro-propane, also known as HCDFP, is a chemical compound that belongs to the group of halogenated organic solvents. It is a colorless and odorless liquid that is primarily used as a solvent for cleaning and degreasing purposes. HCDFP is highly flammable and has been found to be damaging to the ozone layer. It is also known to be toxic to aquatic organisms and may cause long-term adverse effects in the environment. Due to its potential environmental and health hazards, the production and use of HCDFP are regulated in many countries.

Synthese des α,ω-dichlorures d'acide a chaines chlorofluorees par hydrolyse des α,ω-bis trichloromethyles correspondants

This paper describes the transformation of α,ω-bis(trichloromethyl) compounds into perhalogenated diacid chlorides.The general formulae of the starting products are CCl3-(CF2-CFCl)x-CF2-CCl3 (I,x) with x=0, 1, 2 and CCl3-CF2-CCl2-CF2-CCl3 (II).Hydrolysis, by oleum, of compounds (I,0) and (I, 2) leads to the corresponding diacid chlorides.Hydrolysis of (I, 1) and (II) however yields perhalogenated cyclic, sixmembered stable acid anhydrides.In the second part of this work, several methods are compared for synthesizing diacid chlorides from diacids or cyclic anhydride s prepared by the hydrolysis of (I, 1) and (II).We have found that of these the most interesting is the reaction between a perhalogenated diacid with 1,4-bis(trichloromethyl)benzene.The perhalogenated diacid chlorides are prepared with a minimum yield of 50percent.

SYNTHESE DE COMPOSES PHOSPHONIQUES A CHAINE CHLOROFLUOREE. PARTIE I

The Redox catalysis and free-radical telomerizations of di- and trichloromethylphosphonyl dichlorides and their esters with chlorotrifluoroethylene (CTFE) were studied.Also investigated was phosphonation of telomers of CTFE and carbon tetrachloride using Kinnear-Perren and Michaelis-Arbuzov methods.Phosphonic compounds containing chlorofluorinated blocks are obtained with these two methods.By-products are described and explained using known mechanisms.
