Usage

General Description

1-chloroheptadecafluorooctane is a compound that belongs to the class of perfluorinated alkyl substances (PFAS). It is a fluorocarbon compound with the chemical formula C8F17Cl, consisting of a chain of 8 carbon atoms with 17 fluorine atoms attached and one chlorine atom. This chemical is often used as a surfactant in various industrial and commercial applications, including in the production of non-stick coatings, lubricants, and fire-fighting foams. However, 1-chloroheptadecafluorooctane is also known to be a persistent environmental pollutant, as it does not readily degrade in the environment and can accumulate in organisms, leading to potential health and environmental concerns. Due to its potential harmful effects, there is increasing regulatory attention towards limiting the use and environmental release of 1-chloroheptadecafluorooctane and other PFAS compounds.

Reactivite par voie thermique de RFH

Hydroperfluoroalkanes are well known as being rather inert chemically.Hydroperfluoroalkanes react at high temperature with carbon tetrabromide and carbon tetrachloride to yield bromoperfluoroalkanes and chloroperfluoroalkanes. - Keywords: Hydroperfluoroalkanes; High-temperature reaction; Carbon tetrabromide; Carbon tetrachloride; Bromoperfluoroalkanes; Chloroperfluoroalkanes

A Lewis acid catalytic process for preparing fluorocarboxylic acid halides

Selected Group III and Group V Lewis acids were found to catalyze the isomerization and rearrangement of halosulfonyldifluoromethyl group (Rf-CF2SO2X, where X is either chlorine or fluorine) to form fluorocarboxylic acid halides (RfCOX). Fluorodesulfoxylation of the halosulfonyldifluoromethyl group yielded SOF2 as one of the two sulfur-containing oxides. Product analysis would suggest that both Lewis acid catalyzed and halogen exchange reactions are occurring and are dependent upon the starting halosulfonyldifluoromethyl material and Lewis acid.

Chlorotrifluoroethylene-derived fluids. I. Model compound synthesis

A series of chlorofluoroalkanes having chlorines on adjacent carbon atoms has been prepared, i.e. n-C5F11CFClCCl3, n-C6F13CFClCCl3, n-C5F11CFClCFCl2, n-C6F13CFClCFCl2, n-C5F11CFClCF2Cl, n-C2F5CFClCFClC3F7 and n-CF3CFClCFClC4F9, by a combination of halogen exchange, dehalogenation and chlorine addition reactions.An attempt to synthesize n-C6F13CFClCF2CFCl2 by the coupling of n-C6F13CFClI with an excess of ICF2CFCl2 under UV radiation in the presence of Hg gave only n-C6F13CFClCFClC6F13 together with CFCl2CF2CF2CFCl2.Under parallel conditions from n-C6F13CFClI and CF2ClCFClI, n-C6F13CFClCFClCF2Cl was obtained in 48percent yield.
