Group 1 fluorides phosgene

A series of reactions with gases have been selected for the rapid quantification of many of the major products from the oxidation of polyolefins. Infrared spectroscopy is used to measure absorptions after gas treatments. The gases used and the groups quantified include phosgene to convert alcohols and hydroperoxides to chloroformates, diazomethane to convert acids and peracids to their respective methyl esters, sulfur tetrafluoride to convert acids to acid fluorides and nitric oxide to convert alcohols and hydroperoxides to nitrites and nitrates respectively. 

Although it will not be possible to dispense with some of these reagents entirely, their industrial use is likely to be confined to a small group of experts who are properly equipped to handle and contain these materials. In some cases, catalytic alternatives may provide an answer, such as the use of catalytic carbonylation instead of phosgene and solid acids as substitutes for hydrogen fluoride.

Due to the fact that, especially in the first moments of oxidation, the amounts of oxygen containing groups or products is very low, their identification by the above-mentioned methods is difficult. For detailed studies, Carlsson et al. [116] proposed FTIR techniques of great sensitivity, recorded after some derivatization reactions these have been accomplished by means of phosgene and iodine to convert hydroperoxides to other compounds, diazomethane to convert acids and peracids to methyl esters, sulfur tetrafluoride to convert acid to acid fluorides, or nitric oxides to convert alcohols and hydroperoxides to nitrites and nitrates.
