“…As shown in this paper, the ozonation method (OM) can successfully overcome these drawbacks and demonstrate attractive characteristics (high sensitivity and small testing time) of on-line polymer structure analysis. From this point of view, the application of ozone, as a reactant for polymer double bonds, seems to be very promising (5)(6)(7). In fact, the existing field of the ozone application in organic analysis is widely covered.…”

Ozonation is suggested as an effective tool for polymer microstructure characterization. It consists of the selective estimation of the carbon -carbon double bonds content (less than 0.01% mass) and their distribution within polymers. The developed technique consists of measuring the ozone absorbed by the olefin double bonds according to the ozonation reaction. The measurements were carried out by the "Double Bonds Analyzer" (DBA) device. The comparison of the proposed simple and quick method with traditional ones, like GPC, shows good correlation.

A simple and rapid method is described for the determination of alkene-l-sulfonates in a-olefin sulfonates (AOS). AOS are primarily mixtures (detergent range) of sodium salts of alkene-l-sulfonates (mixture of double bond position isomers) and hydroxyalkane-1sulfonates plus small amounts of disulfonates in a 30-40% aqueous solution. The analysis consists of titrating the sample in 98% acetic acid-2% water solution with a stream of ozone to an indicator endpoint (Rouge Organol B.S.) which is detected photometrically. In tests with model compounds, a long carbon chain alkene-l-sulfonate, sodium hexadecene-1-sulfonate, and a 1-alkene-l-sulfonate, sodium l-propene-l-sulfonate, were quantitatively determined with no interference from a hydroxyalkane-1sulfonate, sodium hydroxytetradecane-l-sulfonate. In contrast, an alternative method of determining unsaturation, Brown hydrogenation, does not quickly and quantitatively determine 1-alkene-l-sulfonates.
