tained, The use of a lower alcohol such as butyl or isopropyl for mixture with glycol samples gave ill-defined breaks or no breaks at all. There are possibly other alcohols isomeric with those recommended or in the same molecular weight range that can be used but no extensive study was made of this. Less polar solvents, benzene and cyclohexane, were tried and proved unsatisfactory. Table I contains obtained on making additions of known amounts of chloride to chloride-free glycol and to samples of commercial glycol. The standard deviation from the theoretical anlount of c,hloride ion Present based on these results was 0.03 p.p.m.
The method possibly can be used for the determination of inorganic chloride in other organic materials. It was tried For diethylenc glycol and triethylene glycol and appeared satisfactory. ACKNOWLEDGMENT
