Precision And Accuracy

Abstract The determination of diols and glycerol in alcoholic products was investigated by gas chromatographic procedures based on gas adsorption, gas partition, or a combination of these. The best precision and accuracy were obtained by gas-partition chromatography, using SP-1000 as the liquid phase. The limits of detection were 0.04% for 1,2-propanediol, 1,3-propanediol, 2,3-butanediol, or 1,3-butanediol, and 0.5% for glycerol. The gas-partition chromatographic procedure is fast, precise, and accurate. The preparation of standards and samples can be carried out with ease.

Low Temperature Pyrolysis

Some hydrogen phthalate esters of tertiary alcohols have been subjected to liquid phase pyrolysis. Olefinic mixtures and phthalic acid are the only products of the reaction. A study of the olefin distribution for each of the compounds pyrolyzed was made. Evidence of ionic character in liquid phase pyrolysis is presented.
