AB - METHODS OF ASSESSING FUEL AND OIL QUALITY LABORATORY UNIT FOR ADSORPTIVE DRYING OF ORGANIC LIQUIDS V. I. Yuzefovich, I. E. Gel'ms, R. N. Yudinson, N. V. I<el'tsev, and N. Ya. Samoilova Dry organic solvents and products are used widely in physical and chemical analysis and research. For ex- ample, products with controlled moisture content are used in chromatography when determining water content for making up calibration blends; dry solvents are required in studying the properties of catalysts (determination of acidity). However, in normal laboratory practice, no small-scale preparative unit is available that would make it possible to prepare organic products with low water contents, from 0.002 down to 0.0005% by weight. We have developed and successfully applied a flow-type laboratory unit for drying organic liquids, as shown schematically in Fig. 1. The main components of the unit are a feed tank 1, a feed metering pump 2, an adsorp- tion column 3, and an apparatus 7 for determining microquantities of water in the dried product. The working section of the metering pump, which provides a constant feed rate, is made up of two 5-ml med- ical syringes 11. In order to smooth out the pulsations in product feed, the
