| Popis: | The authors report on a study of the principles of analytical filtration in determining the content of solid contaminants in petroleum and synthetic products, using various membrane filters. Two and a half pages of charts present an extensive collection of data weight and ash content of deposits on various filters, weight changes in the filters after six hours for various products filtered, changes in appearance of filters after treatment, particle dimensions, and content of solid contaminants for various products and filters. The authors conclude that cellulosic filters contain impurities introduced in the manufacture and so must be washed with hot water, and that, owing to the adsorption of resins on the surface of these filters, a resin factor must be introduced into the calculation equation. They find that these filters are not resistant to synthetic products based on esters of fatty acidsoor to derivatives of pentaerythritol or to aromatic and oxygen-containing solvents. They also find that lavsan membrane filters are most promising for determining the content of solid contaminants in petroleum and synthetic products. |
