Über die Bestimmung von Adsorptionsisothermen

Abstract: Einleitung. -Fur die Bestimmung der Oberflache sowic der Porengrossenvcrteilung im Rcreiche Linter 200 . & Porenradius wird iiblicherweise die Rlethodik der l'ieftemperatur-Adsorptionsisothermen inerter Gase zu Hilfe genommen. Die theoretischcn Grundlagen wie auch eine eingehende Besprechung der Arbeitsmethoden wurde schon an anderer Stellel) veriiffentlicht, so dass hier nicht mehr darauf eingegangen werden soll. Die herkommlichen Apparatetypen, wie sie auch in der obigen Publikation erwzhnt wurden, sind durc… Show more

“…Asselineau (38) and Noda (819) have written summaries on the chromatography of acids, and Fateeva (303) has reviewed their paper chromatography. Liquid-solid column chromatography is still used in this field; not only for carboxylic acids with additional functional groups (406,526,587,729,1206,1244) and sulfonic acids (515) or for a preliminary, crude separation (183, 1010), but also for the fractionation of lower fatty acids (1203) and fatty esters (343, 431). Fatty acids (566) and their esters (717) can be fractionated on undecane-impregnated (566) or nonimpregnated chromatoplates with results that are in some respects superior to those achievable by gas chromatography (717).…”

“…Adsorption. The theoretical basis of adsorption chromatography has been discussed by several authors (62,125,184,311,385,434)• Much attention has been given to the properties of adsorbents (296,933) and to the determination of heats of sorption (414,483,588,809,1030,1092,1192,1240) and of isotherms (361,418,431,589,602, 90S, 910) to elucidate the mechanism of adsorption (386,387,501,1090,1091). While the majority of the investigators have focused their attention on the three most commonly used adsorbents, charcoal (93,326,370,371,390,519,1012,1267), alumina (202,429,597,599,626,1293), and silica (299,484,590,596,611,774,821,…”
