Adsorption of Polar Compounds on Amorphous Boron

Applications of Gas Chromatography in Catalysis

“…Apart from the literature discussed above, numerous papers concerning such topics as the estimation of heats of adsorption and entropy of adsorption by gas chromatography have been published (Cremer and Prior, 1951; Schay and Szekely, 1954;Toth and Graf, 1960;Carberry, 1961;Grubner, 1961b;Beebe and Emmett, 1961;Eberly, Jr., 1962;Petrova et al, 1962;Kiselev and Yashin, 1964;Eberly, 1964;Beljakova et al, 1964a,b;Piringer and Tataru, 1964; Kiselev et al, 1965a; Knozinger and Spannheimer, 1965;Spannheimer and Knozinger, 1966;Grab and Weinert, 1966; Gillespie et al, 1966;Masukawa et al, 1967;Amariglio, 19C8;Strand et al, 1968;Dimitrov et al, 1969). Excellent agreement has been found between the calorimetric method and the gas chromatographic method in the determination of heats of adsorption (Greens and Pust, 1958;Ross et al, 1962;Arita et al, 1965).…”

Physicochemical Measurements by Gas Chromatography

“…The modification averted the necessity to measure the total area of the tailing portion of the chromatogram. (63) Gillespie, Hobson, and Gager (1966) measured heats of adsorption of water, methanol, acetone, ammonia, and trimethylamine by GSC elution data using amorphous boron as the adsorbent. The high heats of adsorption pointed to the occurrence of chemisorption and surface reaction.…”

Gas chromatography

“…Carbons, modified by the addition of a liquid phase, were recommended for the separation of mixtures of hydrocarbons and carbon dioxide (47). Manganese oxide was studied as an adsorbent (328), and the adsorption of polar compounds on amorphous boron was investigated with the results indicating chemisorption and reaction (200) . Various solids derived from phthalic acid were comprehensively examined as adsorbents in a study of Heveran (250,251), and a comparison of the selectivity of alkali metal halides for organic isomers and homologs was the subject of a study by Guran and Rogers (219).…”
