Abstract

Adsorption isotherms of benzene and its derivatives on Spheron 6, a graphitized carbon black, are obtained using a sensitive quartz beam microbalance. From the isotherms the molecular area of each adsorbate on Spheron 6 is calculated on the basis of nitrogen area of 16.2 $A^2$. the results show that the molecules of each species are adsorbed on Spheron 6 with the planes of benzene rings lying flat on the surfaces and doing hindered rotation.

진공미량저울을 써서 벤젠과 그 유도체들의 흑연화카아본블랙, Spheron6 위에서의 흡착등온 곡선을 얻었다. 이로부터 각 흡착질의 Spheron6 위에서의 분자단면적을 계산했다. 이 값들을 비교하여 흡착질이 Spheron6 표면에 흡착될 때, 벤젠고리는 흡착체 표면에 평행으로 되며 흡착질 분자는 이 평면 상에서 제한된 각도로 회전하고 있음을 밝혔다.
