Title: Separating method for fullerenes
Inventor: NOBUHARA KAZUTAKA
IPC: G01N30/88
Filed: 1992-10-07
Abstract: PURPOSE:To satisfactorily separate fullerences by using a silica gel powder sintered at a specified temperature or more as a filler, and chromatographing the furalenes. CONSTITUTION:As silica gel particles, spherical and crushed ones having average particle sizes of about 3-500mum which are obtained from neutralizing reaction of alkali silicate are used, and the particles obtained by baking them at about 600 deg.C or more are used as a filler. An excessively low baking temperature can not provide the filler capable of satisfactorily separating furalenes, and an excessively high temperature makes the silica gel half-melted state, resulting in an unpreferable reduction in specific surface area and pore capacity. The baking time is differed depending on the temperature, but generally set to about 1-10 hours. Otherwise, those obtained by supporting a proper metal oxide by the silica gel particles can be used, and when alumina is supported, particularly, separating performance of fullerences is more improved. The thus-baked silica gel particles are used as the filler to perform chromatography. Fullerences, particularly, a mixture of C60 and C70, can be efficiently separated.
