The absorption capability of cellulose tris (4-methylbenzoate) used as a gas chromatographic stationary phase was characterized by chromatographic method and the Clausius-Clapeyron equation. However, n-alcohols (C-1-C-8) were successfully separated on the column packed with Gas Chrom Q coated with cellullose tris (4-methylbenzoate).展开更多
