%X We used two capillary columns with different characters--SE-54 (30 m x 0.25 mm) and Squalane (92 m x 0.24 mm) to analyse C5 fractions and carbonyl compounds in the mixtures of complex chemical composition. The physical properties of some components are very similar, especially for 1,3-cyclopentadiene and cis-1,3-pentadiene. 1,3-Cyclopentadiene in the feed will directly affect the activity of catalyst. In the past we only used SE-54 column to separate 1,3-cyclopentadiene and cis-1,3-pentadiene, but the results were unsatisfactory. Later we found that squalane column could separate them fairly good, but it could not yet separate dicyclopentadiene from 1,3-cyclopentadiene and carbonyl compounds in C5 fractions very well. In this work SE-54 capillary column and squalane capillary column were used together to analyse C5 fractions, and SE-54 column was used to analyse carbonyl compounds. The results are satisfactory.
